I am still working on this. I started making an extended transom housing, as I couldn't get one that would fit properly. I should be ready to set the engine in this coming weekend. I have been chasing down parts, more than working on it. But it is starting to come together now.
Here is an original Berk housing before undergoing "surgery".
