Prop Speed

[Walter P]

A while back I recall some discussion regarding a preperation for the metal underwater components which I think is called Prop Speed. A couple of guys at the boat yard claim to have had wonderful results with it. Does anyone on this forum have any experience or knowledge about the product. Besides the material cost (which I have been quoted approx $400.00 for a small container), the labor for preparing the metal is time consuming and therefore very expensive. The yard cost for them to do the job is about 2 or 3 boat bucks. This is only for the metal parts.

We have had very good success with Prop Speed and will be reapplying it to shafts, struts, and rudders in about a month.

Thanks Paul, I read the link as you posted it and am impressed. Sounds like it's worth the cost and effort.

I'm a propspeed user also, it's not perfect but as good you can get for running gear. $400 for materials sounds a little high, I spent $425 for the completed job on my 36.

I did the propspeed thing 2.5 years ago on a planned haul out. It didn't last very long. Then it was finger pointing between the yard and PS folks. Last haul out I went back to the "Tri-lux recipe". It's holding up much better.

A buddy of mine with a 48 Ocean, just tried something called "mussell guard" or something mussell. They way I understand it, it's either a powder coating or some typ of "baked on" finish. Props only. I was under his boat yesterday and looks like it's holding up pretty well. Thx.

$425 for the "large" size which the yard claims is minimum for my underwater metal including props, shafts, rudders, trim tabs, struts and all metal covers etc over each through hull opening. I don't think that doing props only is of much value, but I suppose it's better than nothing. Perhaps someone has a better source?

As far as going back to the old materials because of dissatisfaction with Propspeed, what happened to cause you to be unhappy? Did you follow the manufacturers instructions perfectly?

When you look at coatings for running gear or props it's more a function of getting the coating (whatever it is) to stay on than it is the coating itself. Failure of a product is almost always because it came off not because because the coating itself fouled. The very best way is sandblasting anything else is hit or miss. Your probably better off spending your time and money on the preperation than on the coating.

I'm in FL and have had good results with sandblasting and epoxy coating followed by hard antifouling on running gear all coatings should be sprayed. I have never been able to get anything to stay on the props. Mussel Buster is a powder coating process I haven't tried that but if the props are blasted prior to aplication it may work.
