History of the speedmaster drive?

[T2x]

The OMC Stinger was an interesting drive as well.... Unfortunately I didn't get to work on any...

OMC also had that two cycle drive where they laid a V4 outboard powerhead horizontally inside the boat and hung a sterndrive off the back. The whole thing passed through a big rubber bladder on the transom and when you trimmed it the entire assembly pivoted on the forward motor mounts. ( Later, after a few thousand leaks, I think they actually trimmed the sterndrive alone and at one point I believe they also had an option that rotated the sterndrive so it stuck up behind the boat with the nosecone facing the back seat passengers).It had the electric shift lower unit from the outboards and the only ones I ever saw were installed in boats manufactured by OMC ("The Evinrude boat" a pretty sort of gull wing hull and the "Johnson Boat" aka "The OMC Boat" which was a sort of trimaran/hydro design ala Custom Craft, which was nowhere near as fast as you might imagine).

Rube Goldberg apparently lived in Waukegan for a while.
