[QUOTE="muskiemike12, post: 290178, member: 4897"] Well that changes everything! There is no way a 17" pitch is going to turn near max rpm's on that boat. Running that prop in the slip calculator leads me to believe your tach is reading correctly. That prop would be better suited on a 60 - 70 hp motor. A 13" pitch should put you around 5300 rpm's. BTW the operating range on that motor is 4500 - 5500 rpm's [/QUOTE]
