Propeller selection is very important in the
performance of your boat. Acceleration, speed, fuel efficiency,
stability and engine RPM's all are affected by the propeller selected.
Operating requirement and conditions will also affect which design,
style and pitch of propeller you may choose to meet your individual
needs. The boat and engine combination may have already been tested
by your dealer or the boat manufacturer for the appropriate propeller
size. Your Suzuki Dealer can assist you with the process to determine
the correct propeller for you application.
Stainless Steel Propellers offer higher performance and greater
durability than aluminum propellers. The aggressive design of
these propellers enhances the overall performance of your boat
and the durability of the stainless steel constructed will give
you long term dependability. Your Suzuki Stainless Steel propeller
is also fitted with a rubber cushion hub to help absorb vibration
and shock should you strike a foreign object.
referring to a propeller size, such as 13 X 18, the first number
details the diameter of the propeller and the second number is
the pitch of the propeller. The pitch is the most significant
number in the description. The diameter is usually predetermined
by propeller engineers and is based on the size and series of
is considered to the distance across an imaginary circle that
is made when a propeller is rotated. Diameter is determined during
the engineering process of designing a propeller and is usually
based on the requirements to meet the needs of engine size, gear
case design, horsepower and speed.
is used to describe the theoretical distance that a propeller
"cork screws" through the water in inches of forward
travel. In theory, an 18" pitch propeller would move ahead
18" with each complete revolution of a propeller. There is
always some percentage of inefficiency as water conditions, boat
weight and propeller style are introduced into the performance
equation. The lower the "slip factor" the more efficiently
the propeller will perform and the faster the speed at a given
engine RPM. Lower pitches accelerate faster, but have a lower
top end speed. Higher pitches have a slower acceleration, but
may attain higher top speeds. An inch of pitch generally is equal
to 150 - 200 engine RPM's at wide open throttle (WOT). If pitch
is increased by an inch, RPM's will decrease by 150 - 200 RPM's
at WOT. If pitch is decreased by an inch, RPM's, will increase
by 150 - 200 RPM's at WOT. Always operate your boat/engine combination
within the recommended RPM range guidelines as stated in your
operators manual. Operating outside the recommended range can
cause severe damage to your engine and may void the engine warranty.
is used to reduce the slip and ventilation of the propeller. This
will allow you to operate your engine at a higher transom mounting
and allow you to use more trim for bow lift. The cup refers to
the area along the trailing edge of the propeller blade that has
an increased pitch in the last 1/2" of the blade surface
and extends to the blade tip.
is described as the angle, in degrees, that the propeller blades
are mounted to the "barrel" of the propeller. The blades
of a zero degree rake propeller are mounted perpendicular to the
"barrel" of the propeller. The blades of a higher rake
propeller angle more to the rear of the propeller. A propeller
with a high rake design will fold the water on the blades longer
during operation and will ventilate less at higher engine heights.
High rake propellers will produce higher thrust that will life
the bow of the boat more effectively.
These help provide theft protection
for your boat's propeller, in and out of the water. Constructed
of naval brass and stainless steel for long life. East to install.
Also fits counter rotation models.
