PROPELLER SPECIFICATIONS

PROPELLER TYPES

Yamaha propellers are specifically designed to
match the characteristics of Yamaha outboard
motors.
There are some types of propellers for the best
matching depending on the operating condi-
tion.
Major types of propellers include:
STANDARD
This propeller series is designed for general
use to match a wide range of operating condi-
tions.
A stainless steel or an aluminum propeller can
be selected to suit the preference of the user.
A stainless steel, counter rotation propeller is
available for twin engine applications.
The aluminum, regular rotation propeller with
SDS (Shift Dampener
designed to match the K-series fitting boss.
System) is now
2-2
RELIANCE SERIES
New polished stainless steel propellers are
designed to provide for 150PS and bigger
standard type engines.
These propellers are generally more aggres-
sive than black standard stainless steel propel-
lers, and will fit the engines under almost all
operating conditions.
L/H rotation propellers are available for twin-
engine applications.
SALTWATER SERIES II
This new breed of stainless steel props is
designed exclusively for offshore fishing boats
and features highly polished, larger diameter
design. The aggressive rake angle and extra
cupping on the blades provide superior mid-
range fuel efficiency, along with excellent anti-
cavitation performance.
Shift Dampener System (SDS) has been
adopted to reduce the shock and noise when
shifting, and become possible to replace the
propeller damper.
L/H rotation propellers are available for twin-
engine applications.
