Ok ,, New guy here , My name is Jamie and I live in Victoria ... New to the fiberglass boat thing , just got a steal of a deal on a 16 ft double eagle ... So I was cleaning her up ( shes been sitting a while ] and I find a brass plug in the rear of the boat that screws out it seems to go to the lower [ sealed ] portion of the hull . What is this for ? How do I check for H20?<br />Is the bottom oof a Eagle sealed ???? <br />Any help would be great <br /><br />thanks <br />the new guy
