VARIFOLD folding propeller
A true all-rounder
All versions of VARIFOLD folding propellers use inertia and hydrodynamic forces to open the blades reliably, giving a quick response, ahead & astern.

- Modern blade design with substantial blade area for smooth running and minimum noise & vibration
- Rubber bump stops minimise blade opening impact
VARIFOLD 3-Blade
- Diameter 432mm to 813mm or 16” to 32”
- For engines rated to 350HP
- Available for shafts & saildrives
- Latest blade design incorporates high skew and cambered blades for smooth operation
