@ jkust,
The local SeaRay salesman (also the consignment place where I bought my boat) sent me this:
http://www.searay.com/boat_graphics/...DERNKAK512.pdf
It states that my SeaRay (in the same class as one listed) should weigh about 2600lbs.
Does that make you change your mind at all about the weight of 3600 for total weight including trailer?
A bit of research and I see that the Seville has a flat windshield, add-on swim platform for cuddys and cutout on bowriders, smaller powerplants (rarely the 260), a vertical stern, and was the entry level.
Sorrento has a curved windshield, integrated swim platform, at least a 260, stylized stern to integrate the swim platform, and was the uplevel boat.
I presume they know what they sold you and so it must be the Sorrento as the brochure indicates. If that is the case, your weights would be right about as expected....if it is the +-2000lb Seville then to me you have some extra weight in there somewhere. It is not at all uncommon for a boat of that vintage to have a rot issue. After enough owners, it only takes one bad one to improperly store it. I see waterlogged, old glass boats all year long as they are many times sitting way too low in water. Sometimes I can't believe they are still in service. Hopefully that isn't the case for you and nobody like to have to drill into their boat to test for rot but it is what it is.
