i was first thinking of using vaseline or something equal but i thought after a while of spinning on the shaft underwater it would wear off quickly. thanks for the info on it. i think i'll try the paint and then vaseline this spring.

W..I have been using it on the saildrive successfully. up to 6 months no barnac;es or some really small ones..but they come off really easy.

Still, even if only delays 3 days it is 3 days less...

This year we tried the prop, because it rotates so much, and after 3 months, when I dove there was nothing there...

I think that even on rotating stuff it leaves a film...

Let's talk in december..I'll post the haulout for you.

I have used different brands of prop antifouling with very different results, Boero was very good almost 2 years and hardly any growth, Veneziani not even 1 season, Now I am into the second year with Velux and the prop is still very clean. But I'll try the vaseline coating before my next splashing, thanks for the advice Alex.

Nine years ago we moved our boat from a fresh water lake to the Chesapeake Bay. Mid summer we were motoring and the engine kept overheating. We phoned our diesel guy and he said "Bad year for barnacles-call the diver." Sure enough-after a good cleaning the engine ran fine.
We've never painted or used the vaseline trick. Does winch grease do the same thing as vaseline?

I've always painted my prop with the same paint I'm putting on the bottom. Never had a problem with it not staying on and barnacles haven't been a problem. Prop is a Martec folder.

My prop is a 3 blade Flexofold, described by the manufacturer as: Cast Nickel/Aluminum/Bronze (NIBRAL), high strength, corrosion resistant and 82% copper for anti-fouling. I am not sure the anti-fouling features is working because the prop has to be cleaned every 3 to 6 months to get rid of the barnacles otherwise the motoring speed drops by 1 knot. The boat is in the Med, sailed most days from April to November. Is this to be expected? Any solutions, including anti-fouling and vaseline?

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

You don't want to put paint on your MaxProp, take the paint off and apply the Pettit zinc cote to the prop, shaft and strut. Three coats and keep it out of the cutlass bearing.

The Pettit stuff works great...if you question my advice speak to the people at PYI PYI Inc. Max-Prop PSS Shaft Seal Seaview Radar Mounts R&D plus you can order the Pettit and a MaxProp grease kit while you are on the phone.
