The ‘Power’ breaker switches provide power to each engine to allow them to run. When the
breaker is switched on, the low-oil pressure alarm will sound until the engine is started and the
oil pressure rises to normal operating level and the alarm will stop
The ‘Vent’ breaker switches turn on the engine room fans. Use these fans when you are
underway to blow fresh air into the engine room.

Bow Thruster
The Side-Power bow thruster joystick control is to the right of the engine
controls. To operate, press ON and ON simultaneously. Test the thruster
with a quick push of the joystick in both directions. The bow will be moved
in the same direction that you move the joystick; push
the joystick to the starboard and the bow will move to
the starboard. This thruster unit will turn off
automatically if not used for three minutes or, if over
used and electric thermal shut off switch will trip. If this
occurs, you will need to let the unit cool down. If the
thruster will not turn on, check the breaker in the

the louvered doors. The breaker switch is a big red
button which is a pull-on, push-off. Be sure the
button is pulled out.
The bow thruster circuit breaker is in the
forward stateroom in the cabinet under the
bunk. The normal ‘On’ position is pulled out.
