anodes and SS props

[DavidJ]

Just finished reading a recommendation on boatdiesel.com that if you have SS props then the galvanic action is more and you need to replace anodes every 6 months.
Anybody else experienced rapid anode erosion with SS?

There are various factors involved here, including the temp, and salinity of the water you are in, and the quality of your anodes, ( cheaps ones last forever!)
Also if you are in a marina and someone has shorepower with an earth problem it can affect your boat if you are between the other boat and an earth point like pilings or steelwork. The current can and will flow through your boat as opposed to around it, causing your anodes to corrode faster than normal. Regarding SS props, I have had a SS prop on my boat for 7 yrs now and my anodes easily last a whole year,and the boat is only lifted twice a year for cleaning. As you can see there are no hard and fast rules. I have a very good set of technical notes from a course I did with Mercruiser which explains this in great detail, if you want a copy send me your email address.

My aodes are rapidly going and I have been told to double up on the one underneath the transom. They never went this quick with Alu props.

I'll pass on the notes but I always appreaciate the technical quality of your replies.
thanks
