That would depend on a the answers to a number of questions.
Do you want a cheap conversion? Or state of the art hi-tech, synomonous with expensive?
Do you want batteries as a power source? Or will a small generator meet your needs?
Our present tech level, liquid carbon fuels are still more efficient at storing more energy than batteries.
How many hours do you plan to be out on the water away from recharge electrical source?
How much HP is the McCulloch rated at? Propeller diameter and pitch? Gear reduction ratio in lower unit?
How large a boat do you want to propel with this electric motor and at what speed?
I can give you some simple options if I knew these answers.
If you want to get gnarly over the possibility concepts, you need to enlist an engineer or two.
