    1980 Merc 40HP for the real Guru's

    I have been puzzling with this for a while. The timing is way out and the old trigger when rotated to the idle position would cut the sparks off. Thought it was the trigger but a new one does the same. Got to thinking. This motor has a bolt in flywheel center and it looks like the bolts have...

    Controls compatibility.

    I have a 1980 40HP Merc. I also have a 2001 quicksilver control with the same 7 pin plug. The question is are the shift and throttle actions compatible. Thanks in advance.

    !980 pos 81 40HP Mercury Trigger part # identification problem.

    40HP 2Cyl 5751264. Someone earlier has worked on this motor and replaced the stator with CDI 174-5255 and the Switch box with CDI 114-4911. Both of these appear to be correct. Bad and intermittent sparks led to checking the Trigger. Resistance measurements show the trigger to be defective. The...

    1965 9.5 Evinrude.

    I have this one up and running. Some previous owner removed the engine cover rear latch mechanism and rigged with a couple of screws. I would like to fix it correctly. I don't have a manual or parts drawing for this model. If anyone can help with a drawing I would greatly appreciate it.

    1979 140 Johnson

    I am doing a little restoration and note that the engine cover seal was attached with an adhesive. Can anyone recommend an adhesive for this purpose? Merry Christmas everybody.

    Motor has good compressions at 145 each. Replaced one power pack and plugs. Good sparks. Carbs thoroughly cleaned and rebuilt with new kits. Fuel hoses replaced. Lower unit serviced. Fired up immediately and ran but started to miss at idle and just shut down. Can restart immediately no problem...

    Mercury lower unit ID.

    I have a 90HP 1995 Merc Tracker OG165400 . Need to ascertain if the lower unit is standard or Big Foot. It has the short, very wide, upper cavitation plate similar to my 60hp Big Foot. Can anyone clarify this for me?

    This is a tricky one.

    1984 150 GT Johnson. Spark was intermittent on #5 and then disappeared altogether during checks. This is usually symptomatic of a power pack failure. Replaced the pack with a new one and still the same. Switching the orange wires leads me to believe I have two faults a bad coil on #5 and...

    What do I have here.

    According to the lists I have a 1984 150 GT Johnson STLCRD SN J5975935. I have not run this motor but it appeared to shift correctly. I have the lower unit removed to do the pump and thought to check the shift rod height. The manual calls for 21 1/16 for an '84 and 22 1/16 for an '85. It is set...

    1989 Mercury 115 inline 4 rebuild.

    Wrestled with the crankshaft bearing alignments now hooking up #1 con rod. Those of you who know know that the caps are threaded and the bolt threads don't clear the caps. Threading the bolts into the rod causes the cap to lift off. What am I doing wrong? Yes the rods cages and caps were marked...

    1998 150 60* Fuel problem.

    Idles poorly and then cuts out. Carbs are clean and rebuilt. Squeezing the bulb makes no difference. Tapping the key to activate the primer makes the motor idle smoothly. The warning beeper is very faint but I can hear one beep per second. I wrote the warning beep meanings down but I have lost...

    1992 120 Johnson No sparks.

    I have finished rebuilding the power head. Everything nice and smooth. Tried to turn it over and found the 20amp fuse blown. Replaced it and the motor turns over. Seems to turn over a little slow even without the plugs in but should be enough for sparks. Battery, cables and connections all god...

    1995 Mercury 90 Demise

    I think I know why this motor comes with a super heavy cowl. It is to prevent aluminum shrapnel from injuring the boat occupants. What a mess. I am told that this 60HP on steroids model frequently blows up. It wont be rebuilt so I have a parts motor. I will have a better idea of the reason for...

    1993 115 Johnson. Can't make this one out.

    This recently rebuilt and tested motor was out for a week and the boat sank, in shallow fresh water. Flushed the motor and no sign of sand or other crud. Stripped and cleaned the carbs. Replaced starter motor and solenoid. Flushed the fuel lines using my test fuel tank which is clean. Ran for...

    1997 50 HP Evin SPL Compressions

    Having rebuilt this motor I was surprised to find that the compressions were only around 70psi. The leak down test showed no problem. The marine shop that did the machining said that the lower compression was as a result of the manufacturer boring a hole in each cylinder to help with the idling...

    1997 Evin 50HP spark control rod question

    Trying to set this motor up after rebuild. Model #E50ESLEUS. The manual calls for spark control rod length 2.5 inches for a 12amp system and 2 inches for a 4amp system. How can I determine which type I have?

    1985 GT 150 Shift problem.

    Goes in forward and reverse ok out of water but Jumps out of reverse even with the Remote shift held, in fact it kicks in the hand when in the water. Thought I had it when I saw the horizontal shift shaft bushings shot and the shift rod out of adjustment but no luck. Everything seems to be in...

    1985 GT 150. Fuel pump question.

    This motor came to me with the VRO removed. In its place a single three tap pump 438557. B.N indicates that this pump is only good up to 100HP.The 1984 model B.N drawings show two pumps but does not show how they are connected. Is it possible to use the same two pump arrangement on the 1985 and...
