i have 18ft teal with a yamaha 55hp yr 1983. boat struggles to plane, engine will fully rev but takes a long time to get on the plane. engine has a 13 pitch prop at the moment. any ideas to solve this problem would be appreciated.
thanks justintime, will check this weekend, will let u know if your suggestion was right. if not problem do u think a higher pitch prop may be required, to give extra torque.
I reckon your pitch is too low which is pretty obvious if your engine is easily taking full revs, you would need to go up to about 15" pitch assuming there is no hub slippage and that does not happen very often.
