Since this place is dead I'll post some problems.
I usually start the boat once a week to keep the Cobb webs out. It's been about 3 weeks since the last start (been busy) now it won't idle. I took the carbs apart (dual carters 9410) thinking something got in there. All the passages are clear, jets, venturies, air passages. It will start but die abruptly. Fuel pressure is right around 6, bowls are full of fuel, fuel is crystal clear. I cleaned them again thinking I missed something. Still no go. It fires until it burns the fuel I pumped in there. It's like it's not sucking fuel from the carbs. Maybe air instead?
Any suggestions? I'm thinking of picking up a gasket set for it and see what that does if anything.
You also can't rev it on it's initial start. It's a fuel thing, but what?
