In addition my thought has always been that the continued rotting of the core material (for those materials which will rot
- balsa, plywood
, etc) that the materials structural integrity is slowly decaying. I also worry that the stainless bolts going through a wet deck
with no oxygen is a great place for crevice corrosion
, so sealing in moisture and sealing out oxygen might not be the best practice.
Having had to eventually replace significant portions of deck core on various vessels where the wet core had been sealed up and allowed to continue to rot
I have never been comfortable with that approach.
It probably depends on if the vessel/owner is a "use it up and throw it away at some point in time" or "owning a vessel for the long haul". I owned my previous vessel for 19 years and I expect to own the current
vessel for at least that long and so the "value" to me of doing what makes me feel I have done a good job as a steward of the vessel gives me pleasure.
If the core is rotten, it needs to be replaced.
If the core is just wet, maybe not.
No worries about stainless, the bedding compound will isolate it from the wet core.
Better yet to over drill, dry, and resin pot the mounting holes.
But I have no concerns about rebedding fittings in a wet core that isn't rotten. If there is no rot to begin with, and then the leak is sealed, rot can't start, it needs oxygen.
I have inspected/rebedded lots of wet cores with no rot that don't smell bad.
I highly doubt your musty smell is coming from sealed wet core. More likely standing water
or saturated wood or fabric
inside the boat.
