STEERING CONTROL SYSTEM
Lift Range – When the drive is tilted to maximum
height, but not when running, for trailing. Power trim
has an automatic stop that cuts power when the
preset end limit has been reached. The stop is
reset automatically when activating down
trimming. Never run the engine when the drive is
in “Lift Range”.
Auto Kick Up – Releases the drive if hits bottom
or an object in the water. This feature only protects
the drive when going forward. There’s no protection in
reverse. If the function has been tripped and drive
released, it must be trimmed back to the original
position using the control buttons.
Check after any contact that the dirve or propeller are not damaged, or if there are vibrations from the
drive. If this is the case, then the boat (if possible) can be run at slow speed to harbor to haul and
inspect. Or turn off the and raise the damaged drive and run on the good drive. Check the oil level in
the drive. If colored gray, water has entered. If this is the case or other damage exists, contact an
authorized Yanmar workshop. If only the propeller is damaged, it must be replaced then the boat run to
be sure there is no other damage.
4.5 BOW-THRUSTER (Optional)
Normally, with the joystick control, one does not need a bow thruster. If one elects not to install
the joystick control system, then the boat can be operated like a conventional twin screw
sterndrive. In which case the bpw thruster can be used to increase the maneuverability of the boat
at slow speeds in tight quarters around docks and slips.
Passengers on the foredeck are at risk if the bow thruster is engaged
without their prior knowledge.
Consult the user’s manual for specifics about your thruster. In general, thrusters are best used in
short bursts. Prolonged use may damage the motor, or at least trip the breaker. When not in a
situation where the thruster may be necessary, leave it turned OFF to avoid damage. Consider
the fact that your thruster gets DC power from the engine start battery, which is charged by the
engine’s alternator. If the engine is not running, has not warmed up for 7-8 minutes to the point
that the alternator is charging the start battery, or running at idle, the thruster can consume more
energy than the alternator can provide. It is possible to discharge the battery or burn out a
thruster motor by over-use of the thruster.
The thruster automatically turns OFF after 6 minutes with no use.
Turn on the thruster(s) by holding down the two left buttons (or turning the switch to ON with
some models) until the activation light appears. (You will hear the breaker click) If the light does
not appear, check to see that the large red knob for the bow-thruster circuit breaker (below
ignition panel) is pulled out.
When operating the thrusters, allow a second or two for the propeller to
come to complete stop before reversing direction to avoid damage to
either the prop or internal coupling sheer pins (Extras in holder on
motor housing under accessed through seat or berth forward hatch..
Thruster zincs should be checked periodically and replaced if
significantly worn.
