Fuel System Section 3
Fuel Gauge and Sending Unit
The fuel tank has a sending unit that sends fuel level
information to the electric fuel level gauge installed at
the helm station.
The fuel gauge powers up when the engine ignition
switch is turned to the ON position. The fuel gauge
displays the approximate fuel level in the fuel tank.
The correlation between the gauge reading and fuel
consumption is approximately linear from FULL to ¼
FULL. The accuracy of the reading decreases below
¼ FULL because of the tank’s profile.
The most accurate reading is obtained when the boat
is at rest and level.
! CAUTION
The fuel gauge reading is approximate. Verify
the gauge reading using other methods, includ-
ing the mechanical gauge on the fuel tank. Be
conservative when estimating fuel on-board.
