Low oil in Reservoir Fault

[Keith A]

Good evening,

I'm up here in Maine and just took my boat out for the first time since last fall. About halfway through the day I got a solid beeeeeep, and turned the outboard off. I checked my Vessel View mobile to see if it threw a code and it did for low oil in reservoir. I think I got another code for guardian mode. I made it back to the ramp, but my outboard was acting off power wise taking off(taking it easy), and when I got home just turning the key on without starting generated the same beeeeep. My oil in the boat tank was at least 3/4 full and the reservoir on the motor was at about half when I checked it on the water. I'm thinking this is supposed to be full to prevent air? I'm guessing where it not being in use for around 4 months is a clue? FYI, the tank in the boat is original to the boat, which is a 1998 model. Any help on checking things before I go out in the garage and waste time is appreciated.

Engine tank should be 100% full with no air space present.

See the FAQ Section "Bleeding air from the Engine-Mounted Oil Tank" provided you have at least 1.5" of oil in the engine-mounted tank. If oil level is LOW, you will need assistance to perform an oil pump prime.

Thanks for the advice! Boat tank pickup screen was clogged as well as pump that needed a new o ring as well(leaking). Boat was sitting unused for 4-5 months(Maine winter).

"Pump that needed a new O-ring"? What about the other 14 o-rings in there?

I've been hearing a lot of people with optimax/dfi oil gelling in the tank clogging the oil pickup. That was my issue when my engine alarm started going off about 30 seconds after I cranked the engine. It always went off after a few seconds though. My engine mounted oil tank would only fill halfway

One commonality among the many recent posts on this also includes a deck fill.

+1... though usually combined with some level of ignoring signs and warnings that a problem is there (NOT always, however).

Knock on oil drums... only problems I've seen locally were two that were water-induced (and really wouldn't matter WHAT oil it was running, water and oil don't mix very well).
