regarding copper coating a bronze prop.... doesnt a bronze prop already have a higher copper content than bottom paint?
I once had a fixed 3 blade coated with aircraft teflon coating (used in the sliding anti icing componants of the wing) just like the frying pan stuff but tan in color. It worked pretty good for 6 months then I sold the boat... was coming off on the tips though...

boat has just been hauled and not too bad a growth using the lanocate.
Have cleaned the prop up and forked out $100 for the prop speed. Be interesting to see how that goes.

- - Because it is expensive, wears off and sets up a wonderful battery condition to the other parts of your engine system. You might want to isolate your prop shaft from the engine with a "drivesaver" Drivesaver Marine Couplers
- - I have heard good results from folks with the hyper expensive "Prop-speed" paint system. But I have tried everything but that and nothing has worked except totally polluted harbors like Chagaraumas Bay when nothing can live in those waters.

If I'm going to be anchored for over a week or so, I dive down and tie a plastic garbage bag over the prop. When I take it off, the prop is clean. It's a lot quicker and easier than scraping.

I have done the same for many years - works particularly well for folding/feathering props...

that magic marker stuff appears to have worked - at least for the past four months.

i live in an area where barnacles on props are a serious problem - east central florida. i used to dive on the prop once a month, as do most other boat owners around here. when i did the bottom four months ago i decided to try that magic marker stuff.

i used a 'sharpie magnum' black marker. one for each of the three blades on a 17x12 bronze prop. the boat has been in the water for four months now and i've only had to scrape four barnacles off it.

like the man who jumped off the empire state building said as he passed the 86th floor, 'so far, so good'......

, your trick is very smart, and original in my opinion. A question though: If you need to depart in a hurry, or forget the plastic bag while starting to move what would happen?

I do the same thing particularly when we're not cruising. I always put a piece of tape over the ignition switches and write "bags" on the tapes so I don't try to start engine without the bags coming off.

I tried a new trick this year that works well. I have saildrives with folding props and if I use 2 plastic sandbags, I can cover the prop and saildrive at the same time. When I want to use the boat, it's much quicker to take off the bags than scrape 2 props and 2 saildrives.

For what it is worth - I was involved in the selling of a Hartley 32 RORC that had been untouched in the water for 3 years. (Owner bought a bigger boat and headed out into the Pacific) The growth was phenomenal - weed, mussels, barnacles - you name it. The prop had been heated at the last slipping and plain lanolin grease (from the chemist) applied. When I slipped the boat there was no, repeat no, growth on the prop at all. I was very impressed. I do the same to my prop now - I don't get growth - but then I slip twice a year once to antifoul - once to scrub.

I like that bag trick! I once had a fixed 3 blade coated with teflon (left over aerospace variety teflon) Unfortunatly it didnt get a real good test as I was in the PacNW, which is pretty barnakle neutral. I noticed the teflon disappeared from the outer edge 3/8" of the blades due to cavitation no doubt. I tried rubbing lanolin on my Catamaran props in Trinidad. It seemed to work as well as bottom paint does. I sprayed a whole can of silicone spray on a prop once also, it seemed to work about as well as bottom paint also.

Post I have to try the Egg White!

The YOT is on the hard now getting a new bottom. I applied bottom paint on last haul 5 years ago and prop wasn't to bad, but I generally give it quick scrub a couple of times a month.

I've removed all the paint from the bronze prop an will coat it with egg whites and report back.

It has to be done!

Cheers
