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 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 or diameter is required. If the engine RPM
is too low, a decrease in pitch 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.
NOTICE
For twin engine installations, always check drive
shaft rotation before propeller installation. Aright
hand rotation propeller must be installed on the
stern drive to the starboard engine. Similarly, a
left hand prop must be installed on the port stern
drive.

RUNNINGANGLE & POWER TRIM/TILT
The power trim system permits control of the trim angle
of the drive unit  relative to the boat, at the  touch of a
button.
Hull planing surfaces have the least amount of drag at a
three to five degree angle with the water. This is the pre-
ferredrunninganglewhenboating.   Therunninganglehas
a significant impact on top speed and handling.  Heavy
load or certain water conditions may make  it difficult to
achieve the optimum running angle. See Figure B3.
It allows the drive unit to be raised (trimmed out) for shal-
lowwateroperation.  Powertrimalsoallowstheoperator
to adjust the drive unit  while underway to provide the
ideal running angle for a given load and water condition.
