Really, the question was....... can I run a pre-Alpha with no water pump.
The closed cooling seems to have an engine driven raw water pump sucking
through the hull. From the consensus here seems like I don't need to bother
about it. I had been worried about the stern unit being cooled but I suppose
it is pretty well submersed in the lake water anyway...

I tend to agree with you, what is your concern or question ?

I would suspect that you may not find a water pump impeller either.

Yes, the outdrive is cooled by being in the water. The water pump is
to supply cooling water to the engine, not the drive. Some people add
a drive shower for cooling the upper bearings in performance
applications but that would not be your situation.
