PROPELLER SPECIFICATIONS
SALTWATER SERIES HS4
Polished stainless steel propeller with 4-blade
for conventional V6 3.1L and 3.3L engines be-
tween 200 and 300 ps. (except VMAX series)
Compared with the conventional three blades
propeller, four blades make larger propeller
blade surface area, which can catch much
more water and obtain higher thrust perfor-
mance.
As a result, this propeller will obtain better
acceleration, and stability operation under
rough water.
However, generally boat top speed perfor-
mance is slightly behind compared with three
blades propeller.
L/H rotation propellers are available.
* Available Fall 2008
PROPELLER IDENTIFICATION
The propeller identification of the size is indi-
cated as follows.
Diameter: Diameter of propeller rotating circle.
Pitch: Logical advancing distance when
propeller rotated one time.
The location of the propeller identification var-
ies.
Refer to the illustration as shown.
Example:
(1) 7-1/4 X 6 - BS
(2) 21 - ML (Pitch - Mark)
(3) 13 X 17 - K2
(4) 19K (Pitch and Mark)
(5) 9-1/4 X 9 - J
* Calculation formula of the logical boat speed is as
below.
^ Boat speed (km/h) = propeller pitch (inch) X
engine speed (r/min) X 0.001524 X propeller
efficiency / gear ratio.
^ Propeller efficiency = Actual advancing dis-
tance when propeller rotated one time / Logical
advancing distance when propeller rotated one
time.
