It's been awhile since I have been on the list. However, I thought I would
update how my Judson SC has been running. The unit has approx. 3000 miles on
it and is still performing very well. I have been adding 1 oz of Miracle to 1
gal of gas. Not having any overheating issues.

The unit has Torlon 4435 bladesB The housing bore treatedB with ECAT's thin
film wear resistant coating ZN54. The specs on the coating are 3000
microhardness , .06 coefficient of friction, 2-5 microns coating thickness,
1560 F max. working temperature.B 

One of these days I plan to tear it down to see how the inside is wearing. I
think a good point would be 5000 miles.


Merry Christmas

When I had my Judson I contemplated coating the inside surface with Teflon
or Ceramic or something to help with friction.
Never got around to doing it, though.
