Boat looks to be in good shape. As noted the issue is parts availability and the difficulty in converting it over to a modern drivetrain (Old style Volvo, large transom cut out, won't take a modern drive system without fiberglass work). Check it all over for rot, if you find rot forget it. Really!
PS I think I see silicone around the transom mount, that means only a few things, leaks, rotted transom, etc. Proceed with caution, lest you wind up in the restoration forum asking questions.
