Windlass Corrosion - Moody 36

[Dann]

After 3 years the SL Horizon electric windlass on my Moody 36 c1997, suffered severe corrosion to the casing. The casing was replaced under warrenty by Lewmar (who took over SL), who suggested the cause was inadequate insualtion between the alloy windlass casing and the stainless steel plate it was mounted on. They also supplied an insulating pad and a special paste to insulate the stainless bolts. 4 years later the casing is again showing signs of severe corrosion. I should add that the windlass is situated in the bow locker where it get regular doses of salt water, but is well flushed with fresh water and dried whenever possible. Has anyone else experienced this problem and come up with any long lasting solution?

Could there be a very slight electrical leak? This could cause this problem, even if the salt water was getting at a connection inside? Just a thought.

Might your locker be filling up with water?
If your chain/warp/bits of corroded windlass are blocking the locker drain hole then the locker might fill with water as waves break and not exit quickly enough.
Yes, it does happen................sob,whimper.

Many thanks for your suggestions ccscott49 & bugs. The windlass is isolated by a cct breaker on +ve side unless in use, so doubt that there are any electrical leaks. Also the locker is well drained. I was hoping that other Moody owners with similar arrangements would be able to say whether they had experienced anything similar. It appears not. I will try liberal amounts of Hammerite and see what happens !

Not familiar with your windlass, but I had a similar problem of a mixture of metals on my sillette drive leg. Never did totally bottom it, but very careful painting and the use of duralac on every stainless fastener did keep it under control.

There are so many possible electric paths (down the chain for example) that you will not win completely.
