During normal operation engine runs fine. 20 min later RPM drops to 2200ish. No response to throttle position unless lower then 2200.
Putter, putter then pick back up but ultimately drops again and back to the ramp I go slowly.
Compression: 120 on all but bottom at 115(always has been for last 8 years)
Spark: 7/16" and strong.
Fuel: Bulb pressurized, filters new, fittings new, pump new, tank new.
Here is the thing, I had water in the tank. Boat still ran like a top but I stopped and replaced the tank before running again.
All symptoms after restart with new fuel everything up to carbs. There is an appearance of unburnt fuel from exhaust.
Plan is to rebuild carbs, sync/timing, test limp-mode senders, temp, pressure and oil level....but what else?
New plugs look same but not dry.
Salt water boat.
I just dont want to miss something while I have everything apart.
Yes, I have and use the manual.
