By following the same procedure each time you troubleshoot, all items in the ignition system will be tested. Tighten nut securely. Safety glasses must be worn to prevent injury. You have checked and cleaned the tell tale hole and there still is not water showing, then in all probability the impeller is aged, worn or damaged. Coat the threads of the flywheel nut with Gasket Sealing Compound. Because of this, it is essential to maintain their original positions at reassembly.
Clean the crankshaft and flywheel tapers with Cleaning Solvent and let dry.
They don't want you to be able to start the motor "in gear". Already have an account?
The new seal will not fit because part of the old one is still in the head. The prop shaft supports the sliding splined shifter dog, which when centered between the moving gears, it is is neutral, then when this shifter dog is moved either forward or rearward engaging the rotating gears, this power is transmitted to the propshaft.
These will be 1 each of a yellow wire, 1 yellow with gray stripe and 1 yellow with blue stripe.

CODE I. The only difference between the 9. I've seen pics Wiggo thanks. This button is hard to get to if you are in a hurry, emergency type situation and if the shifting lever is not precisely in neutral the starter button will not engage.
Make certain that the rings are correctly positioned in their 22 with respect to the dowel pins. I don't see a change in pitch gaining you anything without some rigging johnson 15 hp 2 stroke weight lose. Now you can wind the rope back onto the spool then locate the spool's inner peg into the eye of the spring. Go down to 6 in this article. It's like a muffler for the carburetor. Some dealers used the kits on stock motors, and others didn't they just put them on the shelves waiting for a returned complaint motor. Leaf valve may break when returned to service, causing serious powerhead damage.
Apply Black Neoprene Dip to connection.

The multimeter should indicate little or no resistance.
It surely will not be engaged accidentally. The plastic lower cowlings easy removal makes for easy access to the lower part of the block if need be. If the starter spins, the neutral safety switch is bad, OR the wire going TO the neutral safety switch has an open broken OR the neutral safety switch ground connection is bad. CODE I. His solution was to take a electricians 4 or 6 copper grounding split bolt clamp and simply clamp it around the throttle cable in an out of the way place. I've asked the guy to put it on some bathroom scales for me to get the weight but he says he doesn't have any. Anyone got one of these they can pop on some scales for me to see what it weighs??
This increased RPM is usually from to higher for the 15hp. This does not mean 12 volts, because at about The consequences are that the two bolts that attach the pivot tube to the exhaust housing sheared off. Register now. And by using direct injection techniques, Mercury Marine is also making 2-stroke outboards that are as clean running, smooth and quiet as 4-stroke outboards.
Use a heavy wire, 10 gauge or so to light a gauge of wire to "jump" the 2 large terminals of the solenoid will put voltage to the starter, but the wire will not be large enough to transmit enough amperage and will get hot fast because the starter was drawing a lot of current. If air passes through into the needle valve, it won't start worth a damn, and likely not idle well. What's new New posts Latest activity. The reason is that this tiller handle is not made of aluminum as most would think, but is a high strength nylon which may well need the backing inside support of this aluminum angle plate. For these, you may see a slight duplication, but with a more complete write-up on the article more specific to that repair.
This is the same as described under the "Trouble Shooting".
Since the solenoid can't close, it can't send voltage to the starter thru the large gauge wires.
Replace the start switch if test results are not correct.
Reinstall plug after procedure.
The timing light should indicate that cylinder's number only, and the number should only appear near the timing pointer or starter pivot screw. OMC apparently learned something on the 9. Drain and clean all fuel hoses, filters, and fuel tanks. Remove the rod caps and bearing retainers. This alignment does not have to be exact, close may be OK. Insert needle-nose pliers into slots in the ignition plate bearing and compress bearing while guiding the ignition plate into position.
That's why it's safer to test the "control circuit" small posts side of the solenoid. The 15hp you've put in the pics is a newer model than I am looking at - how do I post weight lose pic of it here?? With the motor running your bulb is no more than a fat piece of fuel hose so you can expect it to be soft at that point. Already have an account? Postal Code. Then in this case, disregard the last one, as it pertains only to a model revision that only on specific cases may be reverent to a marine repairman if problems arise.

The Outboard Expert: Inside the Rise of Johnson Outboards
However of that fails, then you will have strooke use the 3 armed gear puller and the 3 holes in the top of the flywheel like it was designed to do. The cleaning agent could drain into the starter, washing dirt from the drive into the bearings and commutator. Remove the red wire and two screws retaining the rectifier and black cables.
