If the keel is iron, you really need to coat it with some sort of protective coating, rather than just wirebrushing it and mounting it as it seems you're planning on doing. Usually, this involves priming the cast iron and then putting an epoxy coating over it of some sort. If you don't do this, and the cast iron starts to corrode, it will cause damage when it expands by 10% when it rusts.
You will need to bed it in some sort of sealant. 5200 could be used. I wouldn't use an epoxy in this situation, except possibly to fair the joint.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
