I have a 40 horse Yamaha. When it is idling it runs good, there is good water pressure. When I drive it 1/2 mile to a mile then the Alarm keeps going off. I can throttle back and let it idle for a few minutes and the alarm will quit and then I go another 1/2 mile to a mile and it starts alarming again.
Does anyone have any idea of what this could be? I have been told it could be thermostats, sensors, and/or heads.
Thanks for any help I can get.
