Changing either diameter or pitch will have an effect
on engine speed and prop slip, and in turn, directly
affect the performance of a boat. The propeller(s) in-
cluded with each 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, environment, the individual en-
gine and hull performance may necessitate the pur-
chase and use of another propeller(s).

If the engine(s) exceeds the recommended rpm, an
increase in pitch and/or diameter is required. If the
engine rpm is too low, a decrease in pitch and/or di-
ameter is required.
Boat Too High - Trim Bow “Down”
An engine that is not developing full power and the
load carried in a boat will directly affect performance of

B. Power Tilt
Power tilt allows the operator to raise and lower the drive
or outboard motor for trailering, launching, and beach-
ing. Additional information on power tilt can be found in
the engine operator’s manual included in the owner’s

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 han-
dling. 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.
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.

ENGINE INSTRUMENTATION
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 or outboard engine has a
distinct affect on the running angle of the boat.
Four Winns is using a new style of instrumentation pack-
age on the 180, 190 and 200 Horizon® models which
consists of a module similar to units used in the auto-
mobile industry. See Figure E3. Refer to Section E-6H
for display functions.
The power trim system permits control of the trim angle
of the drive or outboard motor relative to the boat, at
the touch of a button. It allows the drive or outboard
motor to be raised for shallow water operation. Power
trim also allows the operator to adjust the motor while
underway to provide the ideal running angle for a given
load and water condition. Additional information can
