So I just put a new gasket on the tuned pipe/manifold joint. Thought everything was great. I followed youre directions Tiggerman...Thanks much for the help. I just got back from the boat ramp where I backed the boat down and started it still on the trailer (weather was bad). Well, good thing I left it on the trailer. The port engine with the new gasket was started first. She started up and I noticed smoke and water coming in the bildge pump. I guess this is because the boat was tilted from being on the ramp still??? The engine ran a little rough and hesitated to idle. But, the right engine started and won't rev past 3 grand, even at full throttle. It also won't idle at all. Sounds like a carb propblem to me, she's just not breathing. Just wanted to know what anyone else thought.
Would it be possible for exhaust to leak in from that blown gasket and get carbon build-up in the carbs? I did run it with the bad gasket for about an hour to get home. That's the only thing I can figure. Strange how the bildge pump lets in exhaust and water. Isn't it supposed to keep water out?
If the Carbs are dirty, will the fuel additive and spray be enough (please say yes)

Thanks much,
steve

I can't or don't understand what you are talking about when you say this was coming in the bilge pump..... Do you mean exhaust and water in the bilge area? If so, check all the hoses that hold the exhaust parts together and make sure one hasn't come off or has a hole burned in it. As far as the engine not revving past 3000 RPM, it won't (or shouldn't) while the stick is in neutral. Mine idles pretty rough out of the water as well.

I know it sounds strange but yes smoke was actually coming in the bilge pump. It was making "smoke bubbles" in the water that leaked in the bilge pump. I think the "one-way" valve is shot...maybe. As far as not revving past 3000 rpm's, that was in forward, nuetral and reverse. Only one engine won't rev past 3000. It doesn't sound like it is being limited to 3000, it sounds like it is bogged down like too much fuel/oil. It does this in and out of the water. Just wonding if you ever heard of anything like this.

Check/replace the plugs and see what happens. Let me get this straight.... The engine that had the bad gasket is the one not running properly now?

No, it's the other engine, the one that didn't have the bad gasket. I'll get new plugs and see what happens. It may take a while because I am moving on Wednesday...lots o' fun. I just put some carb cleaner in and started it and a lot of black stuff came out the "bad" engine. The other one was fine, just didn't want to idle. Is it possible that I got some water in the carbs since there was a substantial amount of water in the hull (over the carbon/ss rings). Neither engine wants to idle even out of the water. They used to idle fine out of the water. I just don't know what the problem is.
