Can anyone tell me, with a 1990 Bayliner / Mercruiser 3.0 135hp, what the engine's top operating rpm is?<br /><br />And also is there a way to know what pitch the prop is on it? I asume is is the factory prop and I know it is a 14" diameter because it is 7" from center to tip of one blade. Is there a way of measuring the pitch?"
