Trolling motor wiring


Justfishing

Question

I have a 16' aluminum fishing boat. I need to run the wiring from the trolling motor in the front to the battery in the transom. It is a 12V Motorguide with 46lbs thrust. I will be adding about 10-12' to the wiring. What gauge wire do I use.

Also try a small mom/pops hardware store. You will want to get a inline fuse put on that too to protect against any surges. Most warranties do not cover replacement without a fuse in place.

you can go to about any boat dealer and pick up a 30 amp circuit breaker. they are cooper bushman marine circuit breakers. you can go as big as a 40 amp but a 30 will work pretty well. you should also be able to go to your local dealer and ask them for a couple of 8 awg couplers and they should be able to help you. if you can't find it let us know and i will contact one of our local dealers and get you a couple sent out. good luck

You will want to use a relay instead of a fuse, and I would call motor guide to see what size they recommend. My guess is a 40 amp would do the trick. I run a 55 thrust and was told by Minkota that it may push as many as 43 amps out of it so I ran a 50 amp to be safe.

Go with a circuit breaker sized for your motor, check with a dealer if in doubt. The advantage of a circuit breaker over a fuse is that it will reset instead of needing to be replaced like a fuse. Over sizing it defeats the purpose and may cause damage to your equipment.
