Eco Power - Sail Drive

What is it

The Eco Power Sail Drive propeller is available for all engines offered on the market and represents the evolution of the tried and tested Classic JPROP.

Like the latter, it is designed with a symmetrical section and profile to obtain perfect balance on the hydrodynamic centre of pressure.

The innovative shape of the blades offers an important advantage in terms of thrust efficiency and consequent reduction in consumption. Suitable for any type of Sail Drive foot, it is configured in the VOLVO SD, LOMBARDINI SD, YANMAR SD, SONIC, ZF versions.

J Prop – The self-adjusting variable pitch propeller

The advantages of J Prop are well known to all sailing enthusiasts:
- The ability to vary the pitch;
- The design of the blades, designed to minimize drag under sail;
- The significantly higher performance in reverse, compared to conventional propellers, thanks to the automatic rotation of the blades of 180°

The latest generation

J Prop is the ideal propeller for sailing boats, both for cruising and racing. Conceived and designed specifically for sailors, it is easy to install, easy to adjust, resistant and efficient

The absence of vibrations

The absence of vibrations J Prop is statically and dynamically balanced by electronic control to achieve vibration free operation.

The body

Made in cast aluminum/bronze alloy. It is mechanically worked on CNC machining centers to ensure the highest quality components.

The ogive

It is built in aluminum/bronze alloy, with reference notches for pitch adjustment and removable terminal in electrolytic zinc for absolute protection of the propeller against corrosion.

Central hub

Suitable to contain the different types of Sail Drive System.

 

The conical couples

With helical teeth, they protect against any inconvenience even with the application of high powers.

MARINE PROPELLER INTERNATIONAL PATENT FOR PROPELLERS WITH COUPLINGS

The Sail Drive model J Prop propellers also exist in a version with flexible coupling (SDB). This version was developed because there are stern-drive strength issues on the market.
The coupling system, internationally patented by Marine Propeller, is able to effectively cushion abnormal accelerations in the event of sudden maneuvers or small bumps, avoiding consequences for the transmission system.
The coupling version boasts two models:

  • SDP: fits small engines up to a maximum of 56 hp;
  • SDB: available for engines up to 120 hp.


Even Yanmar Marine International has tested two J Prop propellers with “sd20” and “sd50” couplings, the results obtained show that “SDB” and “SDP” are products with technical characteristics compatible with the Yanmar guarantee.
