What would cause the Water control panel light (and buzzer) to activate on my Yanmar control panel in the cockpit? It comes on after running the engine for at least 10 minutes, but not every time.

That "Water" alarm probably means "high temperature" in the engine cooling system. I can't imagine it meaning anything else. Why only sometimes many have to do with the load you are putting on the engine at the time or other variables. I would not run the engine until you sort out the cause of the alarm. As we were taught in Nulear Power School - Believe your indications!
Thanks Smokey73! I suspected as much, just not sure how to troubleshoot. I haven't had the boat very long, and this is my first diesel inboard. I'm thinking I should blow the water line with compressed air to see if anything is plugging the intake.
