The Industry leader in preventing ice damage for over 40 years!

Industrial strength, energy efficient and cost effective! When a Kasco De-Icers motor is submersed it pushes water to create a flow of warm, bottom water using an open propeller design. This moves the warmer water to the surface to create open water areas. The industrial strength design of this dock de-icer has a single open propeller which allows for greater water flow. The coated stainless steel cage/propeller guard also catches large debris and reduces the likelihood of clogging.

Kasco De-icers come complete for suspended operation from a dock or boat in either a vertical or angle position - it can be hung with the provided ropes or purchase a universal dock mount, or horizontal float mount to produce an elongated pattern of agitated water while a vertical position produces a circular pattern.

Each De-Icer boasts the following staples of Kasco equipment:
  • Longer-life top and bottom ball bearings
  • Comes with two 20' braided nylon mooring lines attached
  • Environmentally friendly oil-filled motor with a hard-face internal mechanical seal and external lip seal for protection against leaks.
  • Flood oil lubricated for excellent heat dissipation.
  • Highly efficient, lower power consumption than competitive equipment
  • Superior dependability in salt-water or other corrosive environments. All external metal motor, float, and hardware components are of stainless steel composition and protected by a sacrificial zinc anode.
  • Requires minimal maintenance. We recommend cleaning the stainless steel motor housing once or twice per year and replacing the sacrificial zinc anode when visibly corroded.
  • Extremely efficient and productive operation generating excellent flow per kW of power used
  • ETL listed to stringent UL and CSA Safety Standards
  • Made with pride in the U.S.A.
  • 2 year warranty

Video Transcript

[Narrator] Today’s Kasco de-icers are the results of over 40 years of experience in the design and manufacture of superior water agitator equipment. Their main use is the prevention of damaging ice in marinas and harbors or for wet storage of boats in the winter. They can also be used to prevent oxygen related winter kills, attract water fowl in winter and improve the water quality during the summer in stagnant areas.

Kasco de-icers work simply by moving warm bottom water that is heated by the earth to the surface. De-icers can be mounted by rope suspension, a universal dock or piling mount or by a horizontal float. They are different type of ice damage to protect against. One of the most common is ice jacking or lifting of pilings. Lifting damage can occur anytime ice and water fluctuate. The most common cause of lifting is the tide however lifting damage is common in the Great Lakes region where the weather and wind changes can cause smaller but more rapid changes than tides.

Jacking damage can also occur on any body of water regulated by man. Repair costs are not only limited to physical damage but also the downtime of dock facilities and time spent obtaining necessary government permits. Maintaining an ice free zone in and around dock structures is your very best protection against jacking or lifting damage.

[Speaker2] Here on the Wisconsin River below the Weyerhaeuser Dam. I put my dock in the last summer. Put the nice heavy-duty dock in thinking I wouldn’t have a lot of trouble with ice. It turned out to the river kind of chewed it up and spit some polls right out at me. So I called up Kasco Marine and told them my situation, and they came up with some ideas for me.

Okay I used the dock mount. All I’ve done is adjust it mildly around to keep the ice going, it has worked very well. And what they did to work absolutely fabulous. It took the ice out, within two weeks it was completely gone. It looks like it’s going to work very well.

[Narrator] Ice expansion pressure is a vastly underrated damage risk. The size of a body of water is directly proportional to the risk potential. The larger the body of water the larger the potential damage risk will be. Although maybe prefer to maintain and ice free zone around the dock structure it is also possible to limit damage risk with an open water buffer zone. Kasco de-icers placed correctly between docs and expanding ice can relieve damaging expansion pressure.

During harsh winters with thick ice and heavy snowpack your pond can experience a fish die off or Winterkill due to low oxygen levels. The heavy snow and ice prevents sunlight from penetrating into the water causing the existing aquatic vegetation to die off. As the visitation die, the decomposition process uses up much of the available oxygen in the pond. Only a small percentage of the ponds total surface area needs to be ice free to prevent winterkill situations. The cold water will become oxygenated by coming in contact with the air and prevent winterkill on your pond.

Water quality during hot summer weather is an increasing problem for marinas and waterfront developments. Sheltered water behind docks or under walkways where wind and current cannot reach tends to become stagnant and dirty. As a result algae and odor problems often develop destroying and otherwise pleasant outdoor experience. The use of Kasco de-icers during hot summer weather to create a man-made current helps mother nature with her natural cleaning action for improved water quality.

Back in the late 80s, Kasco sent our de-icing equipment and company personnel 312 miles north of the Arctic Circle to help with the whale rescue off the coast of Barrow Alaska. Although Kasco Marine had no official invitation we were convinced our equipment could do the job. So Kasco decided to crash the party. At first local officials did not take Kasco’s de-icing equipment seriously but they quickly became enthusiastic after seeing the great results Kasco delivered. There was also a friendly reception from the whales. Kasco’s 3/4 horse power de-icer on a horizontal float help maintain ice free breathing holes for the trapped whales at temperatures consistently reaching -30°F.

So we’ve seen how Kasco deicers can be used for multiple applications. Kasco is the industry leader in ice control engineering. These energy savers are the standard from the people that know de-icing.

[Mazzola] The Chicago Police Marine unit, Sergeant Mazzola , this is officer Bill Brown. And you can see in the background we have our water-movers working and we’ve had these for approximately six years. We haven’t had any problems and this year Officer Brown put them in all by himself. Bill you could go ahead and tell us what happened there.

[Bill] We carry about 25 - 26 in water when the whole system is fully operational. It keeps a nice ice shelf all the way around the perimeter of the boats. So we are able to move the boats. We have to bring the boats to the wall in order to fuel them during the winter so we can take the boats out and keep us operational all year round. It’s been a very reliable system that we have going here. It keeps us functioning and I don’t know what we would do without them.

by Donald from St Louis, Missouri on January 02, 2012
Upon installation i always verify operation by bypassing t-stat. Deicer did not start. I pulled from water and spun blade thru several times then dropped back in water and tried again. This time it started. Restarted several times and all apears well. Cant help but think if i may have a problem later in season. I will say deicer moves considerable amount of water to keep my dock clear and is built solid. There was no mention of my experience as stated above in the operating booklet so my reason for a score of 4. Thanks

My 4th Kasco De-Icer, I purchased 1 a couple years back for my dock in Canada, and have purchased 3 since for neighbors on the lake who had "cheaper" units, and returned in the spring to find their docks and ice eaters gone with the thaw. you can even drill a hole in frozen over area's put these in and the ice will be gone in a few days ....amazing product.

What HP is needed for small 10 ft deep lakefront in Indiana with E shaped dock and large 25 ft. pontoon lift?
3/4 HP covers up to 75 feet diameter. That's what you will need to know. Only 1-2% of the total surface area needs to remain ice free to prevent the devastation.
De icer was on while out of water because tide was pushed out. does not run now. can motor be repaired?
