The development of underwater thrusters is no longer just about increasing thrust.

For users of SUPs (stand-up paddle boards), kayaks, inflatable boats, and belly boats, what matters more today is not only power, but also efficiency, speed, durability, and overall riding experience.

This is the reason APISQUEEN developed the S10 underwater thruster.

The S10 is not a simple upgrade of an existing model. It is a completely re-designed propulsion system, built from the ground up with improvements in structure, materials, hydrodynamics, and usability.

Its goal is not only to deliver stronger thrust, but also to provide a smoother and more efficient boating experience.

Thinking from Water Flow, Not Just Power

Many people believe that the performance of a thruster mainly depends on motor power.

In reality, true efficiency comes from the entire hydrodynamic system, not just the motor itself.

How water enters the propeller, how it flows through the system, and how the blades convert energy into thrust all directly affect performance.

That is why the S10 adopts a pulling propeller design.

Unlike traditional configurations, the propeller is positioned to face the incoming water flow first, guiding water more smoothly through the propulsion system. This improves efficiency and enhances stability during cruising.

Because of this design, the S10 must be installed with the propeller facing the bow of the boat, which is an essential part of its hydrodynamic structure.

Optimized Propeller Blade Design

The propeller blades of the S10 have been specially redesigned to improve water flow efficiency.

The blade geometry and inlet flow path have been optimized to reduce energy loss caused by the intake grid, allowing more motor power to be converted into effective thrust.

For users, this results in smoother acceleration, more stable output, and a more comfortable cruising experience.

Angled Water Intake Grille to Reduce Weed Blockage

Anyone who has used a thruster in lakes or rivers knows that aquatic plants can be a major issue.

When weeds get trapped in the intake, performance drops and cleaning becomes necessary.

To improve this, the S10 features an angled intake grille design.

Compared to traditional straight grids, this structure allows weeds to pass more easily with the water flow, reducing the risk of clogging and ensuring more stable operation in complex environments.

While no thruster can completely eliminate weed interference, this design significantly improves reliability in real-world conditions.

Aerospace-Grade Aluminum Body for Durability

A high-performance thruster must also be built to last.

The S10 body is made from aerospace-grade aluminum alloy, treated with anodized surface protection.

This combination provides both high strength and excellent corrosion resistance while keeping the overall weight under control.

For users, this means better durability, longer service life, and reduced maintenance needs.

Stainless Steel Propeller for Long-Term Reliability

The propeller blades are made of stainless steel, offering higher strength and wear resistance compared to standard materials.

This ensures stable performance even after long-term and high-frequency use.

For users who rely on consistent performance, this is a key advantage.

Modular Design for Easy Maintenance

Maintenance is an important part of long-term product usage.

The S10 adopts a modular structural design, making disassembly and maintenance easier and more efficient.

Whether it is routine cleaning, inspection, or part replacement, the modular system simplifies the entire process and reduces downtime.

Designed for High-Speed Cruising

Beyond durability and efficiency, the S10 is also designed with speed performance in mind.

With a 24V 1000W brushless power system, the thruster delivers up to approximately 8.5kg of thrust, providing stable and continuous propulsion for lightweight watercraft.

From lake cruising to river exploration, or simply reducing paddling effort during long trips, the S10 delivers a smoother and more effortless experience on the water.

Who Is the S10 For?

The S10 is ideal for:

• SUP (Stand-Up Paddle Boards)

• Kayaks

• Inflatable boats

• Belly boats (fishing float boats)

• Small recreational boats

Whether for fishing, exploration, water photography, or leisure cruising, the S10 provides reliable and efficient auxiliary propulsion.

More Than a New Product — A New Design Philosophy

For APISQUEEN, the S10 is not just another product in the lineup.

It represents a new way of thinking about lightweight underwater propulsion systems.

From the pulling propeller design and optimized blade structure, to aerospace-grade aluminum housing, angled intake grille, stainless steel propeller, and modular construction — every detail is designed with one goal in mind:

to make propulsion more efficient, control more natural, and the product more durable.

We believe a great thruster should not only perform well on paper, but also deliver a noticeably better experience every time it is used.

If you are looking for a propulsion system that combines speed, efficiency, durability, and ease of use, the S10 is a new option worth considering.
