The Martec Mark III folding prop is the lowest drag version available. The simple, four part design means no gears to jam and no window needed to check blade position, no shaft lock and no un-feathering. Martec 2-Blade feathering props offer alternative low drag propulsion for heavier displacement boats, particularly hulls with a modified fin or full keel. Martec 3-Blade feathering props offer power and low drag for heavy cruising boats.
Gears are larger for added strength and reliability.
