2011 Four Winns V335 Boat Owners Manual

Moving the trim tabs downward will increase the lift
and the boat will achieve plane faster, or stay on plane
at a lower engine and boat speed.
to constantly monitor the operational condition of the
engine. Close observation of these instruments could
save the engine from damage.
After gaining plane and establishing cruising speed,
pressing both lower trim tab switches will cause both
trim tabs to move upward and will allow the bow to
rise. This should be used to adjust the running attitude
of the boat to decrease the drag at cruising speed or
above, or when running in a following sea.
The V335 models have individual gauges
in the dash panel as standard instrumentation.
See Figure E5.
When running at an engine speed that results in the
boat falling off plane or causes the boat to plane
inefficiently, lowering both tabs slightly (bow down)
will improve the running angle and improve operating
Optimum efficien cy is obtained when operat ing at a 3
to 5 degree running angle. Utilizing too much “Bow
Down” trim tab can reduce operat ing effi ciency and
cause substan tial stee ring and handling difficul ties.
Be extremely careful when running in a following sea.
The effect of trim tabs is ampli fied under such condi-
tions. Steer ing and handling difficulties can result from
improper trim tab usage, especially in a following sea.
If unsure of proper trim tab positioning, raise the trim
tabs to the full-up position.

A.   Tachometer
The tachometers indicate the speed of the engines in
revolutions per minute (RPM) and are preset by Four
Winns. This speed is not the boat speed or necessar-
ily the speed of the propeller. They may not register
zero with the ignition key in the OFF position. Note:
The V335 models come with a tachometer/hour meter
combination gauge which allows for hour meter
viewing at the helm. Please refer to Section
When running at high engine speeds, be sure
the trim tabs are in the full up position. Trim tab
action should be only enough to compensate
for any listing. Trim tab adjustments at high
speeds are extremely critical. Be prepared to
slow down should handling difficulties arise.
E-9J - Engine Hour Meter for information regarding
the engine hour meter.
When running in a displacement (very slow speed)
mode, better efficiency will be obtained with the trim
tabs in the full-up position.
Never exceed the maximum recommended
operating RPM of your engines. Maintaining
maximum, or close to maximum RPM for
extended periods can reduce the life of the
C.   Trim Tab Maintenance
Check the fluid level of the trim tab reservoir often.
Always keep the fluid level between the designat ed
marks on the trim tab pump-reservoir. Refer to the
manufacturers information for specifi cations on the
type of fluid to be used and other operation and
maintenance information.
Some engines are equipped with devices that limit
engine RPM in accordance with the oil pressure or
engine temperature. Refer to the engine owner’s
manual for additional information.
The tachometer must be set for different engines
installed. This is typically done at the factory. The
tachometer gauge is shown along with the table
detailing the tachometer settings. See Figure E6.
The helm station is equipped with a complete set of
engine instruments. These instruments allow the pilot
