Good afternoon folks

I am new to this forum so hopefully this hasnt been asked before. I have currently taken ownership of what appears to be a Monark-Crescent 25HP outboard. The engine cover states 25 and the only other info on it says MCB.

Above is a picture of the manufactures plate on the engine itself. I would love to know any information if at all possible on this engine. I am hopefully going to get it running but as its not been running for years i feel knowing as much as i can before stripping and working on it would be beneficial.

Any help at all would be appreciated.
