Type D, F, I, Straight Spline Duo Prop Propellers:
The patented blade geometry and large active propeller diameter provide optimal performance and fuel efficiency over the entire speed range as well as smooth running, excellent grip and maneuverability. Squeeze casting and special high-strength aluminum alloy makes them stronger and more durable than traditional die-cast propellers. Four layers of paint ensure excellent anti-corrosion performance. Engineered to optimize performance, durability and comfort with patented blade geometry, large active propeller diameter. Strong and durable high-strength aluminum alloy the I series propellers offer a three-blade front and four-blade rear propeller. Type D propeller sets are replaced by type I propeller sets. However, Type D propellers (front and rear) are sold individually as spare parts.
The F series Duo Props are the perfect upgrade for enhanced performance, strength and durability. They provide better acceleration and higher top speed due to greater strength and thinner blades - versus a comparable aluminum propeller. The high-strength stainless steel adds excellent durability and corrosion resistance. Complete with shock-absorbing rubber bushing and galvanic isolation makes it perfectly matched for the DPS-drive and the ultimate choice for demanding boaters. Enhanced acceleration and top speed versus a comparable aluminum propeller. Excellent strength, durability and corrosion resistance. Galvanic isolation protects the drive from corrosion caused by the propellers. Shock-absorbing rubber bushing reduces vibrations and stress on the drive-train.
