That is a valid point. The critical issue is whether the wiring is capable of handling 60 amps. I am sure in newer boats it is fine, but this 1999 that I am setting up may not have been wired back then to handle the load some of the new motors demand. It currently has an in line fuse and I have not pulled it yet to see what it is rated at. That is what I meant when I said the purpose of the fuse is to protect the wiring in case of a short in the device it is powering. Mine has never tripped the 50 amp, but yours has more bells and whistles than mine so hard to guess what it draws. Somewhere there is a chart that shows maximum amps for specific gauge wires but I have not looked for it yet. Actually it may be stamped on the wire. I know house hold wiring has load capacity stamped on it and the electrician matches the fuses in the fuse box to the wire specs but I am not all that familiar with DC characteristics.

What I am rambling around trying to say is if you put a 60 amp fuse in line in a wire that is only capable of handling 50 amps and you put a 60 amp load on it, instead of the fuse tripping, the wires will melt and may catch on fire.

Sweet! I know you're glad you got it. Now go get some fish!
