Press the power button in the lower left to activate the
AUTOPILOT p70R
. Notice
the rudder angle indicator. When compass heading is displayed the autopilot is
operational. Pushing
AUTO
will activate the autopilot. The boat will then maintain
the displayed heading. Turn the knob to adjust the course.
The Autopilot is calibrated for 40z operation at Boston Boat Works. If you notice
hunting rather than steady course-keeping, see the
Raymarine Manual to check
configuration parameters or contact Customer Service at Boston Boat Works.

TEERING
If a fault occurs which prevents one or both drives from being operated with the
steering wheel, it’s possible to align drive(s) to be aimed straightforward. If one
drive can be operated by the steering wheel, this emergency operation is
unnecessary.
However, if the non-working drive is locked in a disadvantageous angle, then
alignment will improve steering. The tools needed for this operation are delivered
with the boat with the commissioning package. (Refer to pages 77-79 in the
VPOM .) If steering is out of order at both drives, align both and use the
ENGINE/SHIFT CONTROL LEVERS
to steer the boat.

breaker on.
The primary purpose of the MULTI FUNCTION DISPLAY (MFD) is to show depth
in big numbers. The depth transducer is installed on the hull under the
companionway steps. Depending on loading, speed and wave action It’s about
2.0’ below the waterline and about 1.3 feet above the bottom of the props. (See
detailed design dimensions on page 43.)
The MFD may be calibrated to show the water depth from the boat’s waterline or
from the bottom of the propeller. However, we do not recalibrate depth settings
during sea trails and recommend keeping the 2.0 safety margin rather than
recalibrating. The bottom can come up fast and it’s helpful to buy seconds to
react.

The horn is a valuable tool that you

signals. See
