I just bought a 1990 wellcraft 170 classic, with a 140 I/O merc cruiser. I noticed that the had a sticker that said V8 on it. could that be right or is it just a sticker. the engine is a 4 cylinder and I dont want to ruin it. <br />I did take the boat out and it ran real well and was fast.<br />Alsowhat is the top RPM I should run the boat at.
