Autoprop is unique! This remarkable propeller can be found on thousands of sailing yachts the world over! Fitted to all the BT Challenge yachts, and tested in the most arduous conditions, Autoprops benefits for cruising yachts are unmatched by any other product. Considerably reduced drag can be expected from most feathering propellers but unlike ' the others' Autoprops exclusive design enables her shaped blades to automatically find the optimum pitch when motoring or motor sailing, ensuring excellent performance both ahead and astern, with virtually no 'prop walk'.
Faster motoring speeds for the same revs; better economy using lower revs at a yachts normal cruising speed; as much as one knot increase in sailing speed and a huge advantage when motor sailing, unachievable by any other feathering propeller: -
Autoprop automatically adopts the most efficient pitch setting, taking into account the driving force of the sails. The result is increased speed at lower revs, giving longer range and more comfortable cruising.
Too good to be true? There is lots more to be discovered on this web site about this great propeller range, which offers two and three blade versions plus one suitable for sail drives, and Autoprop sizes will accomodate any engine up to 350hp.

An innovative new propeller for sailing yachts ...
The Kiwiprop™ is a unique cost effective feathering propeller that eliminates gears, aligns the blades with the streamlines not the shaft, minimises corrosion potential from the lightweight composite blades and offers users easy variable pitch adjustment. In the Kiwiprop™ the individual blades are always free to "weather vane" in the actual water flow, to a minimum drag position so don't cause autorotation.
This modern light weight three bladed feathering propeller has proved much smoother and quieter in operation than equivalent two bladed units and offers the additional benefits of variable pitch, fully lubricated, minimal corrosion potential and the full reverse thrust.

The Type FR is a fixed adjustable propeller, and is the best choice when you do not know which propeller is the best for your boat, when a suitable fixed propeller is hard to find, or when there are special requirements to the propeller.
The Type FR propeller is easily adjusted to optimum pitch using two wrenches. Adjusting the propeller to optimum pitch ensures a correct load on the motor, while also providing maximum power and fuel efficiency. In addition, the cost of a Type FR propeller is low compared to buying several fixed propellers in order to find the best one for your application. The Type FR propeller has approximately the same efficiency as a fixed propeller, in some cases even exceeding the fixed propeller's efficiency. When adjusted, it is used in the same way as a fixed propeller.
Fixed adjustable propellers are used for all types of boats, and usually have three or four blades. West Mekan calculates and produces these propellers in diameters of up to 1500mm, for speeds up to approximately 40 knots.
Fixed adjustable propellers with more or fewer blades can be specially designed.

SCHOTTEL controllable-pitch propellers (SCP), manufactured by SCHOTTEL-Schiffsmaschinen GmbH (formerly WPM), are propulsion systems that can be used with almost any type of vessel. The power spectrum ranges from 600 kW to 30,000 kW, with propeller sizes varying between approximately 1.5 to 8.0 metres.
Advanced calculation methods allow the controllable-pitch propeller systems to be optimally adapted to the vessel’s hull form, thereby maximizing efficiency and minimizing noise generation.
The simple structure of the SCP guarantees a high level of user-friendliness, and the robust design keeps maintenance requirements to a minimum and ensures it a long service life.

When using a controllable pitch propeller it is always possible to optimize the motor and propeller to current payload, wind and water resistance. The results are low fuel consumption and proper motor load, as well as good manoeuvering qualities.
Controllable pitch propellers are used for all types of boats, and usually have three or four blades. West Mekan calculates and produces these propellers in diameters of up to 1500mm, for speeds up to approximately 40 knots.
Fixed adjustable propellers with more or fewer blades can be specially designed.

The propeller hub
The propeller hub is made of nickel- aluminum-bronze and is attached to either a flanged shaft or tapered end shaft, depending upon the system size. The propeller blades are moved by a tie rod cross head with stainless pins.
On each pin a movable slipper block is mounted in a milled slot in the blade foot.
The propeller head is lubricated with water emulsifying grease.
The mechanism of the propeller head consists of simple mechanical parts.
The propeller blades
The blades are made of nickel-aluminium-bronze in 2, 3, or 4 bladed design. They are designed for open running and propeller nozzles, as well as for feathering position.
