If you do not wish to use this feature, you may leave the drive unit trimmed to the position that works best for you.
Propellers __________________________________________________________________
Volvo Penta makes a complete line of propellers designed to match the performance of the SX, DP, and DPX
sterndrives. For every combination of engine, sterndrive, hull, and application there is a Volvo Penta propeller that
provides optimum performance.
Many factors influence the way a propeller performs, including 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.
SX sterndrive propeller choices
1. Aluminum propellers
Volvo Penta’s aluminum propellers are die-cast and dynamically balanced. Die cast propeller
blades are thinner than sand-cast blades, which means less cavitation, greater efficiency, and
longer service life. All aluminum propellers are given added protection against salt water with a
special baked-on corrosion resistant paint.
2. Stainless steel propellers
SX stainless steel propellers will maximize the performance of SX-powered boats. The blade
configuration and through-hub exhaust design of this propeller are important factors in the
propeller’s overall efficiency and performance This is a fast planing propeller designed to give your boat better accel-
eration and top end speed. The blade design has a longer tip and larger diameter, which creates a better “grip” on the
water.
3. High performance stainless steel propellers
This propeller has custom-cupped, high rake blades to provide better bow lift and make boats plane quick and run fast
— a terrific choice for high performance boats.
Duoprop ® sterndrive propeller choices
The propellers for the Duoprop drive units have application and diameter/pitch
identification symbols: D0-D9, E2-E5, and F2-F9. The single number repre-
sents the diameter/pitch. The identification symbol and the front and rear
identification are stamped on the end of the propeller hubs. When replacement
is required, you may purchase the propellers individually, 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.
1. “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.
2. “F” series stainless steel propellers
A stainless steel Duoprop set is a very worthwhile upgrade from aluminum. They offer high performance through
thinner blades, powerful thrust, and virtually cavitation-free running; and greater torsion strength for higher accelera-
tion.
DPX sterndrive propeller choices
1. “E” series stainless steel propellers
High Performance DPX Duoprop propellers offer excellent, high speed performance with the precise handling and
efficiency that has made the Duoprop famous.
