Michigan Wheel Marine produces various lines of outboard propellers, each with its own distinct characteristics and applications. The Ballistic Propeller, for instance, is designed for those who need explosive speeds and reliable performance in aggressive environments. It is made of premium quality materials that have been selected for their superior properties. Deep Blue Yacht Supply is the industry leader when it comes to supplying Michigan Wheel Ballistic stainless steel propellers, order your Ballistic propeller today. Material Composition Michigan Wheel chose to create this propeller with 15-5PH stainless steel using one-piece investment cast construction. This grade is known for being resistant to corrosion so it is perfect for marine applications. It is also strong enough to withstand high pressure which can be present when the boat is running at full speed. A number of heat treatments may be employed to strengthen the material prior to fabrication. This alloy is made up of chromium, nickel, and copper. There may also be trace amounts of silicon, sulfur, manganese, phosphorous, and carbon. Meanwhile, the hub it coated on the inside with a durable rubber for shock absorption. Design The Ballistic propeller has a Power Tip design that is known to enhance power efficiency. This tip curvature, along with the blade cup, improves the prop's bite in the water for reduced slippage. They also minimize the physical damage and power losses brought about by the effects of cavitation. The leading edge has been tapered to lower drag without sacrificing blade integrity. A lot of models have interchangeable hub systems but the design team has opted to use basic hub geometry in this case to simplify installation and repair. Ballistic props have a pressed in hub, so you do not need the XHS Hub Kit with this propeller.
