I am starting a restore of a 1985 Champion 19' Champ. while taking off the old transducer just to the right of the drain plug water came out when I removed the screws. there was no water in the bilge area and the area where the srews were is in the foam filled part that is sealed by fiberglass. Has onyone experienced this before? is the foam water logged? if so what is the fix, will it dry out does it need to be exposed, torn out and replaced? this is my first fiberglass restoration so any help is greatly appreciated.
