Any magic coating to keep critters off plastic props?

    Splurged on a new prop for my Vetus thruster: Plenty of growth in my brackish canal, both barnacles and slime.
    Used regular anti fouling paint before, with mixed results:

    Thruster and boat is being used at least once a week come hell or high water.
    (Neither so far :confused:)

    The new prop deserves some TLC, so I called Vetus and asked what they recommend?
    Nothing they said, but they are aware some folks use Barnacle Busters. (For cleaning maybe, don’t think it will be useful at all as coating.)

    What does the experts here at YachtForums use, if anything?
    (Let’s keep Covid-19, Trump and the usual stuff out of this:cool:)

    I used a good A/F on mine. Worked pretty well but I don't have the same warm water growth you have. I'm also curious to see what others are doing.

    Definitely a difference between Alaska and Ft. Lauderdale. I never saw so many barnacles in my life as when my boat lived there, and my boat moved every day.
    Given the speed of those props you'll need something real slick and hard.

    I've used Propspeed on metal thruster props, no idea if it would work on plastic, or even stick for that matter.

    I’ve heard hydroxychloroquine can really defeat those bugs.

    According to the bottompaintstore.com, Propspeed's "Clear Top Coat without the use of the etching primer can be used on plastic based items such as underwater lights, composite propellers and plastic bow thrusters." There is, also, this caveat: "Propspeed clear coat is a soft coating and is easily damaged by mechanical abrasion, fi shing tackle or ropes around the running gear. Vessels used in shallow, sandy areas are also prone to mechanical abrasion of the clear coat."

    They say similar to Prop Speed except DIY.

    I checked the website, no mention of plastic propellers, sent them a message asking about it.

    Yes, I use prop speed. Use it on the thruster props, running gear, rudders, underside of the trim tabs. Prepped well, it works well. Nothing is perfect.

    I'm sure many will benefit from hearing their reply.

    Used prop speed on metal props, rudder and trim tabs as well.
    Lasts about a year in Florida, looks like I will try it on the thruster prop this time.

    If you have or do your own bottom maintenance, you could try something like this,

    I have no experience with it, but a wax that can be reapplied under water makes sense for a surface that doesn't hold coatings well to begin with.

    From the manufacturer of Prop Glide:

    Not doing my own bottom maintenance, just doing an oil change and new prop on the bow thruster. Last time in (another) yard, they screwed up the bow thruster service, doing it myself now.

    Thx, that may be the future, but for the short term, as in the few days my tub is on the hard, I just need to smear or spray something on.
    Asked the Yard Boss today about using Prop Speed on plastic, without the primer, as suggested above:
    He said it was a bad idea, but he had something better and he would take care of it. (Prop Coat)
    So, I will try that, worst thing that can happen is that it rubs off over time and we are back to the bare plastic which is what Vetus recommended anyways.

    When the future comes try putting a bunch of pimples on it and see what happens. In fact maybe Vetus should try it.
