I've scoured our gallery/data sheets and don't anything specific about which outdrive they came with.
Do you have the 140 Merc engine? Maybe you can reach out to them (Mercury) and send pics on the engine and the outdrive - I'm sure they can ID it or tell you where to look for numbers.
What do you think? When you get the answer from them can you come back here and update your thread for others that have the same question, please?
