Probably ok to start it to verify she goes into both forward and reverse but I would also drain a little gear lube to look for signs of water in the lube which is a sign of bad seals.
The boat itself is no different than any other. Use a dead blow hammer to look for soft spots in the transom and stringers.
Let us know if you buy her and post some pictures.
