Yanmar 2qm15 diesel marine engine, complete

I purchased this engine as a replacement for the one in a Spacesailer 27 that I owned, but my plans changed and I sold the yacht before fitting it.
Unfortunately, I don't know the engine hours, as there was no hour meter with it when I bought it.
I haven't run it since purchasing it, but the gentleman I bought it from had it running on the stand it's bolted to in the photos. It came as a complete engine with the gearbox, starter motor, alternator and engine mounts
