I came across two old Mercury outboard 25hp motors hoping both work or can make one work out of the two. Came from an estate sale therefore no owners manual or registration.
Never had a Mercury outboard before. I have determined they are 1994 models. Does anyone know the gas/oil ratio or a website that list such information.
Best guess I can find for this motor is 50:1 or 8oz/6 gallons.
you would be better served to look on ebay and find a mercury manual specifically for your motor
the aftermarket manuals are okay, but the merc manuals are much better
