Honda Outboards has been producing Four Stroke outboards for over 50 years and even produced the first Four Stroke in 1964. Their engines are based off their extremely reliable car engines, including the Acura RL, Accord, and Fit. They are the only outboard company to make an air-cooled 2.3, allowing for maximum weight savings and low maintenance. These engines can rack up the hours and keep running, clean as can be. Their transferable 5-year warranty assures you that the engines are solid and will treat you and your boat well.
