4-Blade Shaft Folding Propeller


4-blade shaft propeller

A powerful hydrodynamic design that ensures efficiency


The 4-blade Flexofold folding propeller provides trouble-free handling and superior power in both forward and reverse. The powerful hydrodynamic design provides efficient use of the engine. Despite the relatively large propeller and 4 blades, the low drag makes your boat sail faster and allows the sails to stay up even in very light wind.

Original and correct propeller for Beneteau, Hanse Yachts, Sunreef Catamarans and more!​ 




Danish quality

All Flexofold propellers are designed and manufactured in Denmark in our single-purpose factory, equipped with modern CNC equipment and robot technology.

In 2017 Flexofold was acquired by Yanmar Marine International. However, Flexofold is still operating from the factory in Denmark, maintaining own distinct brand identity and remaining a Danish registered company.

The propellers are sold directly to boat builders as well as private boat owners worldwide. Due to our flexible production setup, we can manufacture and ship worldwide within a few days.
