I really wanted to do a story on that. Sorry he's gone now.

Yes, sort of.. They cam from Rick Kirk's RK Machine shop. None of them are boat motors. There was only 1 actual boat motor and it was removed from the boat and ended up in Rick's personal museum in Riply, OK. In the same museum, there was another "boat motor" that was all black & built for shows by MerCruiser. This engine was never in a boat. It was a mock-up, incomplete internally, to reduce weight for transporting and had a stern drive unit attached.

Insofar as the source & makeup of the other engines in this lot, Graham responded to a thread on this same subject, on Facebook/ZR-1 Net Registry Group. He is one of only a few people who were at Mercury and in a position to know.

Here is a quote.

"If i were to hazard a "guess" i would say they were a mixture of re-built cam seizure engines, which would have a VIN stamp, line rejects, service returns and a conglomeration of parts left over at the end of production."
