Some very interesting ideas here. I applaud anyone who works to preserve the look of a classic transom! I need an engine where I sail, and I must admit that one of the main reasons I passed on buying a particular boat years ago (a Cape Dory Typhoon) was that I just couldn't bear the thought of how an outboard looked hanging off that sweet Alberg design.
CnC, you and I differ on the desireability of an inboard engine, but I salute your ingenuity and sensibility in developing this solution. +1 to you sir.
