Does anybody know what size/amp circuit breaker I should install between pos battery cable going out from battery switch to my motor. Yamaha 115 4 stroke. Cable is 2AWG gauge and the run is about 12 foot from the motor to the battery switch. Thanks.

I wouldnt install a breaker, the engine is already protected, just hook the battery cables to the engine in the proper place and to the battery or switch to the proper place,, you could have a breaker on the house wires. I would put about a 30 amp on the house.
