SPW 4 blades saildrive ZF SD15 Variprop for Sailing Boat

Variprop Grand Performance propellers are a new generation of automatic feathering propellers for sailing yachts. The symmetric high-tech GAWN blade profile is primarily used for high performance fixed pitch propellers in motor boats, for rudder profiles, as well as in the aviation industry. From now on, it can also be found in the new generation of the VARIPROP GP. Thanks to the GAWN profile, the newcomer on the market persuades with smooth, energy-efficient running. It is possible to decrease the average fuel consumption by up to 10% due to higher thrust, depending on the number of propeller blades. They are made of NiBrAl bronze that is the best material for propeller manufacturing. It is called Ice Class in professional shipping and has excellent bearing properties. This is why our VARIPROP bearings are made out of NiBrAl bronze in the most sensitive sections, especially where parts move while shifting from ahead to reverse and viceversa during manoeuvres. VARIPROP GP 4-Blade is pure power for offshore sailors. These propellers provide highest convenience on board and reliability in all kinds of weather. Very high thrust and smooth running even with the strain of heavy weather zones. The fourth blade minimises blade pressure and cavitation at the propeller blade with a greater engine output.This achieves very good sailing properties due to low drag and perfection of manoeuvres. Furthermore, it ensures a successful outcome of every harbour manoeuvre even in the most adverse wind conditions. Suitable for ZF SD15 saildrive. Also available for other saildrives, check out the full range on our website.
