Wow.Â* I don't see any value in owning one of those!
I assume it is because you are not in the 3d world where clanged up
stuff like this is popular but he does seem to be moving right along
in a smoky sort of way.

It's a very narrow boat for that speed and three guys who could shift
the weight quickly.Â* The speed is impressive but very dangerous.

Seeing that contraption running, it occurs to me danger is not their
first concern. I guess there are rednecks everywhere.

I am impressed with the ingenuity a bit. I assume this thing is raw
water cooled so it might not last long but it is a cool ride while it
lasts. It would be interesting to see how they are getting the water
pump primed to get going. There is nowhere enough detail in that
video.

All of the raw water pumps that I'm familiar with are self priming,
typically with flexible rubber/neoprene vanes and positive
displacement.

That is a marine water pump, This is an Izuzu Diesel. It assumes a
radiator with water above the pump.
