I had a guy call me wanting to trade his '83, 16' Charger Bass boat for my Tritronics 2 dog shock collar setup. The boat sports an 84 90hp Yamaha outboard. The boat and motor were last tagged in '02. He said the motor is seized. I went and looked at the rig last night. Exterior of boat looks good, transom seemed solid, trailer in good shape, interior needs some attention. I noticed that the boat has a built in fuel tank. I pulled the cap and didn't like what I saw. I am wondering if there is a method of being able to clean one of these tanks properly? He had the rig listed for $800 on Craigslist, but after looking at it, I think it's worth a lot less. I have the collar setup listed at $325. I know it's worth that much or more. I guess I'm really asking if you guys think I could make a buck or two from doing the deal. I'm thinking about checking into the motor and find out what's up with it. If it can't be repaired reasonably, then perhaps parting the thing out. The boat and trailer might bring about 5 bills if cleaned up. Your thoughts?
