Section 2 Boat Operation
Hour Meter
The hour meter records cumulative hours of engine
operation. The hour meter powers up when the
engine ignition switch is turned to the ON position.
Always turn the engine ignition switch to the OFF posi-
tion when the engine is secured from service. The
hour meter will continue to count time when the engine
is not running if the ignition switch is left in the ACC or
ON position.
The engine operating hours can be used to schedule
periodic maintenance for the boat and the engines.
Fuel Gauge
The fuel gauge powers up when the starboard 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
load is approximately linear from FULL to ¼ FULL .
The accuracy of the fuel level 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. Be
conservative when estimating fuel on-board.
