FourStroke Jet Outboards

FourStroke Jet Outboards

Mercury® Jet Outboards are designed with the power and the weight to cover any shallow-water jet boat application. Our FourStroke jet outboards are electronic fuel injected, with a range from 25 to 80 horsepower.

Navigate Shallow Water

Navigate Shallow Water

Mercury® Jet Outboards are specifically designed to pilot boats in shallow waters where propeller-driven hulls are unable to operate. Because there's no lower unit extending below the hull, the jet drive permits passage over obstacles that would restrict access to a propeller-driven outboard boat.
