hope you didn't miss your fishing trip.

Yep, by the time we got everything figured out it was too late to go, besides I'm glad I didn't get to go due to the cold snap that came in... Maybe one day next week....

I would hate to think that my service wiring is protected by a 40 amp breaker.
The trolling motor uses a 40 amp breaker, but the largest breaker on the main
wiring for all the accessories such as you mentioned should only be protected
by a 20 amp max, but more like a 15 amp breaker. If you get a short at 40 amps with the small wiring, you will see lots of smoke before the breaker trips..Good luck..

Main breakers are sized to protect main feed wiring. Thus breaker is sized according to size of wiring. Individual electronics are always required to be fused separately. Many boats have additional breaker/fuse panels that are complanion to the accessory switches and many accessory switches are fused at 5, 10, 15A. I'd believe the motor draws very large amounts of current when starter is engaged, my wiring is fairly large from the starting and accessory battery

Yes my main wire of the acc. is very big to the hot side of the battery, is as thick as the main motor hot wire. The wiring system on my boat as I can tell is very impressive. That is why such a big breaker.
