I am in the process of purchasing a lakefront home. The sale of the homes includes a boat called a Supra Beast. I was told it was built around 1988-1989. The current owner said it has a 500 CC Chevy engine. I do not know much about boats but want to learn a few things about it. Does anyone have any infomation or a genral value to this boat. It appears to be in good shape and is a 20' in length.

Thank you
