What is this warning lamp / buzzer for?

[Peter Reynolds]

Hi,I cannot tell what the middle of 3 warning indicators means on my Yanmar engine panel.I presume one is over heat, the other oil pressure. It wnet off today and I shut down the engine.Thanks,Peter

Warning Lamps

Two of these should come on when you turn on the key, before starting the engine. The oil pressure and alt. lamps should light. The hot light should not. Some included the link to the Yanmar panels, so that should tell you which is which.

Water alarm

Thanks all,I did get on my hands and knees and actually look at the panel. It indicates water. There must have been some seaweed or something blocking the water flow causing an overheat alarm.Seems to be fine now ran it for 15 minutes yesterday.Peter
