COMPLETE DUOPROP PROPELLER SET (X4) 3861627 Composite Replaceable Blade Propellers for Volvo Duoprops Thru-Hub Exhaust Replaceable Blade Propellers for XDP and DP-S Drives The X-Series Composite DuoProp® Propeller is perfect for Volvo Penta 4.3L and 5.0L gasoline engines with XDP or DPS DuoProp Sterndrive. This propeller features a tensile strength 10 to 15% greater than aluminum, with performance to match. This composite material will not corrode or suffer cavitation burning the way stainless and aluminum props can. Composite construction also provides the ability to change blades too, dramatically reducing repair time and costs. Based on the Piranha Propeller concept, this prop features easily Replaceable blades * Owner repairable, no repair shop required * Blades are inexpensive to replace and easy to store * Less boat storage space than an entire spare propeller Repitchable By changing blade sizes, you can customize your boat for the day's specific activity - a lower pitch for waterskiing, and a higher pitch for cruising. Different sizes are provided for different needs. Impact Protection The X-Series Propeller is constructed of Verton®, which is made primarily from long-fiber, fiberglass and nylon, and has a high tensile strength 10 to 15% greater than aluminum. The blades are designed to absorb impact energy generated by a heavy propeller strike. This feature protects the lower unit from internal damage, and could save you hundreds even thousands of dollars in repair costs. Unlike aluminum or stainless steel propellers, the X-Series Propellers do not corrode or promote electrolytic corrosion in the boat or sterndrive. Experience fewer problems and added pleasure for leisure boating. The hubs have a core of high-strength extruded aluminum covered with Verton®. A complete propeller consists of few parts and is easy to assemble and replace. X-Series Propeller sets come complete with a front propeller nut which is required when installing on an XDP or DPS sterndrive. Excellent performance X-Series Propellers deliver performance fully comparable to that of aluminum propellers. In a recent test, the composite propeller fared as good or better than stainless propellers in acceleration comparisons.
Pitch Selection
Macomb Marine Parts and Accessories primary objective is to achieve the best performance from your boat. Macomb Marine Parts and Accessories recognizes Piranha Propellers "Blade Exchange Program". This program allows you to test and exchange undamaged blades until you are satisfied with the performance of the product. Please click here to exchange your blades.
If you are happy with the performance of your current aluminum propeller, order the same pitch in the Piranha.
If you are looking to gain speed, or lower your RPMs, increase your pitch. Every two inches higher in pitch will increase speed 3-5 mph, and decrease the RPMs by approximately 400.
If you are looking to gain hole shot, or increase your RPMs, decrease your pitch. Every two inches in pitch lower will cause you to gain approximately 400 RPMs.
If you are switching from a three blade to a four blade, drop one inch in pitch to compensate for the RPM change.
If you are switching from a four to a three blade, increase one inch in pitch.
If you have any questions about selecting the correct pitch, e-mail us and we will help determine what you need.
