Rusty Keel Bolt

[thevdeub]

Hey,
My Keel Bolts are very rusty, but according to the "expert" it is not dangereous if under control.
see pictures.
i was thinking about
- cleaning with a metal brush
- rust eater & converter (phosporic acid)
- couple of coats of rustlok steel primer (urethane paint)

i am trying to dry my bilge, but would like to add some kind of coating / protection layer to avoid humidity but not create corrosion. kind of Foam or plastic, ...

any opinion on my situation ? would be really appreciated ...

i would seal it with butyl rubber after painting the same type they place in joints between teak deck boards or using hot tar and pour over the bolt head

What boat is this on? Type and material of keel?

Why a**holes put steel keel bolts on boats is beyond reasoning.

Sometimes it's best to leave well enough alone. Just dry it out and keep it that way.

Drop keel. Fix problem.

Here is why:
This;


is how this bolt appeared (the one to the right)
before the keel on my boat was dropped.

In all, 5 of the 8 bolts holding the keel on were toast.

The photos of your bolt look worse.

Thank you all for your answers. i found my dream thread in another category.
this forum is awesome, but there is so much content that it is hard to find very specific information

The boat is a Beneteau Oceanis 430 from 93', and i believe this is a Iron Keel & Bolts.
