I am wanting to put a new trolling motor on my 16' aluminum crappie boat. I had my eye on a MinnKota Max 55 pound thrust stern mount. There is not enough room on the bow for a regular bow mount foot control that is why I have to go with a stern mount. The MinnKota I mentioned has mixed reviews. Does anyone have one they have bought in the last year that they could brag or complain about? One of the concerning features is all the models with a Maximizer feature also have a variable speed control which to my understanding causes RF problems with sonar.
