Just started using our pontoon this week, we were out today heading back with about idle speed when all of a sudden the warning signal started beeping. I looked to make sure I had a good stream of water flowing out of the pee hole and it was ok. Put the thing in neutral and shut it off for a second, started back up and it was still alarming, pushed the bypass on throttle and speed it up but it would not gain any rmp's for a few seconds then all of a sudden took off and ran fine. Made it back ok, just don't know why alarm went off, could I have been going to slow and loaded up the fuel or what? First time owning a pontoon and sure would like to know what went wrong. Thanks for any help you can give me.
