Trim Tabs
Trim tabs control the longitudinal and lateral trim of your boat at cruis-
ing speeds and are controlled by two rocker switches, located at the helm
station. Before using the trim tab switches, we strongly urge you to read
and understand the trim tab operation manual included in your yacht’s
owner’s packet and observe the following:
•
Once the best bow cruising trim is reached, use the port or starboard
trim switches, one at a time, to correct unequal lateral loading.
•
Trim tab adjustment should be performed by several short touches to
the switch rather than one long one. After each short touch allow about
five seconds for the hull to react.
•
The trim tab hydraulic fluid reservoir is located in the engine compart-
ment. The fluid level should be checked periodically (at least once a
year) and refilled as necessary.
B i l g e P u m ps
•
Your yacht is equipped with three auto-
matic impeller-type bilge pumps which
are used to pump water out of the bilge.
•
Bilge pumps are controlled by auto-
matic bilge pump float switches
(autofloat switches) and/or switches
at the helm.
•
Bilge pumps are wired directly to the
battery so they will function even when
the yacht is completely shut down and
left unattended.
Bilge Pump Testing
Bilge pumps should be tested often to verify that they are working properly. To manually test a bilge pump’s opera-
tion, activate the dash-mounted switch and verify that water in the bilge is pumped overboard. If bilge water is
present and the pump motor is running but not pumping, inspect the discharge hose for a kink or collapsed area. If no
problems are found, check the bilge pump housing for clogging debris as follows:

LOSS OF CONTROL HAZARD!
•
Improper use of trim tabs may cause loss of control! DO NOT use trim tabs in a following sea

NEVER allow anyone unfamiliar with trim tabs to operate them and DO NOT use trim tabs
to compensate for excessive unequal weight distribution.
