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". Haven't tried it because I don't have a boat. But you made me think that if you knew your boat would be idle a long time, wrapping the prop it in a old piece of poly tarp might work. Maybe even a thick black garbage bag. Should be easier to put that on and crack/cut it away than spend 2 days scraping. Barnacles need some light to grow, right? We sometimes want a patch of lawn for garden and the easiest way to kill the grass is to lay something on it that blocks the light. --Vic Yes, putting a black garbage bag over the prop does cut down on growth drastically... however. As it was really happenstance that the boat wasn't taken out so no plans had been made for storing the boat and secondly, most people start the engine every week or so even if the boat is not being used. Inadvertently most of those who have taken the precaution to bag the prop seem to test the transmission when running the engine which sort of negates the whole project. (the bag rips).