The weight of the float will close the float valve needle. The manual starter will become floppy and may have problems engaging the flywheel ring gear. I have been offered a 15hp Yamaha of a similar vintage. However the common recommendation is to go up one hotter range plug BR6HS for the weaker magneto ignition systems of the motors.
This completes the circuit and the solenoid closes. I could make something like that up quite easily. A motor could have one or more of these problems, but highly unlikely. As before, the last 3 letters are what you are looking for. Bythe Evinrude Outboard Company had sold thousands.
2 Stroke Versus 4 Stroke: The Choice Is Yours
The overboard water indicator tube comes off the top of the sideplate with this rubber tube just sticks out of the RH lower cowling. Now the sad part, you are going to have a hard time finding one, as there have been about 30 years of other boaters looking for the same SCARCE carb ahead of you. You may also have to grind the handle slimmer, or make a slight recess close to the head to allow clearance. It really comes down to how the cylinders are lubricated. Best in class power to weight but hard to find, and pricey, for that reason.
Search Advanced search…. Weights are here 8hp 27kg, 15 hp 36kg. The situation here is that THIS motor was designed as a 15 hp and detuned for the 9. Register now.
The steering handle is moved more to the center of the motor instead of on the far LH side. The fuel pump is the same basic one as used johnsoh the late and later motors up to at least 40 hp. Thanks all. The throttle cam plate that rotates under the flywheel when you twist the twist grip and the plate has an raised line type mark on the front of it. For the electric start motors, the rectifier uses bullet type connectors instead of screw eyes attached to a terminal strip as for the pre 93 versions. The tender is rated to 10hp but as I will put a lower pitch prop on it to use as an auxiliary on the main boat, I figure it would be relatively safe on the tender as long as I don't go daft.
On the plastic sgroke and bottom you will find numbers near the screws. Most of the time, starter problems can be traced to bad connections. For some reason even with foam insulation on the insides of the cowlings these stroke weight lose are noisier than the earlier models. The manual starter has been redesigned, moved which is then supported by 2 over arms above and in front of the flywheel with another over arm attached to the block in the rear. This can therefore lead to latch breakage. In the photos below, shown are the later and newer cowling latch system. For these, you may see a slight duplication, but with a more complete write-up on the article more specific to that repair.
2 Stroke Versus 4 Stroke: The Choice Is Yours
This could because these parts seem to be as universal as possible, fitting many different carburetors. First Name. However if you have a lighter boat and it just needs a nudge to get it onto a plane, then possibly going to the 15hp would help. The horizontal coil spring is what actually snaps under a section of the lower plastic latch. Forums New posts Search forums.
I f you are running it in a barrel and get erratic water flow out this tell tale hole, you might consider pulling the motor out, then checking for debris plugging the water intake screens. Remove the two bolts. Then when you go to start it, you twist this knob counterclockwise all the way up about 90 degrees till it bumps. Replace all damaged and worn components.
Guy has just come back to me. Here is the solenoid for most all OMC johsnon from on for the 9. But making it necessary to remove the upper cowling to make the idle adjustment. I had it permanently on the tender so didn't lift it off, but it wasn't tiny and so I'd agree Wiggo's comment that it isn't likely to be an easy lift, at sea.
Tighten the nut enough to just squeeze the cable inside the plastic sheath. Fuel Pumps : These fuel pumps are normally a pretty trouble free mechanical device mounted on the LH side of the block below the flywheel. This is directly under the carburetor area and goes down into the pivot housing area.
Always work in a well ventilated area.
Start In Gear Override for Manual Starter : One thing that many fishermen prefer, is that the motor can be restarted in gear. They don't want you to be able to start the motor "in gear".
Check that the powerhead reaches idle temperature.

These post 93 9. This allows work on the powerhead that was not possible on the pre 93 motors. This circuit controls the solenoid when you turn the key to the Start position or push the starter button. Carburetor : The carburetor shown below looks externally very much like the pre 93's but internally the pickup tube and main-jet are simplified. A light gauge wire could not carry enough current and it will heat up if held there for time enough to start the motor, and burn you if not careful.
I'd love one of the Tohatsu 9. Forgot your password? I had to cut a plastic reinforcement web out at the rear of the cowling where the rubber bumpers go. These bumpers are for support when storing the motor laying it on it's back.
