I've heard nothing but great reports about this stuff:
http://www.propspeed.com/. I plan to use it at my next bottom job.

Ed: You can overzinc a wooden boat, causing the wood to fail at
thru-hulls, but i've never heard of it happening on a plastic boat.

Da Kine, I'm on Cape Cod. However, the water gets pretty warm for a
couple of months. I've heard of cyan peper working. Thanks for the
tip.

Ed, The guy that said something about being over zinked. Seemed to
think that a small amount of electrosis might help with barnacles. As
far as the terms of physics, I couldn't venture a guess. And the Cape
Codder who told me that would be insulted if I asked him to explain the
precise terms of physics that would back up his notion. ??

Keith, I'll check that site. Thanks for the tip.

We were told not to zinc the shaft for that reason, but I was always too
chicken to trust it. Right now, our shaft and prop are completely
isolated electrically from the rest of the boat: rubber drive saver to
the transmission, strut not bonded. The only problem is that it's a
bronze prop and stainless shaft. We lose half a zinc every year. When we
switched to a MaxProp, we started losing half of *both* zincs each
season.

Oh, and the growth is incredible, no matter what I do or don't do to the
prop.

I'm half tempted to switch back to a bronze shaft.

Keith, Propspeed sounds like the way I'm going to go. Have you priced
it out yet? What do you think it would cost to do 2' of shaft and a
prop. Thank, Paul
