Dose anyone out there own a early JC Tritoon that takes on massive amounts of water from above ie. from rain or when underway only?
I've caulked the heck out of the under side were the toon meet the deck, totally sealing the top from the waves but it still just pours in. Early JC Tritoons had a unique tube design with a large flat area underneath you could hear buffeting in rough water.
Maybe a hairline crack?
