Pettit Zinc Coat Barnacle Barrier - Report

T37Chef · #1 (**permalink**) 09-26-2010

FWIW, I also thought I would post results of 5 months in the water using Pettits Zinc Coat Barnacle Barrier on the propeller and shaft. But first a few notes; I've used this stuff for the past 5 years with very good results, but this year, not good as you can see, although the prop faired pretty well, the shaft did not.

BTW, the only thing different from past years is the new shaft is made of Stainless Steel vs. the previous one made of Bronze, and yes, I did follow the manufactures directions

Anyway, here are some pics showing the poor results;

I had bad results also (LI Sound). I also think the extreme heat this summer didn't help and accelerated the growth of barnacles, etc. Think I'm going to pony up for Prop Speed next year... oh yeah, and sail more

I had really bad growth this year too using the same product. Barnacles on the prop and shaft were terrible, but also lots of slime on the hull as it was second year on the ablative. It seemed a bad year for growth with all the hot weather. The water in our creek was well above 80 for most of the summer. I hauled and cleaned it in mid July thinking that the worst of the barnacles were behind me but checked it again a couple of weeks ago in the water and had new growth again- a banner year. Nothing like swimming with the jelly's cleaning the prop. Our creek was so warm this year that I dont think anything could have stopped it (except for me sailing the boat a lot more). Lots of boats at our yard with the same problem.

I wonder what Pettit would say, sent email today.

I'm looking forward to hauling the boat in a few weeks and see what my running gear looks like.
The previous owner used Pettit and swears by it. The boat went in the water in late April and I have only lost about 150 RPM's.
I'll take pictures.

I used petit on the prop and found that I could scrub lightly with one of those sponges with the harder green side. That made the barnicles come right off.
