My dad has a 1988 gambler 183 he has 6" set back and is currently running 25 trophy plus..his holeshot is not to his liking and he wants more holeshot and doesn't care about top end..what prop would you guys recommend? He is turning a little over 5000 rpms on 1988 black max 150.. Did a compression check today and the motor is 120 across the board and is strong
