I have an 07 moomba outback with 65 hours on it. I have had it winterized by dealers both years. Last year the breaker was popping on my heater so I had the dealer take a look at it, when getting winterized. They just ran the fan and the breaker never popped. So this spring I put the boat in the water 5 minutes breaker pops. The dealer is an hour away in muskoka. Is there something I can look for at home.
