Thank you for the reply. I'll try to be more descriptive about the problem: The engine starts fine and RMPs will slowly rise under light throttle, however, at low / no wake speed it sometimes feels as though it's 'missing'; if more throttle is applied, after choking a bit, RPMs will rise, but never exceed 5000 (top cruising speed of 17-18 MPH). Again, when on a lift with hose attached, engine runs fine and RPMs will go to max (9000?). As for compression and spark . . . the plugs have been replaced, then after an hour of running at or below 5000 RPM, they were pulled (discovered fouled) and cleaned. Also, the fuel was completely drained, fuel lines cleaned and fresh fuel added. I think if it were a fuel issue, the problem would persist whether in the water or on a lift. I agree with your thinking that it's hard to completely ruin an engine by over-filling the oil. I'll have the shop check the impeller . . . I've heard that may cause this type of problem (I don't understand why). Lastly, I'd welcome suggestions about a reputable / qualified mechanic in the Tampa / Clearwater area. Thanks for your help.
