Propellers
Volvo Penta makes a complete line of propellers designed
to match the performance of the SX, DP, DPX, and XDP
sterndrives. For every combination of engine, sterndrive, hull,
and application there is a Volvo Penta propeller that pro-
vides optimum performance.
Many factors influence the way a propeller performs, includ-
ing hull shape, onboard weight, engine horsepower, power
trim, and the way the boat is used. Ask your Volvo Penta
dealer to assist you in choosing a propeller that is right for
your needs.
Propeller Selection
The propellers for the Duoprop drive units have application
and diameter/pitch identification symbols: D0-D7, and F2-F9.
The single number represents the diameter/pitch. The iden-
tification symbol and the front and rear identification are
stamped on the end of the propeller hubs. When replace-
ment is required, you may purchase the propellers individu-
ally, but you must make sure they are the same size and
same shaft (e.g., F7 front and rear). Do not mix or split sets.
“D” series aluminum propellers
Volvo Penta’s aluminum propellers are manufactured with a
special aluminum alloy that is highly resistant to the stress
and effects of salt water. The unique design of the Duoprop,
with its two counter rotating propellers, is very important in
achieving optimum performance.
Note:
D5, D6, and D7 propellers are recommended for
speeds below 40 MPH. For installations where “D”
series propellers are not recommended, “F” series
stainless steel propellers should be used.
“F” series stainless steel propellers
A stainless steel Duoprop set is a very worthwhile upgrade
from aluminum. They offer high performance through thin-
ner blades, powerful thrust, and virtually cavitation-free run-
ning; and greater torsion strength for higher acceleration.
“X” series composite propellers
Volvo Penta’s composite X propellers are made from impact
resistant composite material that is impervious to galvanic
corrosion effects. They offer the capability of individual blade
replacement without replacing the entire propeller assem-
bly. The pitch can be changed by simply changing the blades
without having to purchase the complete propeller hub
thereby reducing cost. These propellers range from X-3 to
X-8. If changing propeller pitch, both front and rear propeller
blade sets must match. Do not mix different pitch propellers.
Caution!
X-series composite propellers are not designed to be
utilized on 5.7 liter engines. The 5.7 OSi and OSXi devel-
ops more power than these propellers are capable of
handling. Serious damage will result to the propeller
blades and possibly the drive.
