Trolling motor wiring

[Zaxxon II]

I have a 35 lb thrust Minnkota that jerked my old boat around when on speed 5. The new boat is the same size (15 1/2 ft)fiberglass and it barely moves. All five speeds work well and the motor seems fine. The battery is brandnew and fully charged. The wires are 8 or 10 gage. the boat weighs 1600 lbs. There is an inline fuse just before the battery that is lighter wire. Is this fuse necessary? or what else could be my problem.

Hi Zaxxon. That 8 or 10 gauge wire is too light. You need 6 gauge at a minimum. Also if the fuse wireing is lighter, that needs to be changed too as that is your weakest link. I would leave the fuse in the system though. It will protect your motor from an excess amp draw. Hope this helps.
