Because there are so many factors which can affect your fuel consumption, the only true way of determining your individual fuel consumption for your particular boat is to perform your own fuel consumption "test".

Take one gallon of fuel and run your outboard at wide open throttle until you run out. The time it takes to use the entire gallon of fuel is your individual fuel consumption amount and would be considered the shortest time you could go without running out of gas.

Now do the same thing but vary the speeds from idle to wide open throttle. In other words, use the outboard like you normally would. You will now know the shortest time you can use your outboard before running out of gas and the average or normal time it will take you to run out of gas.

Nissan Outboard Fuel Consumption
We've put together the chart below to help you determine what type of fuel consumption you can expect from your Nissan outboard. Please remember though, all figures are approximate.

There are a great deal of factors that affect the amount of fuel consumption and therefore the figures listed below will not necessarily be what you will obtain. Factors such as weight, hull shape, hull condition, water conditions, etc. may drastically affect the consumption figures shown below.

The following chart shows the approximate fuel consumption of each model:
