The right Ewol propeller depends on your boat length and engine power: the E3 Andromeda suits boats from 18-36 ft (7-35 hp), the E3 Orion covers 30-60 ft (30-160 hp), and the E4 Pegasus is built for 60-100 ft yachts (160-500 hp). All three are automatic feathering propellers with externally adjustable micrometric pitch, so the choice comes down to matching diameter, shaft or Sail-Drive fit, and engine horsepower to your specific boat.
Ewol propeller range at a glance

Why does the propeller matter on a sailboat?
The propeller is the primary connection between your engine and the water, much like tires connect a car’s engine to the road. Even on a wind-powered sailboat, the propeller is essential marine equipment and should be chosen carefully. Matching it to your application maximizes engine power and improves handling, comfort, speed, acceleration, engine life, fuel economy, and safety.
Ewol propellers are automatic feathering designs: the blades orient themselves according to the flow of water under sail to reduce drag, then set the correct angle of incidence under engine power. The pitch is adjusted micrometrically from the outside using an adjustment ring, optimizing thrust so you reach high cruising speeds at a low number of revs with reduced fuel consumption.
What is the E3 Andromeda and which boats suit it?
The E3 Andromeda is the smallest Ewol propeller, a cutting-edge feathering propeller built from high-resistance stainless steel. Its slim, streamlined body suits boats from 18 to 36 feet (6 to 11 m) and engines from 7 to 35 hp. It is available with three blades in diameters from 10" to 17", in Sail-Drive or straight-shaft versions (20-30 mm / ¾-1 ⅛ in). Blade orientation is fully automatic and pitch is set from the outside via the adjustment ring.
What is the E3 Orion and which boats suit it?
The E3 Orion is built around a gear core that lets the blades follow the water’s flow while sailing and set the correct angle under engine power, improving performance both under sail and under power. It brilliantly solves the lack of maneuverability many boats suffer when reversing, especially in strong winds, tight spaces, or rough seas.
Orion suits boats from 30 to 60 feet (9 to 18 m) and engines from 30 to 160 hp. It comes with three blades in diameters from 13" to 26", made entirely of stainless-steel super-alloys for exceptional mechanical strength and resistance to galvanic corrosion; Titanium-alloy blades are also available. It is offered for the shaft line (25-40 mm / 1-1½ in) and with the FlexDrive anti-shock device for Sail-Drive, and can be installed, removed, and adjusted in minutes even with the boat in the water.
What is the E4 Pegasus and which boats suit it?
The E4 Pegasus was designed for large, luxurious sailing yachts, Maxi and MiniMaxi, generally 60 to 100 feet long with engines of about 160 to 500 hp. Its large four-blade surface area comes in diameters from 13" to 26", available with a straight shaft (45-60 mm / 1¾-2¼ in). Pegasus is offered in three versions: full Super-Duplex steel, Super-Duplex with Titanium blades, or all-Titanium.
Which Ewol propeller should I choose?
Start with your boat length and engine horsepower, then confirm your shaft diameter or Sail-Drive fit. Choose Andromeda for compact cruisers up to 36 ft, Orion for mid-size cruising boats from 30 to 60 ft, and Pegasus for large yachts of 60 ft and up. Across the range, the benefits are the same: significantly improved maneuverability, increased sail speed, optimized motor speed, easy assembly and disassembly even in the water, external micrometric pitch adjustment, and very high corrosion resistance from stainless-steel super-alloys.
Frequently asked questions
What size boat is each Ewol propeller for?
Andromeda fits boats 18-36 ft (7-35 hp), Orion fits 30-60 ft (30-160 hp), and Pegasus fits 60-100 ft yachts (160-500 hp).
Are Ewol propellers feathering?
Yes. All three models are automatic feathering propellers: the blades align with the water flow under sail to cut drag and set the correct angle under engine power.
Can I adjust the pitch myself?
Yes. Ewol propellers use a micrometric pitch adjustment made from the outside with an adjustment ring, so you can fine-tune thrust without disassembly.
Do Ewol propellers help with reverse maneuvering?
Yes. The Orion in particular is designed to solve the poor maneuverability many boats have in reverse, even in strong winds, tight spaces, or rough seas.
What materials are Ewol propellers made from?
They are built from stainless-steel super-alloys for high strength and galvanic-corrosion resistance, with Titanium-blade and all-Titanium options on the Orion and Pegasus.
Can they be installed with the boat in the water?
Yes. Ewol propellers are designed to be installed, removed, and adjusted in a few minutes, even with the boat still in the water.
