Thought someone might like this.
I found this engine last fall, lying in a field and stuck. It had been removed from an African Queen-style wooden launch built in 1967. The engine was scratch-built to fit the launch, which by last fall had rotted away and been burned. I managed to retrieve the engine, the rudder, and the drive shaft with a propeller that looks just like the one in the movie ("..wouldn't it be better to weld it on? Isn't that the right word, dear? Weld it on?")
It took about five minutes to get this thing un-stuck and running on air....
