Engine overheated after running for only 20 minutes. Changed impeller (which was needed and missing a few arms) also topped off gear lube. Started boat, water pulled into engine fine (water pumps seem to be working), engine did not overheat although ran a little rough at higher rpm's. Ran engine for 15-20 minutes-alarm continued to sound. We unhooked the wires attached to the gear lube bottle (im told this is where the sensor is) with the thought that it could be a bad sensor....... alarm sounded before engine is even started. We plan to backflush system to purge possible impeller pieces, however this would not explain why the alarm doesn't turn off because the boat is not currently overheating. Any suggestions?
