Q: Do I need to select the same power cord length option for both the AquaThruster Motor and the Oscillating Attachment?  Do they use the same, or separate cords?
A: They DO NOT use the same power cord. It is up to you which cord lengths to choose for each. The Oscillator cord does not have to be the same length as the AquaThruster.

Q: What are the power requirements for a 1 HP AquaThruster with 360 Oscillator?
A: The 1 HP AquaThruster with 360 Oscillator requires 110V power (but they each have their own power cord) and has an amp draw of 12.5 Amps. We also offer a 220V version of the 1 HP AquaThruster.

Q: Do you have mounting options available if I don’t want to put my AquaThruster on a dock?
A: Yes! We have a free standing frame that’s compatible with our AquaThruster motor, and if you want to utilize the 360 Oscillator, check out our 360 Bottom Frame Mount

Q: How powerful are the AquaThruster motors, really?
A: People are surprised by how powerful the motors are. Make sure to mount the system securely.

Q: At which angle should the thruster motor be pointed?
A: Slightly pointed up. This helps so that you do not dredge the lake bottom.

Q: Can I change the rotation timing and speed of the Oscillator?
A: Yes the AquaThruster is programmable from 0-359 degrees.

Q: Should I run the AquaThruster constantly, or should I limit the hours it runs each day.
A: Each lakefront owner’s situation is different, and the circumstances will dictate the hours you should operate your AquaThruster. Many users will operate their AquaThruster around the clock for a couple weeks, then reduce operating hours to a few hours each day.

Q: Should I point it out to deep water or towards shore?
A: You can do both depending on what you are using it for. Please call a sales representative for additional operational advice.

Q: How deep should I have the thruster motor?
A: At least 2-3’ of water depth, ideally 4’.

Q: How deep does it reach?
A: The pole goes down to 5’ water depth, but you can reach deeper by adjusting the angle of the motor.

Q: What size post will it fit?
A: The portable post mount bracket fits round, square, and rectangle posts up to 4” diameter.

Q: How quickly will I see results?
A: The AquaThruster will demonstrate its effectiveness on surface stagnation in minutes. Even when clearing water that has been washed into your shore, the results are shockingly fast.

Q: What time(s) of year can I use my AquaThruster?
A: Your AquaThruster can be used starting in the spring, and through the fall to the point where temperatures get close to freezing. Early season use oftentimes results in less weeds popping up in your area, and later season use helps prevent decomposing vegetation from forming a muck layer in your area. In addition, summer use helps to keep boat chop debris, algae, and duckweed from populating on your shoreline.

Q: How can I move it from one location to another quickly?
A: Our Portable Post Mount or Freestanding mounting options make it very quick and easy to relocate the AquaThruster. The Standard Dock Mount is the only mount that is more difficult to quickly move around because it needs to be bolted to your dock surface. We recommend purchasing an additional mount or two, plus our Quick Mount, if you need to move it around. The Quick Mount will allow you the flexibility of quickly releasing your unit from mount to mount in less than a minute.

Q: Can the AquaThruster help my specific needs and how do I know what size motor to purchase?
A: If you are unclear of what size and mounting are best for your specific needs contact us and we will assist you with the best configuration for your needs. Choosing the right size AquaThruster motor depends on what you're trying to accomplish, how large of an area you want clear, and how much muck, sludge, leaves or debris you have on the bottom of your lakefront. Our website contains a diagram which will give you a general idea of how the thrust power differs between each HP motor options.

Q: Can I attach it to a seawall?
A: Yes, please contact a sales representative for additional guidance.

Q: Is it portable with remote frame?
A: Yes. We offer freestanding mounting options allowing you to position wherever you like.

Q: Do I need to replace the prop?
A: Only if it breaks

Q: Do I need a GFI?
A: A GFCI is always advisable.

Q: Made in the USA?
A: Yes made in the USA.

Q: Can it be used while swimmers are present?
A: No we do not recommend using while swimmers are present.

Q: Isn’t it dangerous to operate an electric motor in the water?
A: Yes! The AquaThruster blower motors are tested by ETL to meet stringent UL and CSA standards for underwater use.

Q: What is the chain for?
A: The chain enables you to attach the power cord to the protective cage

    1HP Unit is a Beast

    Posted by Brian Jones on 19th Oct 2023

    This is a well-made unit and the 1HP throws off significant force and turbulence to dislodge muck. Be careful because the unit can also dredge a deep hole in the bottom if pointed down.

    Aqua thruster exceeded our expectations!

    Posted by Donna Jordan on 30th Jul 2023

    We did not get the unit installed until mid July. At this point, the weed growth was well established. We did not expect much, but we're pleasantly surprised! Blew out muck and weeds galore! We will definitely be adding the oscillating unit for next spring! Not only did eradicate weeds where it was directed, we added several feet to our depth around the dock!

    Purchased my Aquathruster in 2017 and it is still going strong. We would have sold our cottage without it. And 4 of my neighbors bought one as well after seeing the results I was having. I would recommend this 100%. It is worth every penny.

    What an amazing product!!! High quality and powerful. Easy to set up and Charlie at Weeders Digest was extremely help. This was a long awaited Christmas present after years of raking and wheelbarrowing leaves and muck from our shoreline.

    Should Have Bought this years ago!

    Posted by Unknown on 14th Sep 2021

    Within a day of set up - I could see the bottom of my lake! Don't think I had ever seen it before. Biggest thing will be to use it to remove the silt before the weeds begin to grow next spring. Overall an a great product.! We were so happy with our purchase we bought more mounting options to give us flexibility. Thank you !

Choosing the right size AquaThruster blower motor depends on what you're trying to accomplish, how large of an area you want to clear, and how much muck, sludge, weeds, leaves, and debris you have on the surface and bottom of your lakefront.


All models except the 2 hp models come with the clog-resistant Sure-Flo Technology Aquaticlear Cage. A masterpiece of engineering to prevent debris buildup.


If you have questions or would like assistance regarding horsepower options, give us a call, start a chat, or send us a message. Once we understand your shoreline and current situation, we'll be able to suggest the most effective options for you.



The Dock Plate Mount connects to both the top and side of your dock using bolts. It's a great choice if you don't need to move it often.

 • Ideal for wood & aluminum docks and people who are able to drill holes in the decking and side of their dock. 
 • The AquaThruster can easily be removed from the mount for easy storage.
 • Can be used with or without the 360 Oscillator



The Dock Post Mount is a great option for docks that have posts that come up past the dock surface. It can quickly be mounted and relocated as needed to another dock post which helps maximize coverage area. 

 • Easy to move from post to post as needed!
 • Fits square and round dock posts up to 4" wide.

This is a great option if you don't have a dock, you want to set up your AquaThruster away from your dock, or you're not planning on purchasing the 360 Oscillator. With this choice, you can cover more ground by simply moving it along the shoreline as needed.
