Flexofold Composite Propeller 19" X 3 Blade

19" Flexofold 3 Blade Composite Propellers for Volvo Penta, Yanmar, Lombardini and Technodrive Sail drives.

The 3-blade Composite propeller for sail drive is available in diameters of 16" to 20" - all in a wide range of pitches. Available for LEFT turning sail drives (sail drives are generally LEFT turning, however catamarans might use a counter rotating propeller on one side).

Taking advantage of modern composite materials, the Flexofold Composite propeller is not only immune to electrolysis, it also features a protective torsional hub, low weight and high strength – all combined in an attractive design. The Flexofold Composite propeller still provides the recognized low drag, higher speed and good performance under sail, as well as high thrust and strong maneuverability under power.

Crafted from high-quality composite materials, this propeller is almost immune to electrolysis, making it an ideal choice for saltwater environments. It offers long-lasting durability, even in challenging marine conditions. A common issue for sailboat owners is electrolysis – caused by electrical errors in the sailboat or shore power. Today’s use of electrical equipment on sailboats increases the risk of wrong installations. Even if all installations are okay, docking in a marina with defective shore power can cause severe damage, as stray currents easily damage the propeller – which is normally the part with the best electrical connection into the water.

The Flexofold Folding Sailboat Propeller is the most efficient, lowest drag propeller you can buy. This claim is based on independent tests conducted over the past several years and reinforced today by sailboat builders and owners around the world.

Special Features of the Composite Propeller: 

• Composite material immune to electrolysis
• Light weight (2 kgs less than our standard 3-blade folding propeller)
• Helical gearing between the blades ensures a synchronized folding mechanism.
• The patented mounting system absorbs impact from the centrifugal force and allows adjustment of play in gears.
• Protective cover over the gearing
• Shock absorbers for quiet opening of the propeller.
• A special inner hub to protect the sail drive and gearbox from the propeller impact.
• Mounting screws are pre-applied with Loctite for mounting above as well as under water.
• Water lubricated - no need for maintenance.
  

The Flexofold Propeller does work with a hydraulic transmission. However, to get the prop to fold, you have to follow a simple procedure. The objective is to stop the rotation of the prop which is easily done with a mechanical transmission by putting the gear in reverse. With the mechanical transmission, the clutch stays engaged, and the prop can’t turn. With the hydraulic transmission, the clutches stay engaged only as long as there is hydraulic pressure being produced by the turning engine. When the engine is turned off, the clutches disengage and the prop is free to spin no matter where the transmission is. With the blades open and the boat moving forward, centrifugal force will keep the blades open unless you can stop the rotation for a moment while moving forward, forcing the blades to fold. Once folded, the blades will not reopen without rotating the engine again. To cause the Flexofold to fold with a hydraulic transmission, follow the steps below:

1. With the boat moving forward and the motor running in forward (the sails can be up, too) idle down and shift to reverse.

2. Immediately after putting the engine in reverse, shut the engine down. By putting the engine in reverse, you stop the rotation in the forward direction and the blades will fold because you are still going forward. After the engine is shut down, the blades remain folded until you restart the engine and put it in gear.
