Hello all-
many thanks to the forum especially UFM82 for the help thus far.
Had an issue come up yesterday and have been doing some digging to resolve.
Mercury 175 S/N OD030309
Running around the SeaRay 190 yesterday when the continuous beep beep beep started. I understand this is an oil injection alarm vs the temperature continuous beeeeeeeeep.
I stopped and checked the oil reservoir under the cowl and it was full. I loosened the cap and oil started to overflow out. Engine was running fine when the beep beep alarm sounded. I restarted the engine and the continuous beep beep started immediately after starting. Drove the boat home immediately without issue other than the alarm. Still ran fine with some blue smoke in the startup exhaust etc.
Today following some research I checked out and tested the following.
all of these were with the motor running
1 After visual inspection of the float on the cap I disconnected the blue wire from the oil res cap under the cowl. Still beeping while running- assume the float sensor is still good
2 Reconnected blue cap wire. Disconnected green wire from alarm module at the coil wire terminal. Still beeping while running
3 Reconnected green wire and disconnected the white & blue/white wires from the pump rotation sensor. Still beeping while running
4 Left those disconnected and then also disconnected the green wire from the alarm module at the coil terminal. BEEPING STOPPED
My conclusion is currently the following.
The alarm module is good because it stopped beeping described above.
The oil cap level sensor is good.
The cylinder spark is not the issue as the engine is running well.
I suspect the rotational sensor at the pump or the pump is failing and not spinning consistently???
I would love some insight of the forum members on if you agree with what I’ve done and concluded. What would be the next steps you would pursue?
I know I know I should just premix...and likely will.
thanks again
