The recommended fuel mixture for a Mariner 15 hp 2-stroke outboard engine is 50:1, which means 50 parts gasoline to 1 part 2-stroke oil. This ratio ensures proper lubrication and performance of the engine.
How to Mix the Fuel
- Use Unleaded Gasoline: Ensure the gasoline has a minimum octane rating of 91.
- Use Certified 2-Stroke Oil: Use oil that meets the TC-W3 certification, such as Quicksilver Premium 2-Cycle TC-W3 Outboard Oil.
Mixing Process:
- Measure the gasoline and oil accurately.
- Pour the gasoline into a clean fuel container.
- Add the 2-stroke oil to the gasoline.
- Mix thoroughly by shaking the container.
Example Calculation: For 1 gallon (3.785 liters) of gasoline:
- Gasoline: 1 gallon
- Oil: 2.56 ounces (approximately 75.7 milliliters)
Important Tips:
- Avoid Ethanol-Blended Fuels: Fuels with more than 10% ethanol are not recommended as they can cause engine damage.
- Proper Storage: Store the mixed fuel in a clean, sealed container and use it within 30 days to ensure freshness.
Following these guidelines will help maintain the performance and longevity of your Mariner 15 hp outboard engine. Regular maintenance and using the correct fuel mixture are crucial for keeping your engine running smoothly.
