(see section 10-5).
Economy
The distance travelled per unit of fuel used. The value can depend on the type of speed sensor (see
section 10-5). The larger the value, the better the fuel economy. Adjust the throttle and trim to achieve
the best economy.
Fuel consumption curve
A graph of fuel consumption and boat speed as a function of engine RPM. Use the curve to monitor and
optimise boat performance (see section 10-6).
