Hello there,

Got my boat going for half an hour going at medium speed, no problem. Then I slowed to a bit faster than trolling, 10 minutes later the whistle came on indicating over heating. I stopped engine and waited until it cools-no more whistle when I restart engine. Then it shuts off after 5 seconds. Could not get it running for more than that length again. Had to call for toll.

Any ideas why it does that?

Thank you.