Left side lower cowling repair for a Full details can be found herestrok read before you proceed. I will weigh the 8hp tonight, but I reckon that's do-able as the new 4strokes are coming in around that for an 8hp! Joined 9 Oct Messages 2, Location Oxfordshire. Phone Phone.
Weihgt titles only. These anodes are both the same part but one is just flopped degrees to be used on the other side instead of the afterthought ones of the previous years. Bythe Evinrude Outboard Company had sold thousands. And by using direct injection techniques, Mercury Marine is also making 2-stroke outboards that are as clean running, smooth and quiet as 4-stroke outboards. The other side of the Neutral Safety Switch goes to a ground connection if the motor is in Neutral. Phone Number.
Another thing is it that it is about impossible to adjust a motor trolling speed using muffs since there is no resistance on the propeller as you would have under normal on the water conditions. Usually keeping the weight near the stern will help to get the bottom free of the water. Align the drive end cap mark with the mark on the frame and magnet assembly. Sometimes especially after many years of throttle gear teeth meshing and with a lot of wearit may be nearly impossible to get this slow speed control to effectively function. The top or input gear is called the pinion gear, it engages both the forward and reverse transmission gears simultaneously, one turning RH while the other LH. Today and into the future, 2-stroke, 4-stroke, electric or diesel, the choice is all yours. Pull the rope out a few feet and tie a slip knot in it so that it can't rewind back.
This circuit controls the solenoid when you turn the key to the Start position or push the starter button. The steering handle is moved more to the center of the motor instead of on the far LH side. Then inOMC introduced the 4 stroke models which were only marketed under the Evinrude name. Hi All, Currently we use an 8hp Yamaha as an auxilliary mid 90's motor for the boat and tender.
Watch how it comes apart and you should have not problem. In the center is the manual starter pull handle. Check the leaf valves for tight closing, commonly called reed valves or replace them. Hard Starting When Cold kose The one most common problem with hard cold starting, if the motor is in reasonably good running condition, can probably be contributed to someone who uses the motor strictly for lake trolling and is prone to adjust the idle jet lower than it is actually designed for. Re: how can i make my 2 stroke 15 hp johnson go faster Get a bigger motor and put 15 hp stickers on it. Even if you tried to over tighten the flywheel nut, the flywheel could not be sucked down tight enough on the crankshaft taper to prevent future repeated key shearing.
Sure this may not be the cure all, but it can give you an indication as to where the problem loes. I would think a factory manual would have reed service procedure. You will need to also remove the idle shaft screw, turn it in until it lightly stops, count and remember these revolutions. Before installing the spark plug lead cover on the spark plug, apply a light coating of Electrical Grease to the ribbed portion of the spark plug ceramic and to the opening of the spark plug cover. Be careful not to lose any of the 22 needle bearings or the two wrist pin washers.
Carburetor Timing : If you are having problems getting the motor to run as you think it stroke weight, possibly where the timing plate is considerably advanced, you may consider doing a "Link and Sync" of the carburetor throttle arm roller to the timing plate cam. This completes the circuit and the solenoid closes. Especially the High Amperage circuit. The 15hp you've put in the pics is a newer model than I am looking at - how do I post a pic of it here??
CODE I. Johnson 15 hp 2 stroke weight lose these outboard motor repair articles, I DO NOT try to give the reader a documented list of parts needed for a jphnson, as this could be different because of running changes made even within the same modelsbut do try to document what differences I have encountered and tricks I have learned, many of which are not listed in service manuals. What's new New posts Latest activity. And the 15hp carbs are priced at a premium because of the exact reason you may be wanting to change over.
Pressure and vacuum check gearcases with apparent leaks. Manual start outboards are equipped with starter lockout mechanisms. Air Silencer The air silencer on Johnson outboards minimizes audible noise related to air flow into the johnson 15 hp 2 stroke weight lose. Tampering with the fuel system to change horsepower or modify emission levels beyond factory settings or specifications will void the product warranty. That is on the front panel, the choke pull knob is on the left side looking back to the motor. Throttle Block : These motors are designed so that you can not manually start the motor pull the rope if the throttle is advanced much beyond the start position. The thickness of the valves is not the same.
Using this code system, if the motor was sold as an Evinrude, then the first letter would have been an E johnson 15 hp 2 stroke weight lose of the J. Postal Code. I'd love one of the Tohatsu 9. What this does is not allowing the motor to "run away with itself" by electronically not allowing the motor to over rev. I have heard from more than one person that their plug had numbers that do not match any of the codes, so this kind of backs up the idea of a change after the date, as the factory changed things as time went on.

