my 50HP 4 Stroke with roughly 100 hours on it occasionally will have an audible alarm sound. This occurs at idle RPMs (it is on a pontoon and we do putz around quite a bit). Shutting it off and restarting resets the alarm and it will quit only to recur later. This has yet to occur at a higher RPM.
Oil is full. Water stream is solid and constant. Fuel is mostly fresh and conditioned with Stabil though I cannot swear the marina put Stabil in the fuel when they put it away for the winter. I added 10 gallons fresh fuel a few weeks ago. Power is good at all RPM. Runs smooth and quiet. No smoke or hesitation. I do not have an oil pressure guage or warning indicator. Nothing lights up on the council but I do not believe there is anything to light up.
I did scrub the lower end to remove any debris that may have attached over the winter. I have not tried it since doing so.
