Lanolin Application

[Johnjo]

Hi all
Recently bought a new propeller, And spent a couple of hours polishing it, can now see
my face in it, yeh I know not a pretty sight!
Also bought myself a pot of Lanolin, So can someone please tell me the best way to apply it as
to get the best results out of it.
How many coats, whether to heat the prop etc. this kind of thing!
many thanks
mike

Per the posting <A target="_blank" HREF=http://www.ybw.com/cgi-bin/forums/showthreaded.pl?Cat=&Board=pbo&Number=318248&page=&view=&sb=&o=&vc=1#Post318248>here</A> a week or so back. I daubed it over the prop and then put a heat gun over it until it formed a sticky glaze.

Good luck

Splodge lumbs of lanolin over the prop, then using a blow torch or heat gun, melt it so that it forms a complete - fair - coating over the whole prop. don't be sparing.

Put the prop on first!

When she comes out (the boat that is) let us know how it worked and where you are.

Thanks for the advice, will certainly post the results when the boat is lifted out in
the autumn, we are on a swinging mooring on the upper reaches of the River Fal in Cornwall,
Lots of warm water, A sewage farm a couple of miles up river and plenty of farm run off.
A pretty lethal cocktail, ideal conditions for heavy fouling,
So the results should be interesting!

The result will be interesting - a fellow in our Marina has an Aquastar 34, just one year old. Before it went into the water when new, he coated the props with lanolin. When it came out recently (one year on), he was very disappointed to see them absolutley covered in very large barnacles, the worst he'd seen on any of his boats before. Seems it did not work in his case, but maybe he did not apply it properly in the first. To balance this, another with a similar boat felt his application had been successful in cutting down the normal accumulation.

Thanks Nicho
even if it is a failure it could not be a worse one than the prop/bootline antifoul
I used last year, 16 quid threw away! At least with the Lanolin its got a multitude of uses.

Rather than use a heat gun (which I don't have . . ) I just warmed the pot of Lanolin in hot water and squidged the warm sticky gloop on wi' me fingers. Quite easy, once you get used to its lack of 'spreadability'. Once it's cooled it's back to hard and tacky like dry Evostick.

First time for me too. Although I take responsibilty for my own actions, if the stuff bloomin' well attracts, rather than repels, barnacles I'm cancelling my subscription to ybw.com!!

Where did you get the Lanolin - local shop or anything that is online as well ?
Can't get the stuff in pure quality needed for 'our purpose'

thanks

I bought mine from Boots, but was told that only the larger stores keep it. I applied it back in November so will report when I alter the prop pitch soon (it's currently over-pitched).

I spread it all over the prop and used a heat gun to aid the process.

You can get the chemist's shop to get some for you but make sure that you get anhydrous lanolin, not the stuff the girls use when they are breast feeding!

www.classicmarine.co.uk - Lanocote is the product name.

Mike, I've just put a lanolin coating over my 2 blade folding prop - freshly polished ..... not the same pretty face through ......... and prop shaft.
Launched the boat last week in Port Solent, started the donk, engaged 1st and lots of 'bits' (I guess lanolin) were seen being swirled away in the prop wash.
I heated the bottle of lanolin so was pretty easy to apply, though messy, by hand. Maybe a blowtorch would help, but nonetheless, I'll let you know what state the prop is in when a) water is warm enough to dive b) get far enough south to dive or c) next winter - the latter I expect.
Also tried some dear prop antifoul last year which sort of half worked but very uneven.
The thing we do for fun ...... where does it end ?

I tried lanolin three seasons ago and it didn't prevent growth
(Long Island Sound New York - pretty similar to the Solent in being a somewhat enclosed body of water). The last two seasons I used a hard antifouling on the prop with better results.

G'day mike??
The coating of a prop with Lanolin is best done by placing the prop in the oven on about 180 degrees centigrade for about half an hour then painting the hot prop with the lanoline then back in the oven for about another twenty minutes this should impregnate the lanoline into the prop then let it cool and reinstall on the boat, the prop can then be applied under water if need be.

I word of warning though - if you don't use the boat at least twice a week then the lanoline doesn't work properly