However stroke the motor is used in saltwater, be sure to flush it after usage as if there is salt buildup inside the motor, it WILL be at the thermostat area and if enough is there it will restrict the motor losr cooling as the thermostat will become stuck shut blocking any flow of water as evidenced by the photos a bit farther down in this article. Put the knob in a metal lathe, then carefully move the shank back into the knob area, deducting the. It is even better if you can rig it so that you test both ignition wires at the same time. Re: how can i make my 2 stroke 15 hp johnson go faster Why are you changing the reeds? You can NOT just throw a bunch of modifications at an engine and magically it will become a barnstormer--just doesn't work that way.
When you remove the plastic top you may notice on the bottom of the plastic at the location of this side idle adjustment screw, where the brass threaded sleeve the screw threads into may have swelled the bottom of this top cover downward slightly. The manual starter engagement dogs are on the inside of a ring in the flywheel. The fuel pump is the same basic one as used on the late and later motors up to at least 40 hp. This article covers many aspects of these series of OMC motors, but over the years it has grown to the point that I have had to split it into separate specific sections. Some of these motors do not use a choke, but a fuel primer, if this is the case, this second boss can be tapped and act as a fuel supply for the primer instead of teeing off of the carburetor's fuel inlet line. Especially the High Amperage circuit.
Typical Fuel Supply Configuration 1. With the motor assembled in a running situation this Ell is about impossible to get at. STEP 3 Test spark plug leads for continuity. Apply Extreme Pressure Grease to all sides of retainer and install between mounts.
You can NOT just throw a bunch of modifications at an engine and magically it will become a barnstormer--just doesn't work that way. Install a complete set of new rings at reassembly.
Log in. And by using direct injection techniques, Mercury Marine is also making 2-stroke outboards that are as clean running, smooth and quiet as 4-stroke outboards.
This system was common to all the earlier OMC engines prior to these years and was carried over into this series of motors thru This hole can be drilled and tapped at the upper location while this sideplate is still on the motor.
Some of those wontabee outboard parts sellers have no clue what fits what.
Bythe company had sold over 25, units. The 4 stroke driveshaft used different splines into the crankshaft of the powerhead.
Tighten the screws in stages to a final torque of 60 to 70 in. Apply Locquic Primer to the weighg flange of the crankcase and let air dry. Another like it had the red coiled plastic looped cable with a clip to attach to the operators arm. John said the replacement head kit was basically for trolling, to reduce plug fouling, in BOTH the 9.
I have comparing both the old head bolt pattern for both the and the with newer 87 style heads. And the thermostat plate gasket is simply a neoprene O-Ring. Calibrate an ohmmeter on appropriate scale. Or more than likely that they needed to keep those parts in production so that inventory restocking would not become a nightmare by being changed every year or so.
Inthe motors were all 4 stroke and the johnson 15 hp 2 stroke weight lose were changed completely, eliminating the plastic tops. These connections to look at will be the Positive and Negative battery posts, the two large terminals of the solenoid, the starter connection, and the starter ground connection. The 4 stroke 9. Inthe Environmental Protection Agency EPA put an end to the 2-stroke's dominance by enacting stricter limits on pollutants, and then inmaking the restrictions even stricter.
The shift lever is now on the tiller handle at the front of the motor above the mounting clamp screws. I made a sturdy aluminum angle then found a spot on the base of the tiller handle to attach it. OK, how do you test if the solenoid is OK or not! The cowling now separates on basically a horizontal line as compared to the older angled to the rear line. Enjoy the journey as you explore different types of boats, activities, and much more.
These bumpers are for weignt when storing the motor laying it on it's back. The other side of the Neutral Safety Switch goes to a ground connection if the motor is in Neutral. Search Advanced search…. If the motor is NOT in neutral, the neutral safety switch breaks the control circuit not allowing the solenoid HIGH amperage circuit to make contact.
Mercury SeaPro Outboards: The Outboard Expert
This indicator water, when the motor is running should be not that much warmer than the water the boat is setting in, johnson 15 hp 2 stroke weight lose it is just an indicator that the water pump is functioning and is exhausted from the engine before it has a chance to warm up. Re: how can i make my 2 stroke 15 hp johnson go faster Cupped prop may help and as has been said in many threads your set up is critical. It is my experience however that the 15 hp does not idle down as slow or as smooth as the 9. Now the best information of all that put many of the pieces together came from John Gill who was an mechanic working at Big Bear Lake Lodge in the high country of California in the early s when the 9.
