The guy down the road from me is selling his boat, 1984 Champion bass boat with trailer and 150 mercury. He only wants 1000.00 for everything. He said the lower unit on the motor went bad and needs fixed. Everything else on the boat is in great shape including the trailer, trolling motor and 2 fish finders. Nothing mechnically wrong besides the motor. Would it still be worth it to purchase the boat even with the lower unit being bad?
