What does that mean for you? Quite a lot, actually. With a dual overhead camshaft, the compact, 2.4-liter, DOHC design creates more valve lift to pull more air for increased horsepower. The BF150 features Honda's exclusive VTEC system, which was previously offered only on the BF225. This advanced technology delivers more power, torque and efficiency at every speed. The sequential, programmed electronic fuel injection (PGM-FI®) delivers the precise amount of fuel and air to each cylinder, resulting in instant throttle response with superior fuel efficiency and like all Honda outboards, the BF150 is environmentally friendly.
