Alarm beeping on mercury efi 150 outboard.

I could never figure it out for sure myself. I loosened the cap on the motor oil tank and started the engine with the ears and water on it. The oil did not ease up out of the tank after a minute or so. I shut it down and looked over the lines and other big oil tank. Looked over the oiling system for visible problems with nothing found (couldn't be that easy). I took the boat to my dealer and they called and said it was the oil sending unit. The older you get the more you know as the saying goes, but most knowledge comes with a price tag for sure. Check Australia Post Catalogue and Jaycar Catalogue.

This fixed the problem?? I'm having the same problem with mine. Thought it was something with the water pump. Already dropped enough money. Trying to get to the bottom of it. Any help is greatly app. How much was the oil sending unit??
