  • Can be used with or without the 360 Oscillator
  • The Aqua Thruster can easily be removed from the mount for easy storing.

  • Can be used with or without the 360 Oscillator
  • Easy to move from post to post as needed!

Q: What are the power requirements for a 1 HP Aqua Thruster with 360 Oscillator?
A: The 1 HP Aqua Thruster with 360 Oscillator requires 110V power, and has an amp draw of 12.5 Amps. We also offer a 220V version of the 1 HP Aqua Thruster.

Q: Do you have mounting options available if I don’t want to put my Aqua Thruster on a dock?
A: Yes! We have a free standing frame that’s compatible with our Aqua Thruster 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 Aqua Thruster is programmable from 0-359 degrees.

Q: Should I run the Aqua Thruster 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 Aqua Thruster. Many users will operate their Aqua Thruster 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 Aqua Thruster?
A: Your Aqua Thruster 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 Aqua Thruster. 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 Aqua Thruster 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

    The Aqua Thruster Is All It Is Cracked Up To Be!

    Posted by Steve Radowski on 30th Jul 2020

    We are in Day Two of using the Aqua Thruster and our experience mimics all the reviews we had read previously. We can't believe that we will actually be able to have a swimming area for our grandkids after looking at muck for years. In just over 14 hours, we are seeing firm sand for the first time. It has been a joy to watch the transformation, and we look forward to years of muck-free swimming and lake pleasure. We would absolutely recommend the Aqua Thruster to anyone who questions whether their situation is beyond help!

    Aqua Thruster works as advertised

    Posted by Bob on 27th Jul 2020

    We bought the 3/4 hp, and it is working just as we hoped. Years of muck & weeds being pushed away. Had we got this in the Spring before the weeds took root I think it Would have been even more effective, but we can see bottom sand and rock again.

    Aqua Thruster with 360 oscillator

    Posted by Kerry Adams on 10th Jul 2020

    We'll engineered and robust construction. Ease of programming the oscillator is a plus. A single pole with the pole mount isn't quite enough to support so I installed 3 into the lake bed with triangular support arms. It works well installed that way. Very sturdy. 4 instead of 5 stars is for the short cords. My house is 32' exactly from the wall where the plug is to the seawall. The Thruster is 3' out from the seawall and I had to add extension cords. Not a big issue. So far using 180 degree sweep has cleared over 120' of shoreline. My neighbors (we have small 50' frontage lots) are thrilled!! They are considering going in together and getting an Aqua Thruster. Thank you from a retired mechanical design engineer for a well designed and very functional product. Kerry Adams

    Aqua Thruster

    Posted by Paul Renard on 27th Aug 2019

    It’s nothing short of a miracle. I purchased the 3/4 hp with oscillator a SDSU stand. Took a while to get the right settings in terms of the angle that I set it at. As some other reviewers have indicated If it is set pointing too deep it will move the bottom and create a whole. If set too shallow it doesn’t do as good of a job. It takes a little experimenting, but it is absolutely amazing. Don’t hesitate to buy this. Worth every penny +++++

    UNBELIEVABLE System!!!!!

    Posted by Russ Scribner on 27th Aug 2019

    If I didn't see it with my own eyes I wouldn't have believed it. We purchased our lake cottage four years ago & assumed we would have to live with the weeds & muck. I measured the muck at 2' to 4' in-depth around the pier. After two rotations we could see the bottom of the lake. As we made our way down the pier we have approx 100' of clear water & we couldn't happier than now the grandkids & kids can dive off of the pier. I also bought the stand as I have 500" of frontage & looking forward to results in the beach area & the rest of the shoreline.
