I am currently restoring a 23 foot, 4 berth Halcyon 23 sailboat in the Orkney Islands in Scotland. She has an inboard, petrol 2 cylinder Albin 0-21. Of course it is badged up as a Volvo c-10 but we know better. I have already found the AlbinMotor website for parts which is great and I am shortly to remove this engine for a service and maybe partial rebuild on the bench.
It was running in the last few years for the previous owner but the boat has lain idle for a while and I want to give it the once over before I start it and use it out at sea.
It is not raw water cooled but has a small heat exchanger which is fed by its own in-built electric pump which looks clever, I had not seen one like that before.
I don't have any specific questions about the motor yet but would be pleased to read any advice, comments or views on these inboard petrol engines. Should I refurbish or use it as ground tackle?

Best wishes, Mark in Orkney.
