This engine, part of the Mariner brand owned by Mercury Marine, features a powerful 20-horsepower, 2-cylinder 4-stroke engine paired with a jet drive system. This unique combination provides exceptional performance and versatility, particularly in shallow water conditions where traditional propellers might encounter difficulties.
