99 V MAX 225 overheating

[jrowe13]

Just wondering if anyone can give me any info on this overheating issue. I have a 99 V Max 225 and the overheat light comes ONLY at low RPM. Once on plane the light turns off and never comes on again until off plane. Wondering if it could be an impeller or waterpump issue? Thanks for any info.

Yes replace water pump impeller or may need a water pump repair kit and or a water pump housing.
