Outboard Motor Fuel Consumption

We've put together the chart below to help you determine what type of fuel consumption you can expect from your Tohatsu 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:
