… 🧐 It looked like some sort of a rust fungus growing off the side of this keel nut.
I decided on replacing all of the boat’s keel nuts one at a time.
I started with the worst one and this is what was found caked under “a little rust” after I cleaned it up.
The keel bolt studs are in perfect condition and there is no visible corrosion or pitting on the bolts.
What do you think could have caused such a massive deterioration of stainless like this and why would it be isolated only to the boat’s keel bolt nuts?
Bonus points: what would you recommend torquing the replacement keel bolt nuts to on a salt water deep blue cruising yacht for open water and at a local dock marina with both power and sailing yachts?
