Running Angle & Power Trim/Tilt; Power Trim; Power Tilt; Trim Tabs - Four winns FREEDOM Owner's Manual

Four Winns® boat provide the best general performance
based on data obtained from on-the-water testing of that
model. Variations in load, operating conditions, envi-
ronment, the individual engine and hull performance may
necessitate the purchase and use of another propeller(s).
Under your normal load conditions the engine(s) should
turn within the maximum rpm range when at full throttle.
If the engine(s) exceeds the recommended rpm, an in-
crease in pitch and/or diameter is required. If the en-
gine rpm is too low, a decrease in pitch and/or diameter
is required.
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.
E - 5 RUNNING ANGLE & POWER
TRIM/TILT
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 running angle
has a significant impact on top speed and handling.
See Figure E2. 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.
A. Power Trim
Trim angle is how far in or out, the drive or outboard
motor 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.
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.

B. Power Tilt
Power tilt allows the operator to raise and lower the drive
for trailering, launching, and beaching. Additional infor-
mation on power tilt can be found in the engine operator's
manual included in the owner's packet.
NOTICE
DO NOT operate the motor with the water in-
takes out of the water. Severe damage to the
engine systems can result. Consult the engine
operator's manual for specific information.

TRIM TABS

Electric/hydraulic trim tabs are available on certain
models. Trim tabs help provide maximum control of the
hull in all water and load conditions. Used properly, trim
tabs can:
a. Compensate for wind and load listing (level the boat
side to side).
b. Induce faster planing and help achieve optimum run-
ning angle (see Section E-5 - Running Angle & Power
Trim/Tilt).
