I recently bought a 14' Lowe 1410v aluminum boat without a motor. If I remember right it's about 65" wide. The boat is rated for a 25 hp motor. I've been browsing around for motors and found a few 18hp and 25hp. My question is will an 18hp motor be enough to power my boat? There usually will be two people in the boat, battery, trolling motor, and basic fishing gear. I don't bring much out. The one I am really looking at is an 18hp Johnson, early 70's model. The only reason right now I am looking at the 18hp is cost, much cheaper than a 25hp. Will the 18hp be enough or should I wait and max it out with the 25hp?
