Stainless Steel vs Aluminum Boat Props | What’s the Difference Between Stainless and Aluminum Props

So what’s the difference between stainless and aluminum boat props?

In this video from Boats.net, John will guide you through the pros and cons of aluminum props and stainless props. In a nutshell, the biggest difference between aluminum and stainless steel props can be found in the strength and rigidity of the material. On a smaller boat, with less horsepower, an aluminum prop will work fine. Its light weight is a nice fit for the lower power of the engine.

But on a larger boat, with more horsepower that can literally bend the blades of an aluminum prop and change the pitch, you want the benefits of a steel prop. It cuts through the water with lower drag and won’t flex under the power of a bigger outboard.

The aluminum prop is cheaper, and if cost is a consideration it’s hard to beat. On the other hand, you may be looking for the crisp power transfer to the water that comes with a stainless steel prop.
