I had a former Bennington Pontoon that was destroyed in an August storm in Northern Michigan a number of years ago. We were very satisfied with the boat so we replaced it with another Bennington 4 years ago and have been equally satisfied, except for the overheating problem with the 60 hp Mercury engine, but I had that fixed. Our Bimini top is of a much thinner canvas/material that our original boat and is not keeping water out of the interior of the boat when it rains. I waterproofed it again a month ago and it didn't help. Has anyone else experienced the same with their Bimini top and any suggestions besides paying about $1500 for a new top when the existing is 4 years old?
