Seems solid,do you mean it isn't cored?Bruno made more solid glass 35 hulls than the 42.I know of a lot of Brunos that are cored and some are very wet,but they all are still being used.The biggest problem with them is resale,and a surveyor that doesn't like them.In some cases it may be hard to insure.The earlier hulls were put together better from what I have seen.As for a 3116,not the best cat ever made,but there are a lot of them out there.Not a high hour engine in my opinion.
