Choices for Aluminum Propellers
Two very common metals used for casting boat propellers are stainless steel and aluminum, with aluminum being the most commonly used metal for this purpose. Boating enthusiasts are divided in their opinion of the two, with some strongly preferring aluminum props over any other kind. One major advantage of aluminum propellers is their affordability; boaters can often buy them for a fraction of what a stainless steel propeller in the same size range would cost. Aluminum propellers are also highly portable, in part because the nature of aluminum makes them lightweight. In addition, these propellers deliver high performance and are appropriate for a wide range of boating activities.
One caveat about aluminum props, however, is that they must be kept painted in order to keep corrosion at bay.
Michigan Wheel Aluminum Propellers
The Michigan Wheel company, a historically well-respected name in propeller manufacture, offers many different models of aluminum prop. They produce two major lines of such propellers: the Vortex and Michigan Match series.
Vortex propellers from Michigan Wheel feature XHS hub technology and incorporate features such as geometric blades that deliver high performance in part because they are precisely balanced for maximum efficiency in the water. They also look attractive, boasting a powder coat finish that will help to prevent corrosion from forming on the blades or hub. All Vortex props come with a limited lifetime warranty.
Michigan Match propellers feature a hub already pressed in, which means there is no need to purchase an additional hub kit. Michigan Match propellers are manufactured from high-level aluminum alloys that help the prop stay in excellent condition for many years.
