Here's a Rhapsody picture above the strut mount taken from the port side looking aft. The original owner had the 3/4" shaft replaced by TPI with a 1" shaft and required that the strut be replaced. There are no seams around the interface, so unless you have a crack in the bottom, I doubt that is the source.

Here is a picture with the Yanmar removed so you can see the area where water can enter the liner area. What is more likely is that water is getting in the openings on either side, or entering the holes on the lip where the engine cover rests.
