I'm new here, thanks in advance for the help! I purchased a 2019 Glastron GTDW last spring, love the boat! I put fresh gear oil in the out drive because I noticed what I thought was a leaking drain plug. Turns out oil is pooling in the exhaust port on the back of the stern drive; it's a forward drive model. And there is a small drain hole on that back of that stern drive exhaust port and the oil was seeping out there and running down onto the drain plug. I'm assuming there is rubber gasket on the back side of the plate that is inside that exhaust port. Has anyone else had this problem? The picture is basically upside down but you can see that plate with the center lug and two side bolts. Any ideas?

While not familiar with the forward drive, I would suspect based on what you state that the O rings on the drain screw needs replaced. I would try that first before tearing too far into it. Might be a cheap fix.
