Thanks, I was wondering about that and I will ask my boat guy more about it. The motor will have an aluminum coil but I also got one of those tcs manifolds for extra cooling...it's kinda trick looking and hope it helps with the temps. We also have cool summers about 70deg and very cold water up here in alaska cooling should not be a problem at all. And it doesnt sound like I'll be pulling big amps so i think I'm good...thanks.
