Propeller anti-fouling?

Check the ingredients of that antifoul paint. If its ingredients include somethings like zinc or cadnium or nickle or magnesium or something with a negative potential, then they are simply trying to solve their anodic galvanic reaction which might be attracting the animals. Easier to solve with a rectifiar or battery issues. "Edgar" wrote in message ... "Bruce In Bangkok" wrote in message .. Has anyone tried any of the anti-fouling schemes intended for propellers, and if so what was your experience? The question comes about because I just had to dive on my prop and clean it. When I got down there I discovered a mass of "clams" as big as a bushel basket. Took two days to scrape them all off. True, for one reason or another, the boat hasn't moved in the better part of a year but still I don't believe I have ever seen as much growth. Must be either global warming or high CO2 content :-) In any event, it does make one think "there must be a better way". Cheers, Bruce (bruceinbangkokatgmaildotcom) Ordinary ablative antifouling might be better than nothing if you hardly use the boat but it washes off in no time at all if you run the engine. I use some expensive stuff in a spray can that Volvo produce for their underwater units. This seems basically to be the same sort of antifouling but harder, so it does not wash off so quickly. Also it makes a somewhat slick surface so that barnacles find it harder to stay on while the prop is running. I have a theory, not yet put to the test, that the very slick paint that has been produced to make a wall graffiti-proof would be the way to go because barnacles could not stick to it at all once the prop started to rotate.. The reason I have not yet tested this idea is because the smallest quantity that I have found for sale is about 10 gallons. I have tried everything and finally decided to use a plastic "Perfectpitch" prop. They provide a special puller so you can easily take the prop off to clean it. |
