Just purchased a 1994 232 sports cabin. New to Parkers.Not too happy with the scuppers being underwater no doubt partially because of the twin 150 Mercurys hanging off the swim platform. Also I found two zincs on rhe bracket that holds the swim platform, when I removed the cap bolts water came shooting out. Is this 'bracket' a tank?.......Can someone suggest a gadget fot the scuppers to keep outside water outside?
