I have a 1988 19.5' bayliner trophy c/c with a 1989 force 125. when running at WOT i am @ 3800 - 3900 rpm.. i am turning a 13x19 stainless. the engine seems to be running well at idle(no missfires) and when reving it without load, it will max out the tach @ 6000 rpm.. i have tried a 13.5x17 and it ran @3500 rpm.. any sugestions what i should try next? either a different prop (size sugestions please) or should i look into it being an engine problem? i have good compresion on all 4 cyl and all cylinders seem to be fireing (check by pulling wires on plugs and rpm droping w/ each one)..(is there a way to check at high rpm?) also i am running on a new tank, lines, ball and water seperator with carbs being drained..please help..i have been trying to get the boat into the right rpm range for 3 years
