i have a 1992 BassTracker TX 17 with 60hp Merc. i currently have a 30lb thrust minn kota and a Helix 5 DI fish finder. i am going to upgrade either the trolling motor or the fish finder. my options are add a Garmin 7 SV or upgrade trolling motor to a 45 lb thrust remote trolling motor. i mainly fish Watts Bar, a muddy lake part of the TN river system.
thanks for any advice
