How much fuel does a boat use per hour?

How much gas do boats use? Many small, personal watercraft boats tend to use 3-8 gallons of gas per hour at cruising speeds, while faster boats like speed and motorboats can use 20-30 gallons an hour. Depending on the weight, size, and style of your boat, you will use within this very large range.

How much gas does a outboard motor use redneck rule of thumb.

Why is my outboard using so much fuel?

The main reason why boats will always burn more gas than cars is they run on water. Aerodynamics, wind resistance, waves, and drag affect the fuel consumption of a boat. Basically, a boat needs to use more fuel to cover the same distance a car will cover.

Why should a boat gas tank never be full?

It's important to never fill the tank of your boat beyond 90% full. This leaves room for gas to expand and avoids the potential for overflow. Ensure that all air vents and valves to the gas tank are open.

There are good reasons behind those 9.9 HP motors: Some inland bodies of water have motor restrictions “under 10HP” only. Some states will require boat registration on boats with larger than 10 HP outboard motors.

What is a 9.9 boat motor?

9BTHS4 is a 15-inch short shaft with electric start, power tilt and electronic fuel injection. The Suzuki 9.9 HP outboard engine is lightweight, compact and fuel efficient at 120 lbs, and is desi…

What is the average mpg for a boat?

1. Average boat MPG. The first thing to do when you want to determine the fuel efficiency is to check the average boat MPG (miles per gallon). An average boat will need 1 to 4 gallons per mile at a speed of 20 knots, but many other factors impact gas consumption.

How heavy is a 9.9 hp outboard?

The four-strokes undeniable qualities carry with them a considerable weight penalty. For instance, the two 9.9-horsepower outboards we evaluated in this test exceed 90 pounds. One is just shy of 100 pounds. (Engine manufacturers actually label the 9.9 models as “portable.”)

Is Yamaha 9.9 fuel injected?

Answer: Yes it does. Yamaha 9.9 HP comes with a Precision Multi-Point Electronic Fuel Injection on the T60 and T50. It delivers the exact amount of fuel required for optimum efficiency and performance.

15HP engines burn roughly 1.5gph at WOT. 2 persons onboard and 12 gal of fuel+lots of other stuff for fishing etc. A 2 strokes engine consumes slightly over 12% at max stated rpm for that engine at wot, + 1.8 gal per hour. Ideal cruising once on plane 1/2 to 3/4 throttle.

Should you run an outboard at WOT?

Because propeller pitch plays such a significant role in the performance of an outboard or sterndrive, it's necessary to run a Wide Open Throttle (WOT) test every time you fit a new propeller. Whenever you purchase a new outboard or boat, it's wise to perform a WOT RPM test.

How much fuel does a 20hp outboard use?

Fuel Consumption at W.O.T: 6.2 L/Hr.

How often should I change my outboard oil?

Most manufacturers recommend you change your boat's oil every 50 to 100 hours of operation. Sometimes this is translated to once every year, whichever comes first.

Should I put Stabil in my boat?

Fuel stabilizer slows the rate ethanol absorbs water and reduces the possibility of phase separation occurring in your boat's fuel tank. This is why you should add fuel stabilizer every time you refuel your boat.
