Im looking for some advice on changing my MK trolling motor from a 42″ to a 52″ shaft on my 06 Puma? If I use the existing bolt holes the back end of the trolling motor base rides up on the hump for the panel where the ACC, Motor Trim & Light switch plate is mounted. Do I want to try to shim under the base to make it level or do I need to move all 2 1/2″ foward and drill new holes? Im wondering if I drill the new holes foward, if its not going to be to close to the front edge and put the motor to far out in front of the boat. Anyone with knowledge of doing this switch? Thanks for any help ahead of time.
