The propeller is manufactured from 319 marine-grade aluminum alloy for strength and corrosion resistance. It uses a through-hub exhaust design and comes with a Flo-Torq II hub system for easy installation. The 14H433 propeller is ideal for bass, fishing, and pontoon boats operating at mid-range rpms. Its 3-blade design provides good acceleration, top speed, and fuel economy.
