Over the winter I did the following:
1) replaced the entire water pump: housing, impeller, wear plate, etc..
2) resealed lower units
3) verified the no oil alarm by running the engine(s) on 50:1 mix and disconnecting the oil line, both (twin engines) alarms sounded appropriately (short consistent beeps).....then re-connected the oil lines, no alarms sounded as expected.
4) Replaced primer bulb on stb engine, tested briefly all seemed OK.
Recently started both engines, water pressure ~10psi @ idle. Engine start easily and seem to run/idle well........however the stb engine sounds an alarm intermittently....not the rate of a no oil alarm, low oil sensors have been disconnected, stays on between 1-3 sec.......no cyclical repetition.
Definitely getting oil (blue exhaust).
Getting close to launching for the season......no have a concern.
Plan on measuring the temp of the cylinder head......thinking possible over temp(?) but have good water pressure. Fuel restriction problem (alarm does sound after revving in neutral).
Any other ideas?
If I can't find anything plan on launching......maybe need to run more oil/fuel through this engine.
Also....oil prime bulbs are rock solid.
