    Does anyone have any knowledge of these Japanese medium speed engines? Any opinion if 23,000 hours (assume properly maintained) would be the end-life of the engine. No engine survey has been conducted yet, but just trying to get a handle on this. Thanks.

    No recent experience, but 23,000 hours are not much for this engine. You see them in Japanese fishing boats and other Asian commercial boats of the time. Also used in ships as generator power. There are probably hundreds running around the world. Parts are available. If you can rebuild it, it's good for a long time. Used parts including complete engines are available from ship dismantlers. I know some new parts are made in China.

    Thanks Lepke. My mate hasn't performed an engine survey yet, but I would assume that it was well-maintained since it was a government vessel all its life. I think only the last few years has been possibly "neglected" as privately owned.

    Over the years there's been a number of these engines come to the US in seized illegal fishing vessels. They seem to hold up well in that type of commercial use. Last time I worked on one, parts were easy to get. The dismantlers get not only the engines but all the spare parts they carry. I got new and used parts from this place in Turkey.
