Streamline IA Aluminum Propeller for Waydoo

High-Efficiency Aluminum Propeller Upgrade for Waydoo eFoils

This propeller is designed for the older Waydoo efoils.  If you need a prop for the Waydoo EVO line, click here.

The EfoilSolutions Streamline IA Aluminum Propeller is a performance propeller designed to improve efficiency, speed, and durability for Waydoo eFoil riders. Developed by Streamline 3D and tested by experienced riders, the Streamline IA has shown improved performance in key areas such as noise levels, propulsion efficiency, and top speed compared to several standard Waydoo propeller options.

This aluminum version builds on the original Streamline I propeller design and provides greater durability and efficiency, making it a popular upgrade for riders who want to get more performance out of their Waydoo setup.

Why Upgrade Your Waydoo Propeller?

The propeller plays a major role in how an eFoil accelerates, cruises, and consumes battery power. A more efficient propeller can improve ride time, reduce noise, and provide smoother thrust.

Testing has shown that the Streamline IA propeller can deliver 15% to 26% higher efficiency compared to several other Waydoo propeller options and propulsion systems.

In addition, it has been reported to outperform the Waydoo folding propeller in both efficiency and top speed.

Key Performance Benefits

Improved Efficiency

A streamlined blade design converts more motor power into thrust, which can improve battery efficiency and ride time.

Higher Top Speed

The propeller has demonstrated faster top-speed performance compared with several other Waydoo propeller designs.

Quieter Operation

Testing shows the propeller performs well in terms of reduced noise and smoother thrust delivery during operation.

Durable Aluminum Construction

The aluminum version of the Streamline propeller offers improved durability compared with earlier versions while maintaining strong hydrodynamic performance.

Compatibility

This propeller is designed for Waydoo eFoil systems, including models in the Flyer series.

Propeller kits are available for:

• Flyer ONE Plus

• Flyer ONE with upgrade kit

• Other Waydoo Flyer models

Depending on your setup, you can purchase either:

• the complete prop kit (cone, propeller, and cap), or

• the propeller and cap only if you already own a Streamline I kit.

Important Installation Note

The Streamline IA propeller is intended to be used without the standard propeller guard (shroud). A replacement cone can be used to create a smooth transition around the motor housing when the shroud is removed.

Real-World Performance Example

During testing under calm conditions with a 170-lb rider, a Waydoo equipped with this propeller setup achieved over two hours of ride time on a single battery charge, demonstrating the efficiency gains possible with optimized foil and propeller combinations.

Who This Propeller Is For

The Streamline IA propeller is ideal for:

• Waydoo riders seeking better efficiency and ride time

• riders wanting higher top speeds

• riders looking for quieter propulsion

• advanced riders optimizing their foil performance setup

Frequently Asked Questions

What does the Streamline IA propeller improve?

It improves propulsion efficiency, speed, and durability, which can translate to longer ride time and smoother thrust delivery.

Can the propeller be used with the stock prop guard?

No. The Streamline IA is designed to be used without the stock propeller shroud.

Is this propeller compatible with all Waydoo boards?

It is designed for Waydoo Flyer series eFoils, with different kits depending on the model.

We recommend purchasing the complete kit, which includes the cone, prop, and cap, as detailed below. If you already own Streamline I kit, you will only need to purchase the prop and cap.

Please read safety instructions for this propeller.

This propeller must be used without the prop guard (shroud).  A modified cone to replace the prop guard is available here.
