Good news! My engine was FINALLY returned! After four months lost in the limbo of international business. So I was able to build the new engine compartment and mount the engine (at least temporarily).
I build the mount step by step, making sure the angles were right at each step. The interlocking parts help reduce the possibility of errors but even so 1 or 2 degrees of movement is possible and that would be unacceptable. So here it is all trued up, epoxied to the frame, the the RC91cd sitting proudly in the bow of my "boat."
