|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.
