I believe this is a very old Yanmar raw water cooled diesel engine with transmission or something very similar. This is for parts or maybe restoration. The majority of the parts are there including an extended hand crank tool. Turns freely with no binding. There are no data plates or numbers I could find. It was a training motor for a trade school and was headed for the junk pile. I grabbed it thinking I would have the time to get it running again but life has gotten in the way.
Local pick up only.
