Working in performance boating is exciting: It’s fast-paced. Propulsion systems and hull designs are in continual evolution. Our customers are generally astute, technically oriented and often quite colorful characters. We’re all performance freaks! We’re all continually learning. That’s what makes my job so much fun!

If you are like me, your first boating experiences were in lower horsepower boats used primarily for family recreation, fishing, skiing, wakeboarding, or general cruising. And like me, your boating experiences and knowledge have evolved over time.

When working with high-end performance boats and experienced customers, one tends to assume people have basic product knowledge. However, a propeller is complicated. Because our backgrounds vary widely, our levels of understanding vary widely, too. So, we’ll revisit the basics and then dive deeper on propeller form, fit and function.

Back in the 1980s, Quicksilver Accessories published a book entitled, Everything You Need to Know About Propellers. It was a bible for folks like me who were learning about a very complicated and critical component that is used in diverse applications and environments. Much of the information I will be sharing is from the fifth edition of this knowledge guide.

The guide includes some interesting history on the development of propellers.

Prop Terminology.
Anyone who has shopped for a propeller has been exposed to terms describing the various design functions. I remember when props evolved from two to three blade designs. And when replacing the prop on the family runabout, all you needed to know was the diameter and pitch.

In the go-fast world of performance boating, diameter and pitch are important, but many other factors come into consideration as well. Its all about efficiency. Diameter, pitch, rake, cup, rotation, number of blades, blade thickness, blade contour, skew, ventilation, cavitation, elevation, and angle of attack all come into play when propping a boat for maximum performance and efficiency.

I’ll get deeper into these facets of propeller design that affect boat performance in my next post, Prop School – Part 2: Terminology.

👋hello Everyone! I’m new to the prop game and I’ve been chasing 70mph with my 2002 2200v  pathfinder with a “300r torque master 1.75.1” and the best I’ve seen so far is 62.8 at about 6050rpms with a solace scorpion “worked Yamaha T1” 

I have gone through the ringer with a bunch of props and this is the best one I’ve seen so far for top speed. I also was wondering if anybody could be able to point me in a better direction my knowledge is in wiring and not propping. So. Any help would be much appreciated. Thank you in advance..
