I removed my seacocks and thru-hulls from hull #27 and the laminate/ coring is dry . Someone has filled the coring appropriately in the past. My question is should I replace the seacocks and thru-hull fittings if they are 25 years old? The ball valve has some minor pitting on the ball part of the valve but they are definitely working . I realize Marelon is much lighter but is it made to last another 25 years? My thru hulls are flush type which I like-- even though they have been criticized in the past.
