I have a 87 Suzuki motor, it has been overheating and I am trying to figure out the problem. It is pumping out water and idles fine. The warning beep goes off when run fast. The impeller and thermastat were replaced about two months ago. Any help would be appreciated.

Is it ok to run the boat at low speed with these characteristics?

Welcome to iboats :) ....... how hot is the water that comes out? Can you figure our where the motor get's hot? It could have a blockage somewhere ..... do you run in salt / fresh water?

The water is warm coming out and I am not completely sure where it is getting hot. I run the boat in fresh water.

What I mean is, is it definitely overheating?, cause it could be a faulty water flow switch ....
