All of a sudden, my Universal M3-20B is repeatedly stopping. Happened yesterday for first time while underway. Was able to restart right away but kept stopping suddenly after a few minutes. Just sputtered and died.
Was able to get back into the slip by repeatedly restarting. Guessed it was something to do with fuel
system. Primary filter looked ok. Replaced secondary, bled the system, and verified that the lift
Ran the engine
at the dock
30 min to ensure it all looked ok. Got out of the channel and raised the sails
and it died again. After the sail, made my way back by starting it over and over.
Other symptoms/issues: I believe I have a bad oil
pressure sensor with a high reading (even before cranking). Also on way in today noticed a lot more vibration than normal.
Temp is ok. Water
circulating fine. Plenty of oil
Looking for ideas.
