1995 Speedster - Starboard Engine Issues

[dwhee87]

The starboard engine starts fine, and idles around 1500, but when I try to accelerate, it either dies, or unless I really baby it, lags around 3000 rpm for about 5-10 seconds, then shoots up to full power (or wherever I have the throttle set). Once it gets there it is fine, and responds to the throttle properly.

This started a few weeks ago, when I was beached for several hours (waves lapping at back of boat). When I left the beach and headed for the dock, it started acting up. When I got to the ramp (5 minutes away) and got it up on the trailer and pulled the plugs, it drained for 15 minutes. I realized that the hull seal behind the rub rail was leaking. When I got it home, I took the covers and filters off down to the carbs and dried everything out & changed the plugs. None if this seems to have fixed the issue.

I cleaned the fuel filters and the carbs yesterday before heading to the lake. I used carb cleaner (sparingly). Still no change. Any ideas?

How did you "clean the carbs"?? if you sprayed it down the venturi, that doesn't do anything. You need to disassemble them, give them a proper cleaning, and verify that each port is open.

Also... don't continue to run the boat like this. If you aren't properly getting fuel to the engine... you aren't transporting oil to it's internal parts. in what your are describing... it can go from needing an hour carb cleaning, to a full engine rebuild in a very short time.

Thanks for the quick reply, Doc. Sounds like I'm going out with friends today.

Does the 95 Speedster have a water separator filter? I can't find one on any schematic.
