I have to double check what year the outboard is but last trip out the alarm started going off. It's an older (90's I assume)
2 stroke. I will find out the exact year as soon as I can.

After some preliminary research all I could find was that the alarm is either temperature or oil related?

I've never owned an outboard before. Any place I should check first? It seems to run great, pump water like a horse and has never felt hot. The alarm doesn't go off all the time and seems to go away once I get on plane.

Thanks in advance for any help.
