    Prop speed or equivalent questions

    New props arrived today. Thinking about what to coat them with. Wondering if any of you use prop speed. Noticed West Marine has a special on prop speed. What’s been your experience? What other products have you used?

    Have had very good luck with Petit's Prop Guard. Wrote about it last year -- photos are gone since the site transition but basically after a year, other than a light coating of slime, the props and shaft were clean without any barnacles or significant growth: https://www.baylinerownersclub.org/f...rd-gctid818878

      I've used Propspeed for many years now. Expensive but keeps the bugs and weeds away for two years minimum with a little rubbing on a regular basis.
      When bottom painting time comes, the props have to be sanded to remove any silicone left, same for the struts and rudders.

        In Puget Sound tried Prop Speed on rudders, shafts and struts. Did not keep barnacles off even 6 months.

          We have used Propspeed for the last 15yrs on our current boat and the previous one. Typically about 2 years good effective life from this product but alot depends on a sucessful application. We have had two major failures, neither of which where the fault of the product.
          First was due to an application carried out during winter and in rain - result - started falling off almost immediately.
          Second and most interesting for Woodsea was applying Propspeed to brand new propellers against the recommendations of our prop supplier. Apparently new bronze leeches oils from manufacture that will not let the primmer bond reliably. They were right and it came off soon after launching. The recommended preparation was to leave the new props uncoated for 6 months to a year and then coat them. This we did and never had a problem again.
