    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    no kidding, Lou! Thanks Rick now I know what that thing is. As promised here are more detailed pictures of the broken crank. Could it just be a material defect or fatigue? Also I noticed now that the crank is out that there is about a 1/4 of an inch of longitudinal play in the cam shaft. With...

    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    This is all extremely interesting to hear you experts exchanging thoughts. Wow, what did ever happen to that poor engine? The number on the crank is 10105865 2. What does the 2 stand for? The break is right in the middle of the crank between 3 and 4. What do you call those polished sections of...

    .....continued from "Engine Removal on 1988 Sylvan" We had 2 nasty hurricanes in the last 3 months and I am just now caught up with cleaning up everything. 2 weeks ago I was finally able to start taking the engine apart and to my surprise, the engine looks very good inside. No visible...

    Engine Removal on 1988 Sylvan

    I am in the process of pulling the 4.3 ltr Mercruiser engine from my 1988 Sylvan bow rider. I have arrived at the point where I need to undo 2 more bolts and I am ready for the big moment to lift that baby out of the boat. Not so fast says Murphy and sure enough I cannot loosen the 2 bolts of...

    Broken speedometer lens

    Recently I cracked the lens on my Sea Doo speedometer. It got caught under a dock, unfortunately. The speedo itself is fine just the lens is cracked. Does anyone out there have an old unit of whatever, which is kaput but has the right lens, that is still undamaged. I was wondering if you let me...

    Servicing my 1994 GTX jet pump

    I was wondering if anyone knows of an equal or better substitute synthetic oil that I can buy at an auto parts store, West Marine or other source that I can use instead of the Sea Doo Jet Pump Oil P/N 293 600 011? Also what is the proper way to check the oil level in the cone? Cone facing up...

    Need carbs overhauled on 1994 Sea Doo GTX

    I have a set of dual carbs (I assume they are Mikunis) with Vortex flame arrestors on my 1994 GTX. The Doo has been sitting for 3 years due to needed repairs. Now I am trying to get it started and it will start with starter fluid, but it runs badly and stalls in low rpm. At midrange to high rpm...

    1994 Sea Doo GTX blows 5 amp fuse

    By reading related posts regarding the subject of blowing fuses I have answered many of my questions already. I am pretty sure that I fried my MPEM. Before I go out and spend the money on a replacement MPEM I want to be absolutely sure that the MPEM is the problem and not something else. I read...

    Chrysler Outboard model 907HB

    I just received an old Chrysler outboard motor model 907HB, serial number 11191. I don't know much about it. I fond out that it is a 1976 model and has 90HP (correct me if I am wrong). Does anybody know if it is a 2-stroke/cycle engine or a 4-stroke/cycle engine. If it is a 2-stroke what is the...

    1986 225E engine dies in idle

    I actually have 2 problems. When the engine is running a tiny amount of oil leaks through the center bolts on both sides of the intake manifold. I tightened up the bolts slightly and the leak stopped on one side but still trickles up on the other side. I don't see any water in the oil. What is...
