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

    Aqua Thruster 360

    Posted by Randy B on 10th Apr 2021

    Unlike many of the other reviews, we didn’t need algae blown away from the surface of our dock. We have, or I should say had, a serious “muck” problem. We live off an inlet to the Ohio river and sediment flows down nearby Kentucky hills and is deposited in from of our dock. Combined that with decaying leaves, tree branches and dead fish, we had a serious much problem. We purchased a *XYZ Muck Blower* about two years ago and after the second gasket leaked and blew the GFI we had had enough and started searching for a better product. We stumbled across the Aqua Thruster but was hung up on the $2500 cost (3/4 HP with 360 oscillator). We had paid less for the ^XYZ blower*. After about 5 months of going back and forth, we finally took a leap of faith and purchased the AquaThruster about 2 weeks ago. I can completely confirm that in that two weeks we have moved about 2-2.5 feet of muck from underneath our boat lift. This was just enough muck removed to get our new 30’ boat onto the lift just last night- which we were ecstatic about. If you are on the fence about this product, spend the money. I can confirm it does move muck and, while I’ve only had it two weeks, it seems to be a much built much better and a more reliable product than our previous experience. (WeedersDigest has removed the competitive product name and replaced it with the *XYZ* brand in this review)

    Aqua Thruster

    This unit did in one day what all other attempts to clean my lake front couldn't do in months. Very happy and no chemicals. Awesome tool for a lakefront home owner.

    Money well spent

    Posted by Mike K on 3rd Oct 2020

    I use to rake for hours, moving muck, debris and floating weeds. In a few hours, this thing moved all the loose debris, muck and leaves away from our shoreline and dock. We have a nice sand bottom! We run it periodically just to keep surface gunk away. Wife loves beung able to get her kayak in without trudging through the muck. I love this thing!! One criticism, is the mount could be improved to remove the unit from the mount easier. And to have the ability to "spin" the unit to change direction easier. Yes you can losen the hex bolt then spin it, little inconvenient. All in all, very happy we bought this. Time and back saver.

    1hp Aquathruster 360

    Posted by Todd Jones on 28th Sep 2020

    After battling muck and weeds along my dock and shoreline for five years with a dredge, rake, aeration system, and muck pellets, I can honestly report that the Aquathruster 360 has done more to improve the quality of my waterfront in three weeks than all of my previous efforts combined. This machine is a godsend. Easy to set up and program, I have gained two feet of water depth around my dock in less than a month. It is not cheap, but it is very well built and produces a very strong current. As many others have reported, my neighbors are planning to purchase Aquathrusters of their own after seeing my results. This product is worth every penny for those struggling with muck and weeds along their dock and waterfront. Although expensive, the Aquathruster is money well spent, and will be recouped several times over by increased property value when we go to sell.

    Works quickly

    Posted by unknown on 1st Aug 2020

    We debated on getting this for a couple years but my husband finally gave in. After our lake front not being able to be remotely swimmable for 20 years after running it for 36 hours we could see the sandy bottom. I'm excited to out it in the spring to get a larger area.

    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
