    Re: port 305 stalls on shift. YouTube video attached.

    Re: port 305 stalls on shift. YouTube video attached. It starts instantly. Revs up no problem. But as soon as you touch F or R it stalls instantly. No hesitation.. no effort. I'm suspecting a bad neutral safety switch. Or does the shift interrupt need to be tuned? I know the previous owner...

    Forward or reverse blows the ignition fuse. Need advice.

    I've been searching for a solution here and I've seen similar topics but nothing yet that matches. 1990 Avanti 2955 with twin 305 engines. The engine starts and runs, revs up, and idles with no problem. But as soon as I move the throttle in to forward or reverse the port ignition fuse pops and...

    Finding moorage

    This is becoming incredibly frustrating. I must have made over 50 phone calls by now around the Seattle area. There are plenty of marinas here but it is damn near impossibly to find moorage for anything over 28 feet LOA. - And I had done my homework in advance to buying anything. My bayliner is...

    Engine noise at idle. YouTube video attached.

    2955 Avanti with twin 305 v8. Something doesn't sound right. Any ideas? https://youtu.be/WABTv8EN7kw In particular I'm talking about the Sha Sha Sha noise. Sounds like a vacuum leak to me.

    Troubleshooting exhaust cooling.

    Planning fuel for a longer trip

    I bought a boat on Saturday (1990 Avanti 2955) and I'm having a mechanic give it a check tomorrow. If we're in good shape I need to eventually move it to new moorage. It will be between 80 and 100 miles by water on the puget sound. It will just be a slow cruise and I expect it to take all day...

    Help identify this exhaust part.

    I've attached a photo of what I'm looking for. It's the bit that joins the riser to the exhaust system. It looks like it should be a 90* plastic elbow that joins with the oval fitting. The boat is a 1990 2955 Avanti with twin 305 engines. Engine serial number is: 0C761486 This part would go on...

    Engine cranks but won't start.

    I'm having some trouble with a 305 Mercruiser on a 1990 Avanti 2955. My observations: a. The engine cranks at a good rate but there is no sign of ignition. b. I removed the top of the carburetor to check for gasoline and it seemed wet and I saw fumes rising when applying full...
