My question involves a consumer law issue in the State of: Indiana

I purchased a boat that was advertised as an older boat, that ran good, needed minor mechanical work and needed to have the interior redone. Long story short - the engine blocked was cracked. The boat is junk. I disputed the charge through my credit card company and the the ruling was in my favor. I have contacted the seller and attempted to return the boat. He is refusing to accept the boat and informed me that he was suing me. This was over a month ago and I haven't heard anything from him. How can I resolve this issue?
