Prospeed a brand new Gori?


Recommended Posts

My Sail drive is coated in prospeed that is still in good nick. 

Fitting a new Gori folder in the next couple of weeks and have been told by more than one passer by that I should run it without anything on it for a season or so before sanding/applying any protective coating to it. I'm an inboard newbie so green as they come in this field... is there science behind this approach or should I take the sail drive back to bare metal and apply the Propspeed system to the whole lot?

Seems sacrilege to sand the new prop 🤣

While I'm on it, exactly how far out from the sail drive should you apply non copper based AF?

 

Thanks

I didn't put any on mine for 6 months, it was easy to clean off barnacles and then Propspeed, but the painter reckoned it didn't matter and he could paint it from new without any problems

Dont sand your Gori, as someone who has sold more Gori props here than anyone  -you can do as Ballystick says or just wipe with the solvent and Propspeed from new either way works. -hope you got a good deal on the Gori.

Gori or not, I have seen a bunch of people claim that they shouldn't coat their new bronze props for x months when new. There's no science behind this; we choose the variations of bronze for our propellers because of how close to inert bronze alloys are in a corrosive environment. When coated with propspeed or other silicone products it will have the best chance of staying in it's zen-like state without material loss. While yes, an uncoated prop will have migration of some alloy components to the outside, this isn't beneficial in yellow metal.

The cheap boat costs are adding up.

Why the Gori over say a 3 bladed Volvo prop?

Ex owner of boat purchased a new Gori to replace the one lost between me viewing the boat and paying for it.

Awesome, thanks guys. I couldn't see the reasoning in marring a near perfect surface to try and make it more slippery. 

Past 4 boats all I've had to do is tilt the outboard and corrosion-be-gone!

Follow what the paint system says. My tin of Ultra 2 says no closer than 30cm to any part of the drive.

I’ve always gone a bit wider to avoid possibility of interaction with a 50cm x 50cm square around the saildrive leg.
