Nano-tech Experiment #2: Initial Observations

Looks like silver, doesn't it?
 I've tried out the nano-tech superhydrophobic coated prop on our thundering 3 HP dinghy motor.  Here are some initial observations:
  • The air film is retained when the prop is completely submerged.  As the picture shows, it makes the prop look like it is made of silver.
  • The prop does not cavitate due to the retained air film
  • The film of air remained intact over a half-dozen trips to shore and a day of submersion.  Perhaps it is maintained by gases captured from the exhaust, or perhaps the air is simply retained well enough to withstand the surface turbulence.
