Introducing Ultra-Prop II
We are now shipping the Ultra-Prop II with a newly designed blade having optimum twist and fabricated with a new engineering thermoplastic resin with carbon fiber reinforcement.
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.
