    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    I'm going to diagnose if its vapor lock or not. It sounds like a good possibility now. Everything is good with respect to fuel filters, plugs, gas, and carb, except for decent ventilation. I'm going to keep the blower on and the engine cover off when I run it for an hr or so to troubleshoot it...

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    No gas leak at all from carb..The carb was rebuilt, 2 months ago. All the internals, jets, gaskets and seals were changed. I'm going to try running it with blower on and engine cover off. See if it could be vapor lock.

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    Having an issue with my boat. I could run her for 3 hrs straight literally, and with no issues at all. The problem is, when I shut down for say 10-20 minutes and restart, the engine has major issues starting/idling and accelerating. After attempting it a few times, eventually it gets going...

    5.7 Mercruiser Starter problem

    Have you checked voltage, is it draining, maybe a wiring issue. Bad grounds are usually the culprit? Did you align the engine with the Sterndrive? Sterndrives that aren't aligned can effect the coupler and flywheel. Just my 0.2 cents. If you have done everything possible. I'd get a priest to...

    Are cheap carburetors good?

    I had the same thoughts on buying a Chinese carb on Amazon But after some deciding I bought a Carb Kit. IMO Mike's Carburetor has the best Videos on how to disassemble and assemble a Merc Carburetor. I'd watch them a few times before you attempt it. It's not rocket science. My rebuild went...

    Some possible water in my outdrive and the outdrive was making that clacking noise again. Pics and Videos Enclosed.

    Here's the sound I'm getting. In neutral and in gear. After I topped off the drive gear oil, the noise stopped. Any ideas would be greatly appreciated. A lot of clanking. Drive in neutral, obviously no clanking. Less Clanking. No clanking after topping the gear oil from the top cap of the...

    I'm getting and erratic clanking coming from my sterndrive ( Merc A1-G1 140HP 1985) When I opened the top cap to the drive hot, (top photo) I thought what appeared to be water and metal, I didn't feel any metal, I guess it was just water and suds etc.. When it cooled down, (photo 2 and 3) the...

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    I'll try opening my gas cap too see if that does anything.

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    I'm gonna pump some fuel into a glass container and check it also, as advised by an auto mechanic friend of mine.. I have an electric fuel pump on my engine so it won't be to hard to do. How would one verify the tank vent is clear. Please be specific, location etc... Thanks

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    If so which fuel additive would you recommend?

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    I suppose I could check the water separator also, which I haven't yet.

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    PS - I also noticed there was a ratty smell of gummy gas when this all was happening. It literally smelled like water was in the system, or bad gummed out gas was in the fuel system.

    Does seafoam work in the fuel system. Engine was bogging and had poor acceleration after several hours in the water.

    Today after a 5 hours on the water, I started losing acceleration as it bogged down, some times almost stalling out. The engine took a few seconds to shut down when I turned the key off, it was sputtering for a second or two and then it shut off. Never did this before. When I got back, I...

    First time pulling an engine questions

    I wonder what preventive measures one can take to keep that oil pan rust free in the future, maybe perhaps a coat of marine grease, some WD 40 etc. I'm gonna look into that, I suppose nobody does any preventive maintenance on it, or do they. It's not rocket science. 😃🤣😃
