The 3-Bladed McCauley Propeller D3A34C401/90DFA is offered for your airplane in 5 choices of diameter (80 inches to 88 inches in diameter, 84 landplane and 88 floatplane maximum). The extra blade adds static thrust, which improves take-off acceleration and climb. A three-bladed prop lessens the vibration and noise levels in the airplane in a way most people find more comfortable.
