The answer is simple. Our de-icers / bubblers use maintenance free stainless steel, water cooled, and water lubricated continuous duty motors. Many of our competitors use an oil filled aluminum motor requiring expensive regular maintenance.
Competitor propellers typically are flexible nylon that break easily, while ours use a proprietary composite that has been impact tested with a steel bar while running without any failure.
Arbrux boat de-icers / bubblers also have a protective structure around the propeller to prevent power cable damage while allowing leaves and other small debris to pass through. Arbrux boat de-icers / bubblers come with a motor mount made of welded stainless steel for increased strength and durability.
