FIXING KNOB
To hold the throttle at a steady setting,
turn the throttle fixing knob
clockwise. To free the throttle grip
for manual speed control, turn the
fixing knob counterclockwise.
OPERATION (H type)
When cruising at full throttle, note
that the engine speed must be in
the range between 5,000 min
(rpm) and 6,000 min (rpm).
If you feel that the engine speed
jumped up when the hull jumped
or at ventilation, cruise the boat by
returning the throttle to the slow
speed side.
''
See Propeller Selection (page
45 ) for a relation between the
propeller and the engine speed.
Do not operate without the
engine cover. Exposed moving
parts could cause injury; water
may damage the engine.
For best performance, passengers and
equipment should be distributed
evenly to balance the boat.
