It could be low oil level or the overheat sensor may be dodgy. It cold even be that the alarm wire is diconnected and earthing out somewhere. Do you have the yamaha LCD dash?

Is the loom on your 703 box compatible with all Yams?

Back in the '90s, some Soozooks used the same plug connector with different pin/cable positions.

Nah, it wasn't deep enough to cover the water inlets, so the impeller was pumping air.
