2011 Four Winns F-Series Boat Owners Manual

An engine that is not developing full power and the load
carried in a boat will directly affect performance of the
engine. Always be sure the engine is properly tuned
and load conditions are those normally experienced,
before changing propellers.
For additional information on factors affecting perfor-
mance, please consult your Four Winns dealer.
Boat Properly Trimmed
Boat Too High - Trim Bow “Down”
Hull planing surfaces have the least amount of drag
at a three to five degree angle with the water. This is
the preferred running angle when boating. The run-
ning angle has a signifi cant impact on top speed and
handling. See Figure E-2. Heavy load or certain water
conditions may make it difficult to achieve the optimum
running angle. The running angle can be controlled
through the use of the power trim.
Boat Too Low - Trim Bow “Up”
Figure E-2:  Running Angle
A.   Power Trim
Trim angle is how far in or out, the drive is positioned
in relation to the bottom of the boat. The trim angle of
the drive has a distinct affect on the running angle
of the boat.
E - 6    TRIM TABS
Electric/hydraulic trim tabs are available on certain
models.  Check with your dealer for availability on
your  model. Trim tabs help provide maximum control
of the hull in all water and load conditions. Used
properly, trim tabs can:
The power trim system permits control of the trim angle
of the drive relative to the boat, at the touch of a button.
It allows the drive to be raised for shallow water opera-
tion. Power trim also allows the operator to adjust the
drive while underway to provide the ideal running angle
for a given load and water condition. Additional infor-
mation can be found in the engine operator’s manual
included in the owner’s packet.
a.   Compensate for wind and load listing (level the
boat side to side).
b.   Induce faster planing and help achieve optimum
running angle (see Section E-5 - Running Angle
Power Trim/Tilt).
B.   Power Tilt
The proper use of electric/hydraulic trim tabs requires
a basic understanding of trim tab operation and some
practice in calm water. Be sure to read the manufac-
turer’s literature included in the owner’s packet.
Power tilt allows the operator to raise and lower the
drive  for trailering, launching, and beaching. Additional
information on power tilt can be found in the engine
operator’s manual included in the owner’s packet.
The trim tab control uses two (2) momentary-type
rocker switches.  The trim tab switches control the
attitude or position of the boat. The trim tab switches
are labeled by position such as “Bow Up” and “Bow
Down”. They are also labeled for “Port” and “Stbd”.
When pressed, the label indicates what happens to
the bow of the boat.
DO NOT operate the motor with the water
intakes out of the water. Severe damage to the
engine systems can result. Consult the engine
operator’s manual for specific information.
