I have a 1995 OMC outboard and the alarm keeps going off at 3/4 throttle and stops when I back off does anyone have a clue what it could be (new water pump and thermostat)

What motor do you have?? I had a very similar issue with my 1992 115 crossflow. It was the water deflectors that were restricting the water flow around the cylinders. Which caused a lot of gunk to build up in the water jackets. Is the pee stream normal temp when the alarm comes on? Check out my thread labeled
