Have no idea other than making sure you have the right transom height.
I have a 35 HD Sport, stock, on a 17x50 GatorTrax, running 24-25mph with three guys, 120 quart ice chest full of fish, trolling motor and two batteries.
My motor is a non cdi with 47 hours on it, it keeps getting stronger the more hours I put on it, kinda weird.
