Haul it
Mojito,You should haul the boat. Through hulls are drilled across the laminate and unless they are sealed with epoxy before your through hull fitting is installed (they rarely are on production boats) then you run the risk of water wicking into the laminate which can increase the likelihood of blisters.I know this isn't the answer you wanted to hear but if you look at it over the long run, a haulout & proper fix of the leak is the cheaper way to go.Just my 2 cents.Allen Schweitzers/v FalstaffC-30 Hull# 632
