Brief no oil alarm, intermittent

135 HO past couple trips has given me a brief no oil alarm, run half hour or so then bleeeeeeeep and starts to slow down then immediately picks back up and light goes away. Doesn't seem to come back on the same trip/run. Not really a problem but a bit of an annoyance. Checked the lines and everything I can see looks good no cracks. Do I need to pull that hose for full inspection or are there other possibilities such as bad sensor, etc? Engine and oil tank are close to 2 years old with 150 hours.

Possible air bubble on top of sender. Common with more current 60* engines.

 

Remove sender and slowly prime oil until steady stream. Catch oil in container. Fill sender (A few drops only needed) and show it home with continuing steady stream by hand primer . You may need a helper for the priming.

 

Lykke til!!

Another thing is to take apart the electrical connector from the oil pressure sensor and look for signs of oil residue. If there is any, the sensor may be leaking internally.

Thanks guys, I'll get on it. It's going to be a while before I can report back though, we've not been using this boat much so test run won't be any time soon.
