Hopefully, you haven't bought a motor yet. I have owned bow mount, transom mount, foot control, etc. and had them installed on boats from 12' fiberglass, 14-17 foot aluminum, and 21 foot fiberglasseverrything from 25lbs to 75lbs. Believe me, go with the biggest (most lbs of thrust ) you can afford-you won't be sorry, especially if the wind comes up (you never know when that will happen) you will very glad you have the extra lbs of thrust.
There is a calculation that someone may have provided in a response, unfortunately I can't remember it. I'm sure either motorguide or minn kota have the calculation on their web site. Another consideration is battery power some are more energy conscience than others, it all depends how long you plan on staying out before recharging. Check out the calcualtion for YOUR boat, one can't compare a 14 aluminum j boat to a 21 ft Rnager bass boat (a little bit of difference in weight, draft, etc.) Best wishes! Bigger is better (within reason $$$$).
