Prop anti-fouling question

[Clay Stalker]

Hi folks:
When I had an outboard motor in a well I used a tin-based (TBT) product from Tempo to anti-foul the lower unit of the outboard and the prop...worked quite well. I understand this stuff is no longer permitted for use in hull anti-fouling, but has anyone used it on their bronze props and shafts? Other than the obvious ecological issue, is there any reason why this would not be a good thing to use? Many thanks...Clay Stalker

TBT was outlawed for the same reason that DDT was. It's hell on the environment -- whether you put it on the hull or the prop or anyplace else in the water. It works great though. The old bottom paints only had 2 or 3 percent tributyltin (TBT) in them. Like lead in paint and voc in varnish they made wonderful products but was bad for us so we outlawed them. Paint stores sell it as an additive to house paint (where it won't get in the water) as an anti fungicide.
