TEERING
The engine ignition switches must be on for this system to function. The power assist
hydraulic pump is activated simply by turning the steering wheel. The hydraulic pump senses the
motion of the hydraulic fluid from the helm and pumps fluid in the cylinders at the engine
accordingly. The power assist pump is installed in the starboard aft berth rigging compartment
and can be accessed via the access panel in the aft berth wall. The power source for this pump is
the bow thruster battery located behind the helm table. Over-current protection is provided by a
50A fuse located on the bow thruster battery. This system is compatible with multiple steering
stations and the use of an autopilot. Refer to the owner’s manual in your owner’s packet for more
information.

ASHDOWN
To operate the raw water washdown, open the seacock with the washdown I.D. tag located in
the forward bilge beneath the sole floor rigging lid. Depress the raw water switch on the accessory
switch panel. This system will now be pressurized at the raw water washdown outlets, located
port side at the aft and bow. A hose with a spray nozzle attached may be used intermittently
without turning the switch off in the same fashion as a home yard hose with a nozzle. The raw
water pump has an internal pressurization switch that will maintain water pressure as needed until
the switch is turned off at the switch panel. The pump is located in the forward starboard rigging
compartment and may be accessed via the access panel in the aft storage area under the helm. See
“Livewell/Raw Water Washdown System Layout” on page 8–29 for a system diagram.

EFRIGERATOR
The refrigerator is a double drawer design that includes a refrigerated top drawer and a frost
free freezer and integrated ice maker in the bottom drawer. This unit operates on AC power only,
requiring either the generator to be in operation or the shore power to be connected with load
group 1 energized. To power up the unit, the refrigerator switch on the AC panel must be on as
well as the ON/OFF button on the right side of the digital control panel located in the top drawer.
The digital control panel also allows you to set the desired temperature of the refrigerator,
temperature of the freezer, and operate the ice maker.
The ice maker produces ice using water supplied by the boat’s freshwater system. Therefore,
the freshwater switch on the DC panel must be on, or the boat must be connected to a shore water
supply for the ice maker to function. A valve is installed inline with the freshwater supply to
provide water to the unit and to serve as a means for winterizing the system. This valve is set in
the winterized position (perpendicular to the supply line) at the factory. A 4” screw out plate
located in the galley trash can storage compartment provides access to this valve. This valve must
be turned parallel to the supply line prior to using the ice maker.
To winterize the ice maker, turn the valve perpendicular to the supply line allowing the small
amount of water in the ice maker line to drain out through the valve and into the bilge. Then cycle
the ice maker one time to remove any remaining water from the unit.
For additional information regarding troubleshooting, maintenance, or defrosting, please
reference the refrigerator user’s manual in your owner’s packet.