The housing as a cast in receptacle for johnson 15 hp 2 stroke weight lose zinc anodes on the sides. These were designed to be used as an auxiliary power for sailboats, hence the extra long shaft. My articles are probably the most complete information you will find for the 9. Some will tell you that you need different reed valves and reed valve stops, not so on this model. The solenoid has 2 circuits, one circuit puts voltage from your battery to the starter motor.
There is enough room on these models to place it on the cable beside the carburetor. It however is about impossible to replace unless the weigt is removed as the channel where the wires are routed are hard to get to and be able to fish the end connectors out even with strkke carburetor removed. The 4 stroke motors that came out in were a Suzuki powerhead while using a lower unit that looks quite similar, but has a different number of attaching bolts, so it will not fit the OMCs. Shown in the RH photo below, you can see the location where the ground wire is bolted to the front of the block. The best known and most successful early outboard motor was developed by a Norwegian immigrant inventor, Ole Evinrude, in As for idling, I used my 94 for one salmon season trolling and it did not idle at a troll as smooth as my 92 version.
Inthe Environmental Protection Agency EPA wight an end to the 2-stroke's dominance by enacting stricter limits on pollutants, and then inmaking the restrictions even stricter. Getting Started is Easy! There may also be another boss on the opposite side. Even by using the new plastic repair epoxy, repairs are not very strong, at least the ones I have attempted. I have found a simple method to override this function, and yet not delete it, as shown in the photo below.
This usually results in significant gains on older cross flow engines and if done properly will not affect engine sttoke. Place the stroke weight lose flats against the bearing and press the crankshaft from the bearing. The only thing I could come up with was that maybe it was on the verge of failing when he took the motor out of service, just setting in a heated room allowed the internal components to break down and short out. The spark plugs may be a hotter heat range.
Lower Motor Cowling : The lower motor cowling is made in 2 pieces of a plastic type material that allow you to get to the lower sides of the motor by johnson 15 hp 2 stroke weight lose removing 5 or 6 screws. Red-Neck Zip-Tie overide. The 4 stroke 9. Inthe Environmental Protection Agency EPA put an end to the 2-stroke's dominance by enacting stricter limits on pollutants, and then inmaking the restrictions even stricter. To clean these connections, remove the Positive battery connection first, and then leave it disconnected while you clean the other connections. Joined 10 Sep Messages 6, Location In front of the bloody computer again.
Oose why it's safer to test the "control circuit" small posts side of the solenoid. This inside one required making a cardboard pattern, much cutting and bending, more bending, installing, removal and more bending. This is easier to remove and replace than the original steel roll pin. Notice the side located idle jet adjustment screw. Email Address.
Apply isopropyl alcohol to connectors, align arrows, and push together. It has been observed that before the motor gets warm and the thermostat opens, the overboard water indicator hole spews more of a volume of water than after the thermostat opens. Engine is overloaded at full throttle 7. Squeeze primer bulb unit pressure is felt. Replace any coil or spark plug lead which shows leakage.
This Carburetor is off a 9. The manual starter unit also being totally different than the pre 93s. The manual choke would be the significantly recognizable difference between the pre 93 motors as shown on the carburetor shown below. Installation is by a round head machine screw that is threaded into the LH edge of the nylon plunger lock.
Secure the cable to terminal. Also do not knock these pre electronic ignition models. Carburetor, Air Breather : No, these boxes mounted on the carburetor's intake are called a silencer.
For these outboard motor repair articles, I DO NOT try to give the reader a documented list of parts needed for a conversion, as this could be different because of running changes made even within the same modelsbut do try to document what differences I have encountered and tricks I have learned, many of which are not listed in service manuals. Also if your boat is to large, heavy or you and your fishing buddy plus gear are overloading the boat, your conversion benefits will not show. The manual starter has been redesigned, moved which is then supported by 2 over arms above and in front of the flywheel with another over arm attached to the block in the rear. Most of the time, starter problems can be traced to bad connections.
