The 1961 Johnson Sea Horse 18hp outboard motor typically requires a fuel mixture of 50:1, which means 2.5 ounces of 2-stroke oil per gallon of gasoline. It's important to use a high-quality 2-stroke oil designed for outboard motors to ensure proper lubrication and performance. Always refer to the owner's manual for specific recommendations and to verify the correct ratio for your engine model.
