Re: Grease on Propeller for Anti Fouling?

I think he is reffering to the color of the strut...some sort of coating?

in any case...guys dont polish your props...really....

do you own an ofrshore racing catamaran with 1500hp worth of outboards? abdsolutely no gain doing that


in effect polsihing a prop melts the top layer of most materials

when people say machine polished or buffed down here especially on magesium, aluminum and some forms of stainless what happens is the top layer gets soo hot that it melts...this closes it all up which is good for stuff like chainplates

mirror polished is what they call it

indeed a rough porous blade is the perfect PRIMER for a simple sprayed on antifouling or nothing at all

again if you have a boat with an inboard and power cruise a lot you will notice less growth than when you only use your inboard to enter ports...

on all the boats I have had with inboards I never did anything to the prop...yes the strut or a arm etc but never the shaft or prop

why? cause you can unbalance a prop quite severely by globbing on antifouling....

youd be surprised how much vibration can come with heavy paint not just barnacles....jejeje

cheers

I believe you're correct - to be honest, I can't recall, for certain...

I had definitely coated the strut with West epoxy and copper additive as a primer... but I think I had sprayed it with Barnacle Barrier, having also done so to the wire I ran between my keel and rudder...

In any event, I was definitely underwhelmed by the performance of Barnacle Barrier in my home waters :-)

I got some of this:
LanoCote Prop & Bottom

Have not gotten a chance to put it on. I got a bad barnacle problem- in 3 weeks prop, strut and shaft are covered.
