Archimedes penta hp?

[Flyingdragon_uk]

Can anyone help me? i recently purchased a Archimedes Penta 50 outboard, it is a air cooled single cylinder with no clutch, and I dont know the hp, at a guess i'd say it could be around the 6-9hp size, its engine number is 091303262.<br /><br />Any ideas?<br /><br />Ta.
