Need some help. My 17 year old son is a new boater & has fallen in love with an older boat. It's a 1983 cheetah Bass boat but there are issues. He's saved up his money all winter to buy a boat. We are being told that it takes in about 3 gallons of water after being out for 4 hours. The boat owner has looked for holes & cracks but found none. He does not have time to figure it out & just wants to get rid of it. We are also told that the motor skips occasionally when running. We are going to go look at it tomorrow. What should be look for? Could it be the live wells? As a new boater, is he crazy to buy it? Any other advice would be appreciated.
