I have this motor on a 17' McKee Craft, I have heard of many people with 150s on boats much bigger than mine running 21-23 pitch props spinning 5500-6000 RPMs, I have a 14x19 prop and spin around 4200 RPMs at WOT at about 34 MPH. I just tried it out with a 15x17 and got it to 37 MPH at 4800 RPMs. Motor seems to be running fine, checked all plug wires, great thick hot blue 1/2" streaks, carbs all cleaned and working fine, seals/gaskets all good. New fuel pump. I am wondering if a previous owner could have put a foot on this motor that has a higher gear ratio. How can I check my gear ratio and what is it supposed to be??? Hopefully I can check ratio without pulling the foot off. I defiantly believe that this is not the original foot it has the four bolt bearing carriage instead of the tabs and the internal water screens.
Thanks Sparkie
