I would like to upgrade my 28 lb Motorguide trolling motor with a gently used much higher lb unit. I have found several reasonably priced transom mount units. The complete bow mount units I have found are considerably more expensive. If I keep the original bow mount bracket, can any transom mount unit be mounted to the bracket? More specifically, can a Minnkota transom mount unit be mounted to a motroguide bow assembly?<br /><br />Thanks
