I recently purchased a used lower unit from a 1986 Force 125HP engine to replace my cracked lower unit on a 1990 90HP. When I purchased the lower unit, the oil drain plug at the bottom was not tightened all the way. I changed the oil and put the allen plug back in. I am wondering if there is a stop for that oil plug. It appears to continue to screw in deep into the unit. I am concerned that if I keep going it will run out of threads and end up inside my unit. Does anyone know if there is some sort of stop for the plug? Should the plug be flush with the unit or does it go deep into the unit? Thank you.
