I have a 2010 mercury 150hp outboard oil injection
i have a large oil tank on the boat and a small oil reservoir on the engine block. My small oil reservoir is always empty should it be?

The small tank is an intermediate.

The large tank feeds the small.

Check for plugged filter in bottom of large tank or a leak in the line running between the two tanks.

If the large tank feeds the small tank then the small tank should have oil in it?
Engine tank should always be full...check for leaks in air line,hose kinks and blockages in boatside tank
