Prop Speed Propeller treatment question

Has anyone used Prop Speed propeller treatment to keep barnacles off of the prop and shaft? Nothing seems to keep my prop clean and free of marine growth. Does this stuff really work? It is VERY VERY expensive - but so is paying divers or marina lift-out fees!

A marina near Baltimore is offering a free application of Prop Speed when you have your boat hauled out for winter storage.

They charge $75.00 to clean and prep the prop and they will apply the PropSpeed for free.

Considering how expensive PropSpeed is and the fact that I would have to sand or wire brush the prop even if I bought the stuff, it sounds like I would only be out $75.00 if the stuff does not work.

Try Pettit zinc coat barnacle barrier, it has always worked for me.

Certified...in several regards...

When I haul in the spring, I will apply another coat of Prop Speed.

For more than 2 years it kept my prop clean. I'm having to scrape it now, because it's no longer there, but for the first two years, it slung everything just as it was supposed to. As it aged, all it took was a swipe with a 3M light pad.

I wouldn't use anything else, because I don't haul frequently...

YMMV but I'm VERY happy with it.

the charm of it.

Whether you get away, or whether you don't; whether you arrive at your
destination or whether you reach somewhere else, or whether you never get
anywhere at all, you're always busy, and you never do anything in
particular; and when you've done it there's always something else to do, and
you can do it if you like, but you'd much better not."

I've used it for a couple of seasons. In northern waters it worked very well. In the Caribbean it wasn't quite as effective, but was still much better than my previous treatment -- nothing!

I've seen props of big power boats that are very clean on hauling....my luck wasn't as good, but I attribute some of that to the application. I think the application last year was imperfect -- the two part primer has to be followed immediately by the one part final coat. The yard that applied it assigned one guy to the job and he wasn't working at light speed. I'll give it another try this year and will do the application myself with plenty of help so that the final coat goes on quick!

The deal the yard is offering sounds pretty good to me. My guess is that it will save you a dive or two. Go for it.

PropSpeed

Thanks everyone for the help with my Propspeed question.

Is the Pettit paint nothing more than old fashioned “Cold Galvanizing” zinc-rich paint?

If so, you can buy zinc spray paint at Walmart, with no need to buy the high priced marine brand? Or does the marine brand have a more water resistant vehicle allowing it to adhere to the underwater gear better?

Considering the expense of travelift haul-outs – it looks like PropSpeed is the better value in the long run because everyone is saying it lasts about 2 years.

Because my marina is offering a free coating of PropSpeed with winter haul-out and storage, and not one negative reply as to how everyone likes the product – it is a no-brainer – I am going to have my marina apply my free coating of Propspeed to my prop, shaft, and through hulls.

Prop? Yes. Shaft? Dunno.. I guess so.. never checked.. not sure I would myself. Through-hulls? No. Anti-fouling goes on through-hulls.

As an option to Prop Speed I used plain lanolin smeared on all the running gear this past spring. We keep the bnoat in Baltimore Inner Harbor and just had a diver clean the bottom. He stated the prop blades were clean without signs of a single barnacle. There were barnacles on the hub of the prop and shaft so I'll add a bit more prior to spring launch. A cheap alternative to Prop Speed.

Yeah I'd agree. Only on the prop. I have used it for years in the tropics. If it applied properly, it is perfect.
