circuit breaker needed?

I have a 12 volt 54 Pound thrust motor about 4' from battery. What size wire do I need and do I need a circuit breaker or fuse? what amp circuit breaker is needed? Where do I buy one?

boat places sell little circuit breakes just for that about $2to$4.00. To size it look at facts of your troller motor, find out how many amps it pulls at wide open, should of come with motor or call a dealer. If fuse blows on water & u forgot spares you up creek. For a few pennys more u get breaker style u push button & u good to go. My breaker fits right on top batt in batt box.
