I have a 2 stroke motor that came with my Monty when I bought it. In good conscience, I cannot get myself to use it. I have a 12 v trolling motor that worked OK for getting it in and out of the smallish bay on Minnesota's Lake Minnetonka, but it was a little slow. Getting in and out of Carson's bay generally took me about a half hour plus each way. I am tempted to take the lower unit off the motor and bolt it to the bottom of my Monty behind the keel and mount an electric motor inside the hull. I have figured out what I need for power and duration in terms of the motor and batteries, but I am reluctant to put a hole in the bottom of the boat to mount the motor and prop. Any thoughts on how that could affect the value of the boat? Scott Larson
