Howdy. I have an old Johnson outboard motor and we can't quite remember the oil to gas mixture ratio for it. I don't know the model number, (it's up at our cabin, while we're here at home, preparing to leave), I only know that it is a Johnson motor, with 9.9 Horsepower from the '70s, and it looks identical to the attached picture that I found on the internet, which labelled it as a 1976 Johnson Seahorse 9.9hp, or something along those lines. Relevant answers within the next 24 hours are greatly appreciated. Thanks.
