Paul:

Any chance one of those custom water pump castings is still available? They
were made before I came on scene. In my set up on the Falconar the thrust
line is quite high and I have had to lower the engine a bit to make it all
fit. Also reducing weight is always helpfull.  I have been trying to figure
out an after market remote water pump but don't really want to go electric
either and have not found a suitable belt drive unit.

I'll check at the hangar Michael. I might have one or two left.
