I have searched the forums a bit but have not found much info. I have an older 9hp gdlt and I am thinking of swapping the motor to a 13hp predator from harbor freight. Can anyone tell me if this will be strait forward or if I will need additional modifications other the a new prop. Anyone have a link or a how-to of unhooking the shaft from the motor and reinstalling it?

The 9hp a 3/4" or 1" shaft, I am almost certain that the Predator is a 1" shaft
