Sacraficial Anodes not deteriorating

[ronjon444]

I have a 1981 SeaRay - Merc 260.

I have noticed the outdrive & housing have started getting white corrosion on the edges and corners. My sacraficial anodes look like new and are not deteriorating. Do I have a grounding problem? The boat operates fine.

Any recomendations appreciated.

Re: Sacraficial Anodes not deteriorating

take them off, clean them with a green scotchbrite pad, clean the area they bolt to, then re-install. usually they loose their grounding bond and they become coated with minerals in fresh water.
