The propeller made of stainless steel have less rotating mass than other materials, which equates to faster acceleration. The blades are much thinner than aluminum and brass materials. The thinner blades are able to slice into the water much more effectively than others. It is much more effective propeller that drives to boat through the water with less power than the other materials. The stainless steel propeller blades are also machined with a much better-designed cup in the blade. The cupping of the blade allows the propeller to hold more water on the blade`s surface with high performance.
Advantages:
1, high performance
2, fuel economy
3, smoother ride
