Well it is 38 yrs old, so depending on how well it was Maintained. it might be good, or it might not be.
Boats that old often have problems with any Wood in the Boat(floors, Transom), the engine, Do a Compression Test, Check that it has a Spark that can jump a 3/8" gap. Put a set of muffs on it and see it will start. If you buy it, first thing you need to do, is drop the Gearcase, replace, at Minimum, the Water Pump Impeller.
How it has been maintained is everything!! How it runs and how good the compression is will tell the story. Check the lower unit/ pull off the prop and check for leaks. Look over the wiring and see if dried out and cracked. Probably some plywood in the transom, if you can reach/ see it look for signs of rot. Not a bad job to replace on an aluminum boat... Last summer, I bought a 1992 Sylvan with a 92 Merc 40, all in near mint condition. Spent its entire life in a garage unless on the water. There are some very nice older boats out there, but you need to hunt hard and look close!!
