Okay, that helps. You're gonna hear a lot of, "don't buy a boat with 20 years of issues" advice. I think you know the caveats, buying used so I'll spare you. Do the obvious stuff: compression check documented, inspection by your mechanic, and a lengthy on the water test where you test every single function while in the water. In the water is important. You're looking for any hull damage or rot, weird handling on plane, any mechanical issues with the motor, steering, or throttle, and any issues with the switch gear. Livewell/plumbing issues are usually not too hard to fix, but sometimes difficult to locate. Last thing check the trailer, bearings and lights. Lights are an easy replace, but it's a bargaining chip. I've had a few used boats, one that was almost 30 years old. Aside from crummy gel coat on the top cap, it ran like the Millenium Falcon. Good luck, and post in the Show My Ride thread if you pick it up.
