Got a 89 20 ft hydra sport the other day with a late 80's evinrude 200hp VRO. Firstly it cranked 2nd time ran strong, sounded good , visually inspected the motor saw no signs of wear and tear on the inside. Carbs will be cleaned, replacing fuel lines tomorrow. But my question is , what octane does this engine run off of? My buddies Johnson gt150 VRO v6 runs off 93. (Idk why I find that relevant) also what is fuel mixture. Will post a proper motor year and model later when I get the serial no.
