Mercury 30MHGA 30HP Gas Assist Manual 20″ Outboard Motor

Mercury 30HP 30MHGA Gas Assist Long Power

Technology focused and utilizing a 500cc three-cylinder engine family, the Mercury 30HP 30MHGA serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 30HP four-stroke technology utilizes a Gas Assist cylinder to maximize mechanical efficiency during tilting, effectively converting internal combustion into efficient thrust for high-transom utilities and fishing boats. The 20-inch long shaft design provides an optimized center of gravity, while the manual recoil with battery-free EFI ensures immediate, one-pull ignition across diverse inland and coastal environments.

Operational longevity of the 30MHGA model is secured through a specialized pressurized lubrication system featuring a high-capacity oil sump to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a vapor-free fuel induction system that eliminates the need for a battery, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and an ergonomic carry handle, this fuel-efficient outboard provides superior ownership value for boaters seeking a lightweight, low-emission engine with manual simplicity and assist-tilt functionality.
