If not lanolin, then...?

[MYStargazer]

Props cleaned. Even wet'n'dried to a virtually polished state.

Got no lanolin to hand.

Chemist (a boat owner) recomends yellow vaseline. Have a pot of marine grease on board...

Which to go for?? Any thoughts, folks? Thanks.

I'd just buy some lanolin ...

Save your money. Lanolin is a complete waste of time

I polished my prop and then put range black on it. It worked quite well. You can get it at any hardware shop, comes in a tube

Buy a mask and snorkel as well as some wire wool (or a stainless scouring pad), clean it off underwater, job done. Nothing else really works.

Just the sort of sarcy remark I'd have made. Top marks.

Well if it's lanolin you want to use, then get some. I use anhydrous lanolin both spray and grease on the boat for lots of things, but not on the prop. Here in Aus we tend to either just A/F it, or get the "propspeed" treatment. I'm now convinced the propspeed is the way to go, as at 12 months I've got growth, but it spins off at 800 prop rpm. Boat is 31 feet, displacement yacht, 22 hp, hullspeed 5.7 knots. The fast powerboat guys are using it too. Believe Hempells have it in trial kits, but must be applied as per directions. Lots of problems here until people wised up to following directions religiously.

any tips to making propspeed work? ie what is following instructions religiously. I've never tried it.

It comes in three times - primer, a coatings to hold the topcoat on, and the topcoat. Timing is critical, as is cleanliness. The topcoat is either silicon or some sort of ptfe - very slippery. I'm told it is damaged by people putting their grubby fingers on it though, so you'll always see the pros covering it with bubble wrap until just before launch.
There is also some temp range at which each coat goes on - don't know what it is as I'm paying to have mine done (actually same cost all up as me buying the kit and I get a warranty of sorts.)
BTW back to the A/F option - the same guys tell me if I use A/F, then I should coat the prop everytime I walk past it while I'm doing the boat, and aim for 10 or so coats, even if the time isn't adhered to. I've always used that technique in the past until I changed to propspeed with good results, altough only lasts 9 months or so in my area / climate.

Lanolin? Urban Myth. Dive mask and scraper, or better--go out sailing more often /forums/images/graemlins/smirk.gif
