Honda BF150
The 2.4L, in-line 4-cylinder BF150 engine boasts Variable Valve Timing and Electronic Lift Control (VTEC™) Technology; Honda's exclusive Lean Burn Control and Three Way Cooling Systems; Dual Overhead Camshaft (DOHC) Technology and the exclusive Dual Stage Induction System. Derived from racing and first appearing on the Acura NSX sports car, VTEC™ utilizes mild cam lobes to operate the intake valves at low rpm, then engages a high-output lobe for high-rpm operation. Honda's exclusive Lean Burn Control maximizes fuel efficiency by automatically adjusting the air/fuel mix according to speed and load, while a top-mounted oxygen (O2) sensor works with the engine command system to deliver maximum fuel economy under any conditions. To ensure long term durability, Honda engineers designed the first individually-controlled cylinder cooling system for outboard engines. Three Way Cooling reduces engine heat by allowing the cylinder head to run slightly cooler than the cylinder block, greatly reducing engine wear. Dual Overhead Camshaft (DOHC) Technology creates added valve lift and greater air flow for higher horsepower. The roller/rocker arms generate less friction and wear, resulting in longer engine life. Unlike traditional DOHC designs, Honda valves are easy to adjust and contain no complex bucket shims. An exclusive Dual Stage Induction System uses a plenum chamber with twin butterfly valves for low speed drivability and high-speed performance. At low speeds, air passes through a long intake runner for increased low-end torque. At more than 3,500 rpm, shutter valves open to shorten the air's path, boosting air flow for higher horsepower. While other 4-stroke engines use long intake manifolds to deliver air to the cylinder head, the Honda design maximizes combustion efficiency. Finally, the BF150 features a 2.14:1 gear ratio; a belt-driven 51-amp alternator that offers the best charging in its class; an engine oil cooler; stainless steel components and a patented 4-Front Corrosion Protection System to create an extremely reliable and rugged power plant. Honda BF135 Similar to the BF150, the powerful, compact, 2.4 litre Honda BF135 boasts Lean Burn Control and Three-Way Cooling Systems; Dual Overhead Camshaft (DOHC) Technology and Dual Stage Induction to make it unbeatable in its class. Like its 150hp sibling, the BF135 engine uses Multi-Port Programmed Fuel Injection to deliver a precise amount of air/fuel to each cylinder under all operating speeds and conditions. This translates to quick starts, instant throttle response, powerful performance and low fuel consumption. Honda Marine pioneered 4-stroke engine technology, setting a new benchmark for fuel efficiency, quiet operation, and low emissions. Honda's outboards share the same unparalleled durability, quality, and reliability of its legendary automobiles.
