It is fantastic. Probably the only engine left of this model. Marna Diesel 1 cylinder. The boat was the "ambulance" boat used in the islands around Arendal Norway. The only one left also.
It is not working now unfortunately, but there will be a time when I will both spend time and money to get it fixed. Probably nothing less but USD 30-40K to make the real beauty, but it will be worth it.
