We just picked up a 1995 330 DA with 7.4 v drives. When the boat has sat overnight (or small week) the port engine has to be spun over to prime the carburetor, maybe 10 seconds or so, then pump the throttle a few times and starts it. Once it’s running it runs well.
Until yesterday, it was great all day but we came back to the slip for an hour to avoid some weather. When we fired it back up it started fine but as we were idling out the port engine quit. I restarted it (and it quit) about 3 times before it finally wouldn’t even try to start, just turns over. The P.O. told me the choke was probably adjusted too tight and that I might need to back it off. I did that, still nothing. It’s not getting fuel and I believe the fuel pump has failed.
BUT- when I removed the flame arrestor I discovered that the engines have Holley style carburetors. I think the boat is supposed to have QuadraJet carbs. Anyone see this before or did MerCruiser ever install Holley carbs?
