I want to buy a trolling motor for my dad, I've never used trolling motors much and don't have a sense for thrust. Motor would be a bow mount hand controlled on a 21' aluminum open boat and be used to putt-putt along weed lines under the nicest of conditions for at most an hour at a time. Imagine, " it is a nice calm evening, lets go cast for bass at dusk", not "lets pitch baits all day long at a furious pace". What is the minimum thrust that would move the boat slowly against a slight breeze to keep in the fishing zone?
