I have a 95 Travis XL 18 1/2 ft Rajun Cajun bass boat. I am lookin to replace the trolling motor and was wondering what a proper sized TM would be. The old Johnson TM, I think is, 45lb 24 volt. I fish fresh water and some river systems. I upgraded to a 898 Huminbird so I guess a Minkota would be the best choice. The Minkota will link with the Huminbird.
