For most Yamaha 2HP outboard motors, the recommended fuel-to-oil mixture is typically 50:1. This means for every 50 parts of gasoline, you should mix 1 part of 2-stroke oil.
Here’s how you can mix the fuel properly:
Steps to Mix Fuel for a Yamaha 2HP Outboard:
- Gasoline: Use clean, unleaded gasoline with an octane rating of at least 87 (regular).
- Oil: Use high-quality 2-stroke engine oil, preferably one that’s designed for outboard motors. The oil should be specifically formulated for 2-stroke engines to ensure proper lubrication and performance.
- Mixing ratio: For a 50:1 ratio:
- For 1 gallon (3.8 liters) of gasoline, you will need 2.6 ounces (about 75 mL) of 2-stroke oil.
- For 5 gallons (18.9 liters) of gasoline, you will need 13 ounces (about 385 mL) of 2-stroke oil.
Important Notes:
- Always double-check your owner’s manual for your specific model of Yamaha 2HP outboard, as there could be slight variations in the recommended oil-to-gas ratio.
- Use a fuel mixing container to ensure you get an accurate ratio. A proper measuring container or mixing bottle often has markings for different oil-to-gas ratios.
- It’s important to shake the mixture well before each use to ensure the oil and gas are fully combined.
This fuel mix helps keep the engine lubricated while preventing damage from running it without sufficient oil. Let me know if you need more details or have any other questions!