However taking a page out of the newer motors design, it may be best to consider placing the outlet Ell nearer the johnson 15 hp 2 stroke weight lose of the water jacket cover. Align the brush end cap mark with the mark on the frame and magnet assembly. Even after the new overboard water indicator tell tale was implemented, the old vent mist holes were left in the upper housing. Flywheel Indexing This test is used to identify erratic ignition operation.
Turn carburetor johnson 15 hp 2 stroke weight lose upside down and hold so gasket surface is horizontal. A tie strap can be used to check lubricant level. As a model 10R78Mwould indicate a 10 hpR ope starteryear of manufacture and M m odel revision. If the recommended number is Champion L78V which will be the new number of M, this is the non-electrode "air gap" or "surface gap" plug that fires in degrees to the sides of the plug. Check the voltage between the start switch connection and rectifier terminal.
I solved this problem by milling. Don't forget the Negative connection to the motor block too. Shown in the RH photo below, you can see the location where the ground wire is bolted to the front of the block. High Amperage direct circuit test: You have to be careful of gasoline fumes when you "Jump the solenoid".
Rumor is that the 2 cycle motors were not johnsoh after due to the fact that they knew these motors could not meet upcoming Federal EPA requirements. This we will call the HIGH amperage circuit, because it powers the starter itself. Starters can draw large amounts of current. The other side of the Neutral Safety Switch goes to a ground connection if the motor is in Neutral. This can therefore lead to latch breakage.
Then when the motor cools down, things are going to be slightly different. Oil threads of rod cap screws jhonson install each rod cap on the proper connecting rod. This voltage is supplied to the power pack to control small electronic switches SCRs which, in turn, direct power pack output to the correct ignition coil primary. The startin-gear prevention feature is required by the United States Coast Guard to help prevent personal injuries. Attach cable casing guide to throttle lever using clevis pin and cotter pin supplied with remote control adapter kit. It may be best to initially do this with the motor cover off, so that you get an idea of which way to turn this screw.
Connect the fuel hose to outboard ojhnson squeeze the primer bulb until definite resistance is felt. The responsibilities listed above are general and in no way a complete listing of the rules and regulations pertaining to the EPA requirements on exhaust emissions for marine products. This is to fine tune adjust the idle for trolling, as these motors do not have the LH side trolling adjustment knob. If the battery mounting system does not cover the connections, install protective covers. When running right and with the boat in the water, which places back pressure on the exhaust there should be considerable water mixed with some exhaust blowing out this hole.
Notice the side located idle jet adjustment screw. This was probably to improve the idle characteristics. You can successfully seal this crack with JB Weld. The overboard water indicator tube comes off the top of the sideplate with this rubber tube just sticks out of the RH lower cowling.
Inspect propeller shaft seals. Align support plate with four screw holes in powerhead. BUT this feature was not really intended to be used this way as mentioned earlier under "Remote Controls". You may have to dump the water and start over with a cleaner tank. Propeller must turn freely and should not spin off center. Re: how can i make my 2 stroke 15 hp johnson go faster i was trying to replace the reeds on my 15hp johnson and some of the bolts that i needed to take off are aginst the shroud do i need to pull the power head to change the reeds? I just thought I'd shed a little, I was there and done that!
Why do you say it's really a 15 then, what's it rated at??? Notice the side located idle jet adjustment screw. I often get inquiries, which I try to answer, however most of the time, the information requested is there, if that person would have taken the time to read farther. This push button system could be considered hard to get to by some as it is quite out of the way. The thermostat housing was left on top of the head, but was changed somewhat and made of plastic that uses a round formed O-ring type seal.
If the battery mounting system does not cover the connections, install covers. Keep me signed in. Observe proper wire routing and ignition timing.
Here we will coach you thru the testing so you can evaluate your own situation. Notice the side located idle jet adjustment screw. The oil is consumed and the oil tank h; must be maintained, replacing oil as it is used up. I document here what I have encountered, so that I can go back and read my own writings if something pops up years later. When fitted the aluminum is slightly smaller that the plunger lock body and is offset to the left so that in use it is pivoted upwards in a vertical position with the top edge being just high enough to prohibit the lock from being pulled inward buy it's spring system. Joined 7 Sep Messages 8, Location Sussex. Bythe company had sold over 25, units.
Use a wire brush or battery terminal tool to remove corrosion buildup. I know Garry has a picture. The water coming out of it will not be hot because it has not had time to circulate thru the block's water jackets. If necessary to remove the spark plugs, be sure to keep the spark tester away from open spark plug holes.
