Have a neighbor with a 1968 Mandela 18ft. ski boat. He is original owner. Engine is a 389Pontiac (that sound right?) with three two barrel carburetors. Boat in Orange Co.,Ca./needs restoration/ don't know type of drive (haven't seen it). Is there any interest in these boats? This was strickly a ski application. I don't know a thing about V-drives, just doing a favor for him to locate any potential customers.
