Kasco Marine

<h3>About Kasco Marine</h3><p>Few brands can claim they invented an entire product category, but Kasco Marine can. <strong>Founded in 1968</strong> when a Minnesota marina operator engineered one of the world&apos;s first de-icers, the company set out to solve a simple but costly problem: protecting boats and docks from the destructive force of freezing water. That single innovation launched a brand that has spent more than five decades defining the standard for aquatic water quality solutions worldwide.</p><p>Headquartered in Prescott, Wisconsin, Kasco Marine operates out of a family-owned facility with over 60,000 square feet of engineering, manufacturing, and warehouse space. That in-house capability means tight quality control and fast delivery — two pillars of a reputation built over generations. Today, Kasco distributes its products through a network spanning more than 30 countries, and its lineup has grown far beyond its de-icing roots to include aerating fountains, surface and diffused aeration systems, circulators, and beneficial bacteria biologics.</p><h3>A Legacy Built on Water Movement</h3><p>The core engineering principle behind nearly every Kasco product is the same: move water strategically to improve its quality, prevent damage, and support aquatic life. In the mid-1980s, Kasco engineers adapted the reliable de-icer motor design to create pond and lake aerators — products quickly adopted by fisheries and aquaculture operations. A further refinement added a pumping chamber to produce Kasco&apos;s iconic aerating fountains, which combine visual appeal with genuine water quality benefits.</p><p>Whether the application is a residential backyard pond, a busy marina, a municipal retention basin, or a commercial fish farm, Kasco products are engineered for continuous-duty performance in demanding environments. Stainless steel construction, dielectric oil lubrication, heavy-duty seals, and corrosion-resistant components all contribute to the brand&apos;s reputation for durability and low maintenance.</p><h3>Kasco Marine Products for Marinas &amp; Waterfronts</h3><p>For boat owners and marina operators, two Kasco categories stand out as essential cold-weather and year-round investments. The brand&apos;s industry-leading <a href="/7412-kasco-marine-de-icers-200302">De-Icers</a> remain the go-to solution for preventing ice damage at docks, pilings, and boat slips, while a range of <a href="/200325-dock-accessories-kasco-marine-7412">Dock Accessories</a> — including universal and industrial dock mounts — make installation and positioning of those units straightforward for any waterfront setup.</p><p>Kasco de-icers are available in 1/2, 3/4, and 1 HP configurations and are ETL-approved to stringent UL and CSA standards, making them among the most rigorously certified units on the market. Optional thermostat control panels allow the units to activate only when temperatures demand it, keeping operating costs in check throughout the winter season. Every unit ships with two 20-foot mooring ropes for immediate suspended operation right out of the box.</p><p>Pair a de-icer with Kasco&apos;s stainless steel and composite dock mounting hardware and you gain full control over unit depth, angle, and direction — critical factors in maximizing the open-water zone around valuable watercraft and structures. It&apos;s a complete, field-proven system backed by the brand that started it all.</p>

Product Details

The Kasco Marine 3400D025 De-Icer is a high-performance water agitator designed to prevent ice formation around boats, docks, piers, and other waterfront property. The powerful 3/4 HP motor creates large amounts of water flow that prevents ice formation and protects property from damages of ice jacking and ice expansion pressure. A single 3400D unit is capable of maintaining an open circle of water up to 75 feet in diameter.

Key Features:

  • 3/4 HP motor with 120V operation, producing 36 lbs of thrust and drawing 6.6 amps
  • Features longer-life top and bottom ball bearings, highly efficient low power consumption, and flood oil lubrication for excellent heat dissipation
  • Corrosion-resistant stainless steel construction makes this unit ideal for use in salt water or other corrosive environments
  • Includes two 20-foot hollow braided suspension ropes and a replaceable sacrificial zinc anode
  • Built-in thermal overload protection and 25-foot water and oil-resistant power cable
  • Stainless steel safety cage offers protection from the pitched performance propellers
  • ETL approved to CSA and UL standards
  • Continuous duty operation rated for year-round use

Performance and Benefits:

The de-icer allows oxygen to enter the water in winter, providing improved water quality and habitat and helping avoid devastating winterkill of fish. The unit can be suspended vertically or at an angle using the included mooring ropes, creating either circular or oblong ice-free openings. During summer months, the de-icer can be used to circulate water, improving water quality and helping to eliminate stagnant and dirty water.

What's Included:

  • Kasco 3400D de-icer unit with stainless steel safety cage
  • 25-foot SJTOW underwater-rated power cord
  • Two 20-foot suspension ropes
  • Replaceable sacrificial zinc anode

Optional mounting accessories including universal dock mounts, industrial mounts, and horizontal floats are available separately. Thermostat and timer controllers are also available to help save power and improve de-icer performance. For best performance, position the unit 4-6 feet below the water surface and always keep at least 1 foot above the bottom.
