I'm having trouble finding the drain and check plugs on my Mercury 110 series 9.8 horsepower outboard. I had a Chrysler and found the plugs with no problems, but i cant find the plugs on the Mercury.

G'Day. The bottom plug would be similar to the Chrysley. On the starboard side under the lower unit. The top plug is much smaller found just above the cav plate on the stbd side.
