                            Mercury’s jet-drive outboards are specifically designed to pilot boats in shallow waters where propeller-driven hulls are unable to operate. Because there is no lower unit extending below the hull, the jet drive permits passage over obstacles that would foul a propeller-driven outboard boat. |
