The Turbo Pontoon 1 (Small Hub). The Turbo PONTOON 1 series of 3-blade propellers answers the need for better performance in the outboard pontoon, deck boat, and utility boat segment. Good acceleration, increased efficiency, as well as maneuvering ability, tops the characteristics found in the Turbo Pontoon 1 line. Outstanding thrust and control on outboard-powered (twin-log) pontoon boats, deck boats, sailboats, and utility/work boats, for increased acceleration and maneuverability. Resistant to ventilation, particularly in turns and at high engine trim levels. Features increased trailing edge cup, lower rake, and a larger diameter than typical propellers. Excellent for use with 3 and 4-cylinder outboard applications with 3.5-gear cases where extra thrust, maneuverability, and control are needed. Ideal for many applications using Yamaha's F70 outboard.
