simultaneously with the engines running. If the boat has triple engines, the center switch may be
set in position “1” or “2”. The fifth battery forward in the boat receives charge from an engine
isolator lead (from the center engine on a triple, and the port engine on a dual). For emergency
situations when neither battery bank alone will start the engines, select “1” & “2” on each switch.
Return the switches to normal operation settings after starting the engines.

Your boat is equipped with automatic float switches adjacent to the bilge pumps. A float
switch will enable the pump to come on automatically if a significant amount of water
accumulates in the bilge. The float switches function independently of the battery select switches
and can activate the bilge pump with the battery select switches in the “off” position. The bilge
pumps are also equipped with switches at the helm. When a switch is in the “on” position, the
pump will run continuously. The pump should not be left in the “on” mode unless someone is
monitoring the system and can turn the pump off when the bilge is dry. When a switch is in the
“off” position, the pump is off unless activated by the float switch.

Your boat has two bilge pumps. One is located in the aft bilge rigging compartment and can be
accessed through the aft rigging lid beneath the access panel in the generator subfloor. The second
is in the rigging compartment under the access panel located on the floor of the helm area. See
“12 Volt DC Accessory Locations” on page 8–40 for a layout of all 12 volt DC accessories.

HRUSTER
(not necessary with Yamaha Helm Master™ control option)
The bow thruster aids in maneuvering your boat. The outboard engines can control the
direction of the stern while the bow thruster moves the bow. Use the joystick control located at the
helm to control the thruster. The emergency shut-off switch provides a simple method to quickly
disconnect power from the thruster motor. Depress this button to disengage the thruster in the
event of an emergency. Reference
“Bow Thruster & Power Assist Layout” on page 8–37 for a
layout diagram.
W A R N I N G
Never turn the battery select switch to the “off” position with an engine (including generator)
running as this could damage the engine charging system or the diesel generator’s control panel.
C A U T I O N
To prevent damage to the bilge pump, do not run it dry for a prolonged period of time.
C A U T I O N
To avoid damaging the sheer pin in the bow thruster lower unit, do not engage the thruster when
the propeller is not submerged. Also, do not suddenly change direction of thrust without allowing
the propeller time to stop.
