What is the mix ratio for an Evinrude outboard motor?

50:1
50:1 – Mix 100ml of oil per 5ltrs of fuel.

Recommended by Mercury, Mariner, Tohatsu, Johnson and Evinrude this is my preferred ratio for all outboards including Yamaha and Suzuki. You can confidently use this ratio for any horse power and just about all year models.

What is the oil ratio for a 2-Stroke Johnson outboard?

50:1
For 2-Stroke outboards that require a 50:1 premix of oil/gas we’ve put together the following chart to simplify the calculations. Use ONLY 2-stroke outboard motor oil with an NMMA (National Marine Manufacturer’s Assoc.) certified rating of TCW3. Never use automobile motor oil in your 2-stroke outboard!

How do you mix a 50 to 1 gas ratio?

You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you’re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. I would recommend using fresh gasoline that has an octane rating of 89.

How do you mix Evinrude Johnson 2 stroke oil?

How do you mix fuel for a 2-stroke outboard?

Use a 32:1 gasoline to oil ratio. One gallon of gasoline combined with 4 oz of two-cycle engine oil. If you are in the state of California, use a 2-cycle oil mix ratio of 40:1.

Should I use premium gas in my 2-stroke outboard?

Premium fuel is not only better for your equipment—it’s better for the environment, too. High-octane gas and high-quality, synthetic oil are odor-free and burn cleanly, so you can operate your two-stroke equipment worry-free.

How much oil do I mix with gas for outboard motor?

Converting to the U.S. System

How do you calculate the gas to oil mixture for a two-stroke boat motor in the United States? For a 50:1 ratio each gallon of gas requires 2.6 oz of two-stroke engine oil. For a 40:1 ratio each 1 gallon (gal) of gas requires 3.2 ounces (oz) of oil.

What happens if you mix too much oil in a 2-Stroke outboard?

Using the proper oil-to-gas ratio is important, but if you’re off, it’s better to mix too much oil into your engine than mixing too little oil. Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power.

What is the best fuel for a 2 stroke outboard?

91 octane unleaded is the best for most domestic outboards and garden tools. The outboards have low compression ratios so they can be used safely in third world country fuels, eg one outboard suits all the world markets.

What is the best gas for 2 stroke outboards?

87-octane gasoline
That said, your choice of fuel remains critical. Burning 87-octane gasoline in a two-stroke outboard causes carbon buildup that shortens engine life. Dose the fuel with a carbon-cleaning additive or fill the tank with 89-octane or higher fuel.

Can I put 91 octane in my boat?

Personal Boats

You can fuel it up similarly to your car! Personal boats can use the same type of gasoline as your vehicle, including unleaded (87 octane), mid-grade (octane 89), premium (octane 93), and diesel.

Should I run premium gas in my outboard?

Current recommendations are to use a minimum of 87 octane, 89 octane is preferred. There is no additional benefit from using higher-octane fuels, in fact they may cause hard starting conditions in hot weather.

What gas should I use in my outboard motor?

What Type of Gas Should I Use in My Boat? All current outboard, sterndrive and inboard gasoline engines are designed to operate safely on fuel with no more than 10 percent ethanol (known as E10), and under no circumstance should fuel with more than 10 percent ethanol (such as E15 or E85) be used in a marine engine.

Can I run premium gas in my outboard motor?

Putting lower-octane gas in a high-performance motor rated for premium gasoline may cause that motor to knock. Obviously, you don’t want that. But putting high-octane gas in a regular outboard won’t do a thing except lighten your wallet. It will not give you any more power.

Can you use 93 octane in a 2 stroke?

Any fuel type between 87-octane and the 92-octane will work just fine depending on the type of motocross bike you own. If you own a 4 stroke, for example, the 82-octane works just fine, but for a 2-stroke, you should go for the ethanol-free higher octanes (92 and 93) because the lower octanes tend to detonate.

What kind of gas does Evinrude ETEC take?

All Evinrude engines are two-strokes and have an onboard two-stroke oil tank that has a capacity of 3 gallons. They run on 87-octane fuel. Evinrude sells the motors with a five-year warranty on the engine and against corrosion.

What octane is marine fuel?

We now carry 93 octane “no ethanol” marine gas at the card lock service facility. No Ethanol Fuel for BoatsAbout Marine Gas – At Eli Roberts and Sons we are thankful to offer conventional (87 Oct) unleaded gasoline, commonly referred to as marine gas.

What octane gas is best for 2-cycle engines?

A minimum of 87 octane/87 AKI (91 RON); If operating at high altitude, see below. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable.

Is higher octane better for 2 stroke?

High performance 2 cycle engines love the octane they were designed for. Any higher octane rating over that will contribute to overheating and lower power. Higher octane fuel does one thing. It burns slower.

What kind of gas do you use for 2 cycles?

Two-stroke engines require one of two types of fuel: either a gas/oil mixture of 40:1 or 50:1. Always check your owner’s manual for your specific model before mixing the fuel. Finally, add the appropriate amount of 2-cycle oil (usually two 2.6-ounce bottles) to your two-gallon gan can.

Is TruFuel better than gas?

TruFuel is made specifically for higher-revving, hotter-running 2-cycle engines. Pump gas is made for your car but can wreak havoc on a small engine. Pump gas and oil can leave carbon deposits and gunk in your engine and fuel line. TruFuel is cleaner, enhances equipment performance, and is better for your engine.

Is gas with no ethanol better?

While not as popular as the ethanol blends, pure gas may be preferable for older car engines, as well as boats, lawn mowers or other tools. Ethanol-free gas also gets better fuel economy. However, most drivers use the E10 or E15 blends, with 10-15% ethanol. That ethanol content only reduces gas mileage by around 5%.
