Another Propspeed question— I have conflicting advice

I get about 1 year out of Prop Speed, it gradually gets thinner until transparent.
Not a big deal as I use the boat once, sometimes twice a week, heavy growth only if a boat is not being used.
Having a diver clean the bottom every 6-8 weeks, he keeps bragging about my bottom paint, the Trinidad HD, 13 months so far and in great shape.
Previous coats were Trinidad Pro, 27 months.
Got 4 years on the Pro with a Sailboat I owned for 14 years.
Switched to aluminum anodes last year, they last longer in brackish waters, 13 months so far.
Never tried the zinc paint.

I leave the running gear bare and have a diver clean the bottom and gear once a month (miami, on the bay)

propspeed is expensive but the problem is that when maneuvering in shallow water it gets sandblasted away in no time. I can see the benefits for like a sportfish which runs at fairly high speed to and from the fishing grounds and rarely operates in shallow water. Otherwise not worth it especially if most of run time is at hull speed.

even when anchoring in the Bahamas we stir a lot of sand

I've been using PropSpeed for 15+ years. I've only ever had one problem, and it was a prep/application issue. Great stuff, and I can't imagine having a fixed-running-gear boat without it.

Is there any special way divers should clean propspeed Props? Or things they shouldn't do?

If it's doing it's job properly there shouldn't really be anything to clean. If there is growth, it will come off without any aggressive scrubbing and they should never need to scrape.

We've used it for 8 years on multiple boats and never had a problem. The problems people encounter are two fold. First application issues from those not experienced with it. Second, other brands that are rip offs of PropSpeed.

We had a bottom job done on a 74' yacht at a yard in the Miami river. They were big on selling jobs while the yacht was out. They assumed we would want prop speed (didn't have it before), so they abraded all the metals with 40 grit discs. It looked like they combed it with a rake. We told them to get stuffed on the Prop Speed and the prep work charges, so be careful when having the prep done.

Prop speed, application technique is critical. But divers merely wipe the surface to clean. Rarely if ever do they need any tools to remove any growth if cleaned every couple of months.

I use it on my bow thruster props, struts and shafts, rudders and trim tab bottoms. Works well.

hate to break it to you guys but it's not the application that is the issue with propspeed, it's the product that fails

I'd say you have a 50/50 chance of it falling off after a few months or keeping it for 1,5 seasons, if you like taking gambles go for it

I'd say to check your prep. Ive been using it for years on running gear, rudders, bow thruster blades, and trim tab bottoms. No issue with it falling off.

Not sure what experience you have with prop speed or boating but we've been using it since 07. Professionally applied by Merritt's or Spencer never any issues.

Hate to break it to you, but you're so obvious with your one post. How long have you worked for a competing product?

Propspeed for 10 years on a total of 8 boats. All professionally applied. Never a problem. Just wipe gently every month when bottom cleaned. Works 100% as advertised.
