Optimal Propellers with Custom Rakes from Milwaukee Casting Foundry
What is the Rake of a Propeller?
The rake of a propeller is the degree of which the blades are perpendicular to the hub. The average degree for an outboard propeller is within 15-20 degrees, but the angle can vary, depending on the specific application.
There are different types of propeller blade rakes, including:
- Positive – propeller blade is positioned away from the hub
- Negative – propeller blade is positioned towards the hub
- Progressive – the angle of the propeller blade increases as it gets closer to the hub
- Flat – the angle of the propeller blade is the same throughout
- High- increases speed
- Low – reduces drag
R2 Quality Castings is Wisconsin’s custom propeller manufacturer that creates one-of-a-kind components for virtually any industry. We utilize our craftsmanship and experienced technique to benefit the propeller’s performance, which also advances the entire industry. Searching for a propeller with a custom blade rake? We’ll take care of you.
The Higher the Rake, the Better the Performance
High rake, or higher-angled propellers come with several benefits. High rake propellers attached to boats help the vessel move much faster and more efficiently. Whether you need propellers for aeration, construction, or a water treatment facility, Quality Castings can manufacture custom components for a variety of industries.
Advantages of choosing high rake propellers include:
- Helps boats mobilize through aerated water, which bonds to the propeller blades better
- Increases thrust & controls the water better, because of the high rake pushing out more water
- Holds boats higher on the water, which creates less drag & increases speed
Keeping it Steady: Benefits of Low Rake Propellers
A low rake, or low-angled propeller is a better option for lightweight boats. Vessels that don’t weigh as much already have some speed, but with a low rake propeller, the boat will experience less drag and more powerful movement.
Quality Castings provides both high and low rake propellers. We don’t do simple “cut-and-dried” propellers for each order. Every propeller is hand-crafted from one of our metal casting professionals and verified for trusted quality. Aside from marine propellers, we also cast food mixers, construction equipment components, custom artwork, and more!
