3 Blade Q Series

The 3 blade Q series is one of Sensenich’s original medium width composite hunt style propeller for use on many high powered direct drive applications. It was one of the first composite Airboat blades to hit the market with a swept blade shape and integrated I-beam laminate construction. For many Airboat enthusiast, the Q series is a great replacement option for older Powershift propeller systems. The swept blade shape reduces noise and decreases metal leading edge wear. These blades can be used on all direct drive automotive/aircraft engines and on belt reduction units where a smaller diameter propeller is required. The 3 Blade Q Series was one of the most popular propellers found on Lycoming & Continental powered Airboats producing 290 – 400+ HP, but after the introduction of the 74NGQ series blade, the Q series sales tapered off. Today, many Q series blades are built mostly as replacements for customers that do not want to upgrade to a newer design or that have an older Powershift / Water Walker hub and just need a set of blades to get them back on the lake. The Q has great hunt style performance for great low end push and the I-beam helps to reduce blade weight for improved throttle response.  All Sensenich composite ground adjustable blades are manufactured using an internal pressure, closed mold system. Aerospace grade epoxy pre-impregnated composite materials are cured at an elevated temperature to give the optimum strength at the minimum weight. A co-cured stainless metal leading edge is bonded on flush with the airfoil. The Q series blade is only available for use in Legacy 3 ring style hubs.
