You can see just how long the genuine zinc type last in our local waters,while the anode on the left looks in bad shape,check out how little weight it lost in 24 months,its been working well but not fallen appart as you can see.
Twice as nice,zinc anodes in place.
An anode suitable for a propellor shaft.
Left click the above,it will open full size so you can easiliy read it.
Well its a choice you may have soon to make,some shops are starting to display the new alloy types,they say they are better and cheaper,I dont know about you but when my nice 18" Max Prop is concerned,price is not the issue,Rod and Mary off 'Sheer Tenacity',a new Shearwater 39 by Dix Design went the alloy anode route,four months later they were rubbished,so make you own choice.Thanks to Errol of Protea Foundry,Cape Town, for supplying the facts sheet when I spoke to him about the matter,I stocked up on a double issue of nice 35mm shaft sized Zinc anodes,I always fit two at the same time as well.
