After letting an engine set that long. I would at least remove the back plate and check the rear bearing if you can detect any redish coloring on the crankshaft, bearing or in the case, I would not run it. Then again with the back plate removed and it is nice and shinny
by all means go for it. You can also detect bad bearings by rotating the prop back and forth. if it feels smooth while rotating OK if it feels rough while rotating more than likely you will need to put in a new set of bearings
