FORMULA
Knowing the controls and indicators on your boat
is essential for safe and proper operation.
GAUGES
Your Formula boat is equipped with two sets of
gauges. The port set is for monitoring operation of
the port engine. The starboard set is for
monitoring operation of the starboard engine. The
gauges are illuminated for night operation.
On occasion, a small fluctuation in a gauge
reading is not unusual. If an instrument reading is
outside the normal or recommended ranges,
determine the cause or see your Formula dealer.
Refer to the propulsion unit operator’s manual for
normal recommended ranges.
Tachometer—Registers engine speed in
revolutions per minute (RPM). Use this gauge to
keep the engine within the proper operating
range.
An hour meter is incorporated in the tachometer.
The hour meter accumulates engine operating
time, and is activated when the ignition switch is
ON. Consult your propulsion unit operator’s
manual for the proper RPM operating range for
your engines.
Tachometer
Figure 4-1
Speedometer—Registers forward speed in miles
per hour. Use this gauge to monitor fuel
consumption and propeller performance. Since its
input is received from a water pressure hose,
accuracy is only approximate.
Fuel Level Gauge—
Measures approximate
level of fuel in a fuel tank.
The left gauge indicates
the fuel level in the port
fuel tank. The right gauge
indicates the fuel level in
the starboard fuel tank.
The ignition switch must
be in the RUN position
to activate the gauge.
Since the accuracy of your gauge varies with the
attitude of your Formula boat (trim and list), and
the fuel pick-up tube cannot withdraw all fuel out
of the tank, please observe the One Third Rule.
Use one third of your fuel to go out, one third to
come back and one third as a reserve.
