Blower Switch
(All Models)
A two-position switch activates the engine box
ventilation blower. Turn the switch to the right to turn
the blower ON.
Note: The blower must operate for a minimum of four
(4) minutes before starting the engine at any time. The
blower must also be operated during idle and slow-
speed running, but is not necessary during cruising
speed.
To prevent a possible explosion, operate
the blower for at least four (4) minutes be-
fore starting the engine and always when at idle or slow-running speed.
Explosive gasoline and/or battery fumes may be present in the engine
compartment. Failure to operate the blower as instructed may cause
improper ventilation of the boat engine and bilge areas, and fuel vapors
can accumulate in this area, causing a fire or explosion which may result
in serious injury or death!

Controls & Convenience
Manual and Automatic Bilge
Pump Switch
(All Models)
The bilge pumps on all V-drive models will be in the
automatic mode when the ignition key is turned ON.
Some models may have two (2) switches, one for the
forward bilge and one for the aft. In these instances,
the switches will be marked. The manual and auto-
matic bilge discharge system is never completely o.
When in the automatic (default) position, a sensor
alerts the system to discharge water from the bilge
area. Boat operators are advised to leave the switch in the automatic position, unless
there appears to be excess water in the bilge. In that event, the bilge pump can be manu-
ally activated by turning the bilge pump switch to the manual ON position. Return the
switch to the automatic position when finished emptying the bilge. Leaving the switch in
manual mode can result in damage to the pump and may not be covered by warranty!
