AquaThruster Shallow-Water Accessory
Reduce Vortex Suction in Shallow Water
Introducing the Vortex Plate - Shallow Water Shield for the AquaThruster™!
Are you tired of dealing with the vortex phenomenon in your AquaThruster™? Say goodbye to vortex issues with our innovative Vortex Plate - Shallow Water Shield, designed to provide a seamless and efficient operation of your AquaThruster™ in shallow water conditions.
The Vortex Plate helps control the surface vortex that can form when the AquaThruster is installed close to the water's surface. By changing the way water approaches the motor and cage, the plate helps reduce ventilation, noise, and unwanted surface draw while allowing the AquaThruster to operate in shallower water conditions.

360 Oscillator Compatibility Note
*Note to owners with the Dock Post Mount with 360 Oscillator: The Vortex Plate may reduce your 360 Oscillator's rotation area.
Features
Vortex Plate Key Features
Shallow Water Install Kit
Shallow Water Install Kit: The Vortex Plate comes with a shallow water install kit that effectively eliminates the vortex suction sound, also known as ventilation. This ensures that your AquaThruster™ operates quietly and efficiently, even when installed close to the water's surface.
Versatile Compatibility
Versatile Compatibility: Although specifically designed for the AquaThruster™, our Vortex Plate is also compatible with Kasco's version of the shallow water installation kit, ensuring a wide range of usability.
Anti-Vortex Plate
Anti-Vortex Plate: The Vortex Plate's unique design works by slowing down the velocity and angles of water, allowing for a manageable and adjustable flow. This prevents the vortex phenomenon from occurring and ensures smooth operation.
Enhanced Performance
Enhanced Performance: With the Vortex Plate installed, your AquaThruster™ can now be placed in shallower water without disrupting the lake bottom or creating loud noises. This enhances the overall performance of your AquaThruster while ensuring a peaceful and tranquil environment.
Easy Installation
Easy Installation: The Vortex Plate - Shallow Water Shield is designed for quick and easy installation, allowing you to enjoy the benefits of your AquaThruster without any hassle.
How It Works
What causes an AquaThruster vortex?
A surface vortex can form when the AquaThruster is positioned close enough to the water's surface that air is drawn downward toward the propeller. This condition is also referred to as ventilation and can create a noticeable suction or swirling sound.
How does the Vortex Plate help?
The shield changes the velocity and angle of water entering the AquaThruster cage. Slowing and redirecting that flow helps prevent the concentrated surface draw that creates the vortex, allowing for smoother operation when shallow-water placement is necessary.

Compatibility
Choose the Vortex Plate That Matches Your Cage
The Vortex Plate is sold in separate model options for AquaThruster cage configurations. Select the version that matches the cage on your existing unit.
Kasco compatibility: The current product description also states that the Vortex Plate is compatible with Kasco's version of the shallow water installation kit.
Product weight: Approximately 1 lb.
360 Oscillator reminder: Owners using a Dock Post Mount with 360 Oscillator should account for the possibility that the Vortex Plate may reduce the oscillator's available rotation area.
Installation & Use
When should you add a Vortex Plate?
Use the Vortex Plate when shallow-water placement causes the AquaThruster to pull a surface vortex toward the motor or create the characteristic vortex suction sound.
AquaThruster guidance recommends keeping the motor flow just above the lake bottom rather than pointing directly into the sediment. Proper motor position helps move debris while reducing unwanted bottom disturbance.
FAQs
Vortex Plate Frequently Asked Questions
It helps reduce the surface vortex and ventilation that can occur when an AquaThruster operates close to the water's surface. This can reduce the suction sound and improve shallow-water operation.
Ventilation occurs when air is drawn from the surface toward the propeller, often creating a visible vortex and a loud suction or swirling sound.
Yes. The product is specifically designed as a shallow-water shield so the AquaThruster can operate closer to the surface with less vortexing and ventilation.
Choose the model that matches your existing AquaThruster cage: Sure-Flo Cage or Wire Cage.
The current Vortex Plate product description states that it is also compatible with Kasco's version of the shallow water installation kit.
It can. On a Dock Post Mount with 360 Oscillator, the Vortex Plate may reduce the available rotation area. Check clearance after installation.
No. The product is designed as a quick and easy shallow-water installation accessory for a compatible AquaThruster cage.
No. It is an accessory selected to match the existing Sure-Flo Cage or Wire Cage configuration.

AquaThruster
I wish I would have bought it years ago. No more hand raking and hauling away heavy weeds & trash that wash in to my dock area.

Vortex plate
Our 1hp Aqua Thruster is attached to our dock. In the middle of the night it sounded like a snowplow was going down bare roads. We finally saw the thruster creating a vortex when we heard the horrible noise, generally as the lake quieted down/smoothed out. The plate has worked to stop the vortex, thank goodness!
