Trolling Motor Question

[smallie.huntin]

When I bought my boat there was an inline fuse on the trolling motor battery.  I have a 37lb thrust Motorguide TM with a 12v battery.  Does anyone have any idea what size fuse I should be using in this?  My cousin has a much newer Motorguide TM and in the manual it says to use a 50 amp.  I want to try and avoid putting in a fuse with to high of a break point for obvious reasons.  

Thanks guys.

Sorry, I can't help with the amperage, but you should consider replacing the fuse with a breaker switch.  Sucks to be out on the water and blow a fuse.

Could I get a breaker at any hardware store or is this something I would have to get at basspro, cabelas, or online?

I would say probably not unless they had a marine dept.  If you have a marine store like West marine or Boaters World you can find it there.  Probably find one at a boat dealer too.

Try to contact a motorguide dealer in your area and ask them.  It is probably going to be a 40 or 50 amp.  A dealer will also sell the breakers.  I have a manual reset small gray shortstop 50 amp on mine and it was around ten dollars.

Pounds of thrust dont apply much here. The fact that they all use a 12 volt  D. C. battery is what warrants the use of a 50 amp fuse or breaker which is more intended to protect the wiring first before it protects the motor.

Really?? I always thought you could use the assumption that for every pound thrust,it draws about 1 amp?

I doubt a 30lbs TM draws as many amps as a 55lbs TM at full throttle.I might be wrong though.

Check around but I think a 40amp braker should do you fine.

I will try and call a motor guide dealer tomorrow.  Thanks for the input.
