Warning Stickers
Speedometer
The speedometer indicates the water speed of the boat in
miles per hour. It is recommended that the speedometer be
checked for accuracy after each 100 engine hours.
Speed may be checked using a stopwatch and a standard
slalom course. Adjust the speedometer needle by turning
the knob at the bottom of the gauge.
NOTE: If the speedometer registers erratically, check
speedometer pickups.
Tachometer
The tachometer registers the operating speed of the motor’s
shaft output and may be used as an alternative to speedometer
if weight and water conditions permit.
DO NOT exceed the recommended RPM during break-in and
normal operation of your motor. Exceeding the manufacturer’s
suggested RPM may cause damage to the engine.
Speedometer Pickups
The speedometer pickup is located on the bottom of the hull. The pickup measures the speed
of water passing the paddlewheel. Poor water conditions or foreign material may clog the
pickup causing the speedometer to register incorrectly.
Inspect the paddlewheel and remove any foreign material only when engine is off.
Please see paddlewheel owner manual in the Boat Owner’s Packet
for more information.
ENGINE HOURS are shown on the face of the tachometer.
The engine hour gauge acts as an odometer for the engine.
Engine hours should always be noted and documented so that
required maintenance and lubricant changes may be performed
at the proper intervals.
