Mercury 90 ELPT Oil Tank Leak.
I have a 1998 Mercury 90 ELPT 2 stroke, the oil tank for the autolube is an integral part of the engine. The tank has the filler neck and cap as it should but also there is a small open hole at the top of the tank at the back of the engine. I think when I filled the tank up and trailed it to the water with the engine tilted oil must have leaked out as around the oil tank, inside the cowling and around the transom of the boat is now very oily. Should there ba some sort of pipe etc fitted in this hole or should it be blocked off. Surely the tank needs some sort of vent to atmosphere though??
Sorry don't know how to add pictures.
