Seakindly, good advise from macojoe. If I found a '94 for a good price, I'd be all over it. Yamaha went to the stainless shift rod that macojoe spoke of after '92. I would still have the motor checked out carefully, but that should be one less thing to worry about.
As for the boat itself, I wouldn't be concerned on whether it has wooden stringers or transom or not. The whole business about no wood in boats is great for companies that don't make a well constructed boat. There are many people, myself included, that prefer a boat with some weight to it. They handle the rough stuff a lot better than the lighter boats. The wood in the stringers could eventually rot away, but it's the fiberglass that encases the wood that gives the actual strength. A '94 should not have any transom rot problems for many, many years barring any catastrophic structural damage. I like the setback they made with the newer transoms. Should give you a lot more room in the cockpit.
You might want to consider finding a reputable marine surveyer to go through the whole boat for you. It'd probably run you a couple hundred $, but if it's a good deal to begin with, it may be money well spent for your peace of mind.
