A good prop is necessary for proper boat propulsion. Props can dramatically effect top end speed, bow lift, and planing time.
Dings, wear and bent blades can also adversely effect the boats performance.
The most common materials used for props are aluminum, stainless steel, brass and plastic composites. In high performance boats, stainless steel is often chosen due to it's strength. Reduced cross sectional area of the blades in stainless steel props is possible because of the alloys strength. This reduction reduces slip and increases efficiency.
I just spent the morning talking with fourth and fifth grade boys enrolled in the "Boys on the Move" program at Alamo Elementary School near my home. It's the school my sons and I attended.
Many a word has been spouted (and often with a good degree of accuracy) with regard to practice and how important it is for improvement. And, as with most old sayings, they ring true.
