I just took my 1983 Mercury 80 hp Blue Band out yesterday on a 5 meter half cabin Australian Swift Craft. I kept it at approx 20 knots (backed off from full throttle which would be about 38 knots) for approx 80 minutes and used 27 Liters of Fuel. I was shocked that it used so much fuel.... was thinking sail boat. Or at least always cruising with the wind at my back. I noticed the huge difference in consumption coming back against the wind. It was my first time to measure fuel consumption. I'm still playing with cruising speeds.... Guess we are back to the sixties.
If not using oil injection, the 80 hp Mercury outboard requires a 50:1 ratio, roughly one pint of 2 cycle oil to six gallons of fuel.
A 4hp Mercury outboard requires a 50:1 fuel to 2 cycle oil mix.
The fuel consumption of a Mercury 200hp outboard engine typically ranges from about 10 to 16 gallons per hour, depending on factors such as load, speed, and operating conditions. At cruising speeds, many users report an average consumption of around 12 gallons per hour. It's important to consult the manufacturer's specifications and conduct real-world tests for more precise figures based on specific usage scenarios.
The 7.5 hp Mercury outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
The fuel consumption of a 1999 135 hp Mercury outboard typically ranges from 10 to 15 gallons per hour at wide-open throttle, depending on various factors such as load, operating conditions, and maintenance. At cruising speeds, the consumption may drop to about 6 to 10 gallons per hour. It's essential to refer to the owner's manual or consult with a professional for more precise figures based on specific usage conditions.
A 50hp Mercury outboard, requires a 50:1 fuel to 2 cycle oil ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
