The fit also depends upon which 246 Islander you have. I have two Islanders but slightly different body styles. I did buy a set and it would fit one of my Islanders but I already have a metal set for it. They wouldn't work on the other Islander since the front sticks out a bit further. It is the one with the mounting screws near the bottom. I could tell that the body style had changed slightly but didn't think it would affect how the bottom covers are shaped and would attach. The back piece does fit fine but not the front. They did give me a full refund though I paid for the shipping. Cheers, Don.
