I just brought a Nissan 14 ft bowrider with a Nissan 70hp 2 stroke. The 2nd time out, I was running low speed out to the channel and the buzzer in the control sounded constantly. When shifted int neutral it stopped. The water coming out with the exhaust was warm and not hot. Water pumps strongly. The powerhead wasnt unusually hot. Could it be the temp sensor or thermostat? After cooling down the problem repeats as soon as I shift into forward or rev.

Welcome to Iboats,

Go to Tohatsu web page and download a Owner's Manual on line, check page 64-65 for 70 HP warning system troubleshooting...

Happy Boating
