High pitch alarm went off on my Riviera

by Brad
(Australia)

2 weeks ago an alarm went off from the starboard cluster of gauges on my 35 ft Riviera. I shut both 454 petrol motors down to be safe.

I started both motors again after a short 15 minute wait and the starboard motor set off the alarm again.

I had good oil pressure and the motor was NOT hot.

Any ideas of where to look!!!!
