it with Zinc rich epoxy

Had this before... First I would take a maker and mark the bolt forward and aft. Next I would tackle, loosen one "nut" at a time and see if the stud or bolt move in the keel
. If the bolt moves... it means the nut and bolt is seized. This is caused by the stainless not being lubricated when it was assembled at factory. I would wait for a haul out
to tackle this.
If the bolts is stationary and the nut can be loosened... you are in luck! (DO ONLY ONE AT A TIME). Take the nut off and remove the washer. If you clean with a wire brush, make sure the wire is stainless and not steel
. I would clean this with sandpaper and check to see if the bolt has been sacrificed by rust. Vacuum the dust out. If the bolt is good... lubricate the nut with anti seize compound and reinstall and tighten very tight of with a torque wrench to make sure all bolts are tighten evenly. I would not paint
, or epoxy
. I would spray with Fluid Film or some other rust preventer.
After reinstallation I would mark (with a marker) the nut in relation to the bolt, just for reference until the next time you go down there and check. I my opinion, the rust shown is not much and easy enough to clean. I also hate rust with a passion...
