I pulled this off a US site,

"yep, a fresh water flush after any salt or high mineral water use, use of the correct anodes and keeping the anode surface clean.http://forums.iboats.com/clear.gif if the anode is not dissapearing odds are its either calcified or lost its electrical bond and is now just another piece of metal along for the ride.http://forums.iboats.com/clear.gif how often do you use sandpaper to clean the deposits from the anode before launching?http://forums.iboats.com/clear.gif once its got that white powdery coating its a usless piece of metal.http://forums.iboats.com/clear.gif 6 years in saltwater is an average life span for a saltwater cooled aluminium block/head assy.http://forums.iboats.com/clear.gif frequent flushing and anode maint will help some."

Should I be sanding my anode?

The surface between the anode and the outboard is the most important part. If the anode is looking stuffed then just replace it. Its cheaper than replacing the outboard.

BTW. There is a good chance that the stainless bolt will be the main conductor, so keep an eye out around that too. It the surface around the bolt is badly corroded, replace the anode.

Don't ever hit them with a wire wheel to clean them up.
If your going to do it (it isn't a bad idea) use the coursest bad ass file or sandpaper or just rub it on the concrete.
Some jointing paste between the anode and outboard isn't a bad idea either....but not grease or nickel or copper based never seize.

i have never heard of anything dumber in my life. As andy said just replace it if it looks like there isnt any more conection
You could also say that if your outboard isnt in the water all the time the anode wont work anyway my 2 cents

How do you know if there isn't a connection??
Do you look for the corrosion around the motor and if the anode looks good and the outboard is falling apart you replace the anode??

My way of thinking is to take it off so you can inspect the anode, mounting bolts/screws, mounting surface and do a clean and then reassemble.
That would usually take 5-10 minutes out of your life.
If the anode gets too small then replace as some are quite expensive.
That also makes sure the mounting bolts/screws do not become stuck...because they're a pain in the date when they get stuck.

Finga I don't understand about the jointing compound. Isn't the idea that you want the electrons to flow from the anode to the motor hence the anode is depleted. By putting jointing compound between the two you would be preventing the flow.

I assume Finga is referring to conductive jointing compound to ensure a better electrical bond.

Its not really an issue on a trailer boat. You could happily run without an anode.

6 yrs lifespan for an alloy block????? Give me a break..... Gee there are some rubbish talkers out there.

Wonder what he says about all the outboards out there that are older than 2003????
