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

Q: Do I need to select the same power cord length option for both the Aqua Thruster 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 Aqua Thruster with 360 Oscillator?
A: The 1 HP Aqua Thruster 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 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

    Thruster, oscillator and bottom frame

    Posted by Sharon on 2nd Sep 2021

    We LOVE this thruster!! I tell people it’s the best money I ever spent. We’ve been raking out weeds for 50 years and now we have just a tiny bit. It’s wonderful - I get excited every time I look at the beach - no weeds and the water is clear. We bought the bottom frame because we wanted to be able to move it since we have a large frontage. It’s expensive but worth it. Our backs appreciate it - ha.

    Aqua Thruster

    Posted by Chris on 27th Jul 2021

    Very happy with the results that we are having with the Aqua Thruster. We have seen a great amount of improvement in eliminating the lake weed away from the swim platform. We have had to check on the fan every day and clean the weeds from it and rake the weed debris from around the swim platform. We are loving getting in and swimming again without the weeds brushing up around our legs. I would highly recommend this product!

    Posted by Matt S on 18th Jul 2021

    I should not have waited as long as I did to purchase the Aqua Thruster. It has totally transformed the area around my dock and lift. We have a swimmable beach again!

    AquaThruster 3/4 HP with dock mount.

    Posted by Nancy S on 20th Apr 2021

    This is an amazing tool that has solved a big problem for me. I live on a seepage lake and struggle dearly with lake levels when we don’t get much rain. Last summer I used a pressure washer to sink my boatlift as the level went down. It worked fine and I was able to use my boat all summer. The problem came when it was time to get the lift out in the Fall and not pretty. Now I can easily move muck/silt in no time. The only mistake I made was to not order the oscillator. I have now and will use it to maintain depth around my pier and boatlift.

    3/4 hp Aqua Thruster and 360

    Posted by Dan M on 20th Apr 2021

    I have the 3/4 hp Aqua Thruster 360. Amazing is all I can say. After only 2 revolutions the bottom went from 18” of water with muck 2-3 feet deep to being able to see sand and pebbles at least 30 feet in all directions. We’ve also gained over 2 feet of water depth. Waiting for warmer water to see how the bottom is to walk on, we’ve not been able to enter the water previously in the area by the dock. If your thinking about this product, just buy it, it works!

    Best Thing Ever

    Posted by Travis He on 15th Apr 2021

    This thing is amazing!!! We had at least 3ft or more of muck. I ran this for a month straight, along my shoreline going back and forth and in and out as far as the 50ft cable could go while using the Lake Bottom Frame. I now have sand!!! A few improvements would be great however. 1) adding to the oscillation a z-wave remote app to remote control from a smartphone or tablet. I am big into home automation and use SmartThings to remote manage a lot of things at my cottage 2) upgrade the timer to be Z-wave as well to remote control the on/off schedule. I bought a GoControl WO15EWZ5-1 GFCI smart outlet and ran power to my shoreline. I can now control the on/off schedule and remote turn it off/on remotely at will. The outlet is like $45. You do need a home automation hub like SmartThings. 3) add a top mount stabilization bar to the free stand with the 360 oscillation add on. I have the 1hp thruster and man that thing has torque. It twists the oscillation pole as it rotated on the free standing mounting pole. I made my own out of 1 1/2 galvanized pipe. You need two T’s that are 1 1/2, two reducers to 3/4, and one 8 inch long 3/4 pipe. Then by a tap set and drill one hole in each T and screw in a set screw so the rig stays in place. It cost a total of $25 with all the parts listed above.
