Need Year & Gas/OIL Mixture Mercury 7.5 HP

[TBALL]

Looking for the year on a 7.5 HP - serial # 4081882. Also, what is the gas/oil mixture? Looking to purchase. What would you advise as a price range on a great running motor? Is it air or water cooled? The seller doesn't have much info.

Thanks a lot.

Not worth much (couple of Ben Franklins??). Don't know how it is cooled.
