I replaced all the Sea Dek on my 200 recently because it basically wore out after the previous owner scrubbed clean it a few too many times, and then the sun beating on it finished it off. If you do it right, it is a royal PITA to replace. Between having it peel up in pieces, going through several bottles of Goo Off and paint thinner to dissolve all the remaining adhesive, prepping the surface with rubbing alcohol, it was many hours of misery and cussing. I look at the Sea Dek nightmare on the new Nautique and all I can see is misery when it comes time to replace it.
Pump the brakes on the glut of Sea Dek and putting some upholstery in its place please...
