[C320-list] Prop shaft anode

[Daryl Hunt]

Hi all,

     I'm a fresh water, Great Lakes sailor with the '99 C320 #660 
"Believe."  Over the last few seasons I've noticed my prop shaft is 
covered with a rough brown mineral-like coating when I haul out at the 
end of season. It also coats the stainless steel components of my 
Kiwiprop. It's not organic and can only be removed by sanding.  My first 
thought was that it was electrolysis of the shaft, but the anode had 
clearly been doing its job and well pitted.  My theory is that the 
aluminum anode (recommended for fresh water) was depositing aluminum 
oxide on the shaft.  Has anyone of you other fresh water 320 owners 
experienced this?  The deposit cleans up fairly easily with #200 grit 
sandpaper.
