feathering propellers SPW Variprofile

The new feathering propellers SPW Variprofile is the perfect feathering propeller for boats and yachts with engines up to 75 hp.
Mounting a VARIPROFILE under your boat does not require an engineer. Pitches are pre-set at the factory to the theoretical optimum and easily understood installation instructions are provided.
When the engine is switched off, the blades automatically turn into sail position due to the water flow.
When switching to reverse, a slight rotation of the shaft causes the leading edge of the blades to rotate 180°.
The feathering propellers SPW Variprofile, with optimal pitch adjustment, not only provides more thrust in forward and reverse than other propellers, but amazingly also uses less fuel doing so.
