I am sure that you have been asked this question many times before, but here we go again.<br /><br />I am looking to buy a new prop for my 1997 25 hp Merc tiller motor on my Lund Rebel 16 boat. The problem is that I can't stay on plane with 2 people in the boat.<br /><br />What pitch and/or diameter would give me more speed or help me stay on plane better?
