OK, it is not an aircraft engine, just an interesting observation. I bought this engine 15 years ago from a fellow that had it in his garage for 20 years with the cylinders full of oil. It is a flathead 4 cylinder sailboat engine with a design that dates to 1949. This is the early model that was built before 1969, how much before I have not researched the number. I opened it a couple months ago to check it out as a replacement for the tired engine in our boat. I was surprised at the condition and I would guess it only has a couple hundred hours on it. The rings were all stuck, but a slow fix. We put 11 hours on it last week on a 3 day trip, ( the wind never blows the right way for me), and it runs very strong.
