"Water in sail drive seal alarm" Yanmar 3YM30

[DestinySoyQuick]

Started my engine up today on the Yanmar 3YM30 and was going to go sailing. However, an alarm is now going off, and the instrument panel shows the alarm lit up for "water in sail drive seal alarm." I'm wondering if anyone may have any insight into what this could be about? The engine is not a sail drive. It has a KM2P gearbox and prop shaft that goes through the hull. I am trying to trace wires and figure it out, but anyone have any ideas? I wonder if the previous owner wired this particular alarm into some system that I am unaware of or if there is something standard that I should be looking into. Any insight is much appreciated. Thank you! Sanna
