The Evinrude 235 hp outboard motor typically requires a fuel mixture of 50:1, which means 50 parts gasoline to 1 part two-stroke oil. It's important to use a high-quality two-stroke oil specifically formulated for outboard motors to ensure optimal performance and engine protection. Always refer to the owner's manual for specific recommendations and any updates regarding fuel mixtures.
