Hi I have been reading about sacrificial anodes. It seems that it is recommended that any boat moored in any type of water, Fresh, brackish or salt, should have a sacrificial anode to prevent corrosion. My question is where and how many should I install?

I've never seen them used except in salt water. Put one on the prop shaft if it will make you feel better.

Unless your in salt water for extended periods of time and in a marina that has lots of ac current power cables running along the docks- you don,t need them.

We moor our boat all summer and the only corrosion I've ever seen is on alloy parts like the Malibu wedge and wedge plate. They corrode in fresh water. I've heard magnesium annodes are what works in fresh water, but have never seen them for sale, except as part of a freshwater annode package for stern drives and they were pricey.

I used to fly seaplanes in the Caribbean which was a loosing battle with corrosion. We had anodes all over everything and I think the key here is they "slow", not prevent the corrosion. In fact, one of our anodes fell off one of our floats and by the time someone noticed it, the metal it was mounted to had gone bad. We checked it vs the good float and there was not much difference.
Our best success was coating the insides of metal structures with a rubbery adhesive. This combined with a team of mechanics working all night, every night, sanding and priming metal. Long story short..........I wouldn't bother. Chris |
