Lanolin as Propeller Antifoul

Hi there,
I have been told to use lanolin (sheep grease) as an anti fouling product on my brass propeller. The propeller will need to be cleaned , then heated and at that point the lanolin is applied. Has anybody any experience at this ?
thanks Ray

Re: Lanolin as propeller antifoul

As long as the prop never moves, it might last a week or two.

Tell whomever suggested that you have some magic dust for sale.

Are you speaking from experience or......? My experience has been totally different. I have used Lanocote prop and bottom which is a lanolin based product and applied it in the manner the OP described. I have found it lasts about 5 or 6 months and I am a full time cruiser. They advertise it can be applied underwater, but to do so the metal must be scrubbed clean with something like a scotch bright pad. If it has any slime or anything else on it it will not stick to the metal under water. If you have not gotten a spot completely clean it will quickly become obvious. Also you don't get a nice thin even coat like you do with heating the metal out of the water. Also your hands will smell like the north end of a southbound sheep for a couple of days.

Re: Lanolin as propeller antifoul

Two words. Sex Wax.

Our bottom cleaning diver put us on to this. In east central florida we have serious prop fouling. In the summer I have to dive and scrape the prop every few weeks. He told me to just rub Sex Wax on, that he's had other boaters do it with great success. I dove (snorkled) on the prop, cleaned it, and rubbed a heavy coating on. It works.

And where can you get Sex Wax? Any surfer shop. Its used to wax surfboards. Or online. I paid $2 for a soap bar sized cake.

Re: Lanolin as propeller antifoul

I have used the Lanolin trick it lasted about 6 months. Its not the type you get in a little pink tube for your baby's bottom. Its the industrial strength goopy stuff, the heat is important because this stuff is too thick to use cold.

Gonna get me some SexWax and try it too...

Re: Lanolin as propeller antifoul

Here's a source for pure lanolin. Same stuff as industrial but more highly refined and doesn't have the smell.

Didn't work for me on my plastic dinghy, didn't bother to try it on the prop.

Re: Lanolin as propeller antifoul

I used lanacote on my prop and shaft the prop remains clean but the shaft still got fouled. I applied it under water. Another valiant owner left one blade untreated and the difference was visible quickly. It has been suggested that if you are not using your boat regularly the lanolin just feeds the barnacles but if the prop spins regularly they dont stay attached
Cheers Ian

Re: Lanolin as propeller antifoul

A kiwi asking questions about lanolin! Must be an imposter.
Where I moor, the growth of fouling on the propeller is astonishing. I routinely apply a smear of lanolin when it is cleaned ie every few weeks. This is done in the water so I have not tried heating first. Not sure that it retards growth, may even encourage it, but it makes it much easier to scrape the critters off next time around.
Have also tried winch grease when the lanolin could not be found. This seemed to work better at reducing growth and still made it easy to clean but a bit more expensive.
Have not tried sex wax. I have a block of Mrs Palmers in my board bag (I do a lot of single handing). I will give this a try next time and report back.
Carry on
Dave

Re: Lanolin as propeller antifoul

I tried lanolin on one of my Cats Max props. The other had bottom paint brushed on. The Lanolin was at least as good. I didn't heat it, just rubbed it on in a circular manner... Neither lasted very long in the tropics though.... Lanolin may be harder for Barnacles to cling to though... you can paint your prop with bottom paint, but that doesn't prevent barnacles.. they just attach themselves, grow and then die... which leaves you with a prop problem anyway!

Re: Lanolin as propeller antifoul

Lots of cruisers have had good luck with Rust-Oleum Flat Gray Cold Galvanizing spray paint.

It worked much better than the expensive Lanocote prop and bottom

Re: Lanolin as propeller antifoul

When I bought my first boat in 1984 all the mags said to put lanolin on the rigging ends (swages) etc etc. I got a tub from the pharmacy and still use it today for most everything. The best use is on shackles. Even after a year in the water (on mooring tires) the shackles are easy to undo. Better than grease as it seems to stay on. And it does wonders for your hands! The lanolin in pharmacies is what they use as a base for ointments. I guess it's medicinal quality.

Re: Lanolin as propeller antifoul

Hi Everybody
Thanks for all your reply's. I use lanolin on all my yacht electrical fittings,shackles, anchor and anything else it might possibly help with. Lanolin is fantastic , keeps everything its used on from seizing and corroding. Boats and lanolin are the best of friends.
But if anybody else has anything to say about the prop-lanolin debate it would be greatly appreciated.....
