It ran very well but probably needs a tune up. It seemed the happiest at full throttle.
The biggest issue with it being too short was that it would occasionally loose traction as you speed up because there would not be enough water around the prop so it would rev higher but once I got it planing it was fine.
It looks very good under the hood (no rust). I changed spark plugs before we left and that's about it. I noticed that the adjustment pin on the transom mount is missing. Also need to replace the little plastic engagement trigger on the flywheel or it won't pull start. Where do you get parts for an old engine like this? Are they still available new? I'd be happy to sell it to you once I find a replacement.
