I'm trying to understand prop logic in determining correct prop for my 17ft 83 Larson Mach I Runabout<br />I just installed a 95 150hp Johnson Oceanrunner with a 14 pitch prop. Boat is like a rocket out of the hole. Performance is real good,once I got used to triming adjustment. Motor was originally on a 23 ft Mako with same prop. Person I got the motor installed a newer 150 Oceanrunner on his boat but with a 17 pitch prop. Called me today and asked if I would mind swapping props as he claims performance on his is less than he had with the 14 pitch. My question is what will the 17 pitch do differently on my boat. I have a Tach on order as my original one was no good so I cant check RPM til its installed. I am hesitant to swap without getting a second opinion. Originally he told me 14 was the prop to go with on mine but now he feels 17 would be better. Who would make out with the better sinario is where I'm at..<br />Thanks for any feedback.<br /><br />--------------------
