The engine location is fantastic for easy access and causes no issues with heat. If you are concerned about heat, you can always add extra insulation around the inside of the dog house. All of these boats came with a bilge blower that could be used to pull any excess heat out of the cabin while the engine is running if you find it is an issue and if the blower is still there. (Yes, diesel powered boats came with it too for some reason.) The engine location also provides for a huge storage space below the cockpit sole. My boat has the hot water tank and engine batt. located there along with additional storage space. Only problem with the engine location is walking around it while someone is in the galley trying to cook. Its a minor inconvenience.
Only real areas of concern would be to check the foredeck for any gelcoat cracks and/or delamination issues, particularly around the the forward edge of the coach roof and around the pulpit. The CB pivot pin can be an issue, but many - most of these boats have likely had it replaced already. Check to see if it has been done. If not it will likely need it in the not too distant future. Not a huge job, but a bit of a pain in the back side. inside CB controls are easy to fix if there are any issues. CB drooping below the trunk is a very common problem, but I have found it is easy to fix with some minor adjustments on the cable/winch. Lower rudder bearing is reported by some owners to need replacing, but I haven't had any issues with it. Check the rubber exhaust muffler that is located under the chart table. They are getting old and can fail allowing exhaust and cooling water to dump into the boat. Replacement mufflers are no longer available, but there are ways around it.
There are still quite a few parts available from Tartan if needed.
Other than that just look for the usual old boat issues mentioned above regarding the rig.
