Shaft Through-hull Leak
I recently discovered that the prop shaft though-hull in my Pearson 28 was leaking. I initially though it was the Dry-Seal installed three years ago, but upon further investigation realized the leak was due to the sealant breaking down around the through hull (probably as a result of diesel spillage a couple of years back).
Hear's my question - does it make sense to apply 4200/5200 from inside the boat or do I have to replace the through-hull ASAP? I'd rather not haul out if possible, but only if it's safe (the water is seeping in pretty slowly at this point.)
Also: any opinions on using sealant vs. underwater epoxy such as WaterWeld?
