Now that I replaced a 185 pound 48HP with a 320 pound ETEC 90 I up graded the powerwinch on the trailer. I had a 1500# winch which strained to pull the boat in. For Christmas I got a 2500#. The problem is that is pops the 30 fuse inline fuse. The wire is the stock "accessory" wire on a 1996 S10. I have a 40amp circuit breaker that I could replace the inline 30amp with. Would that be to much for the wiring? Is this a fire risk?

Thanks
