Turn the throttle grip in the FAST
direction to increase the speed.
For the sake of fuel economy,
open the throttle about 80%.
When cruising at full throttle, note
that the engine speed must be in
the range BF75D: between 5,000
min (rpm) and 6,000 min (rpm),
BF90D: between 5,300 min
(rpm) and 6,300 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.
For best performance, passengers and
equipment should be distributed
evenly to balance the boat.
See Propelle r Selec tion (page
) for a relation between the
propeller and the engine speed.
To hold the throttle at a steady setting,
turn the throttle friction adjuster
clockwise. To free the throttle grip
for manual speed control, turn the
friction adjuster counterclockwis e.
