Setting up my 18 lund fisherman for trolling. Has a 2006 9.9 mercury 4 stroke kicker. No electric trolling motor,batteries or charger. So to get all the electric trolling equipment its looking like a $3600 investment!! without the helix 10! Wondering if a autopilot is the way to go? I like the helix 10 for a combo unit. Right now it has an old lowance 4 inch xc 25 or something. Any ideas ??
