I was out in my boat today and it was running great. I stopped for a minute to swim and got back on the boat and tried to start and it was turning over the first few times i tried to start it and then it started making a noise and it wouldnt turn over. It makes a weird noise likes its not getting any fire to it. The impeller sounds like it is turning and everything seems to be clear. The battery is faily new and the impeller is new. Help please!
