Trolling Motor Circuit Protection

[bluka43]

I am using (2) 12 Volt trolling motors for my Motor Guide 12/24 volt trolling motor. Should there be circuit protection at the positive post on both batteries? And what type protection is best?

Yes, you should have a breaker on both + terminals. How many lbs thrust is it?

Try one of these, kind of depends on how you want to mount it but this is what you want.

I had just recently noticed when replacing the two trolling motor batteries that only one battery has a waterproof inline fuse with a 30 amp fuse in it. The other battery has none.(it looks like there was one on it and it was removed for whatever reason). I have had no problems as of yet with 30 amps, but the wiring from the batteries to the trolling motor is #8 AWG. The circuit breaker looks like the way to go on each battery. Perhaps I should stick with 30 amp because of the wiring?

I had a 30amp on my 65# Minn Kota it poped at full speed after 5 minutes. Minn kota recomended 60 amp, just make sure your wire can handle that much curent!

Yes, the wiring is what concerns me. Due to the fact that I have had it caught in weeds, briefly of course, the 30 amp has never popped.

My guess would be that the two fuses had to do with the 12/24 wiring, and maybe the prior owner converted it to 24V only. You need to trace out the wiring to be sure.

If you never popped the fuse when running full tilt, go with a 30 amp manual reset breaker (assuming 24V). From a rough order, thats right around what your 24V motor max draw is. Given your wire size, do not go higher than 40 amp breaker. I would place the breaker on the + terminal that feeds the trolling motor and you only need one.

Ok, went with the 30 map manual reset breaker. Went fishing yesterday.....lots of wind....trolling motor did fine on 12 and 24 volts, no problems. Thanks.
