Airboat Propellers
Small airboats are just plain lots of fun! The Ultra-Prop is a popular choice with bow fishing and Flounder enthusiasts. It’s also tough and impervious to water, and therefore ideal for this application.

“Last autumn, I purchased the 66-inch 3-blade Ultra-Prop II. I remember my delight on that first flight with the new propeller… how smooth it was, and much more noticeable thrust! I’ve now flown 500 hours with the Ultra-Prop II and I continue to have the feeling that I’m flying a new airplane.”
