Never heard of prop speed or the several other clones?
Amazing. (-;

Looking at the pics, why?
I see no barnakles, apart from having blown the antifoul looks pretty good.

Though on closet inspection, a few pink spots, electrical issues? To many anodes perhaps?

We have used Prop Speed on our boats, which a used primarily in the Chesapeake, with very satisfactory results. It is a covering that must be applied in accordance with the manufacturers instructions. We usually have little to no growth in the running gear and what does attach itself to the props can easily be scrapped off with a plastic scrapper without damage to the coating.

I had the yard coat the prop with Propspeed. It lasted about a month until it was all worn off. Not worth it to me.

I believe Prop Speed is a 2-part application. with a min-max time between coatings, 3 minutes or so and it is temperature sensitive. If this time frame was not followed, the coating will fail. That is likely the issue David experienced as it is not unusual for a boat yard employee to apply the 1st coat, move on to another job and return to apply the 2nd coat in 2 hours, or the next day. We had that happen once and discussed that with the yard owner when we had an issue later that summer.

MV CLASSEA has had PropSpeed applied the last 2 times she have her bottom painted, the picture attached was after 3 years the 1st time used . . . Because our trawlers donít turn the RPMís planning vessels turn, the product stays on longer and therefore, IMPO, is worth it . . . I does have to be applied properly.Click image for larger version

If you you hadn’t noticed any performance loss, I wouldn’t. Given where you boat, cold water, I would clean, epoxy primer the prop/rudder and then paint with bottom paint. It’s not a perfect fix but for the cost would beat the PropSpeed.

A small kit of PropSpeed for a 12”-24” prop is ~$300 plus maybe 2 more for the rudder. Add the cost of the meticulous prep and application, it’s not a cheap project.

i put it on a prop i sent out to the shop for repair, as when i got it back it was in perfect condition to apply it. haven't done enough time/hours to judge whether or not it holds up. i used prop glide. it's easy enough to apply but as has been mentioned, you need to follow the directions to the letter. it an interesting finish, and i think it should work very well as long as it holds on.

Magna, I've had reasonable results with Petit prop coat, 18/24 months between recoating.
Easier to do than Pspeed, a lot less $$, lasts a lot longer than simple spray galv, but good prep/weather is still important. I used two spray cans, thin coats.

I'd stay with bottom paint on the rudder, ask a guru in your boat yard about whether your boat is over-zinced.

My props and running gear have the Petit prop coat on Sb and Micron CSC on Pt.
In the spring, when I normally haul and renew whatever I am using, my haulout didn't happen. I did have a diver scrape the hard growth off the running gear, scrub the soft growth off the hull and renew zincs.
Saturday, Oct 30) I returned the boat from Saltspring to Coal Harbour. I couldn't get full revs Stb due to barnacles. Got full revs Pt, but still needed to scrub soot from the transom on arrival. This tells me that both sides are crusted with barnacles but Stb is much worse than Pt. Haulout will again be scheduled for the early spring. Hopefully this one will not be cancelled or delayed due to Covid.

I have not used PS, but I had the opportunity some time ago to wander amongst the charter fishing and other large boats pulled out for a hurricane and set cheek by jowl in the local boatyard. I am guessing I looked carefully at over fifty boat bottoms, most with PS applied. If as evidenced by waterline growth, the boat had sat a lot, barnacles were evident on the PS coated running gear. The hard run charter fishermen were universally clean with PS intact.

Those pink spots on the prop need some addressing. Maybe a good barrier coat before antifoul paint will help isolate the blades. Copper-based antifoul applied directly to a bronze prop is asking for it.

If your Propspeed only stayed on a month, you have an issue with the yard that applied it, not the product. It has been on my prop for 3 years, and looks like the day they did it. Prop has run about 600 hours in that time.

Absolutely. The key to propspeed is the application. We do use it and are very pleased with it. Just bottom cleaner wipes gently. As we are interested in maintaining performance and speed, we are the target customer.

Yeah, those manufacturing instructions also have tight tolerance. The yard we use had a lot of problems and now recommends Coval as an alternative. Correctly applied in the right environmental conditions prop speeds works great.

Right now we have had Coval on for almost two years and it wasn't until the last dive on the boat last month did our diver mention hard growth starting to build up that needed to be scraped and that was after a very warm summer season as well.

YMMV

It is a paint for the running gear. Application is critical as to how it is done.
