The BF150 sets the standard in innovation with its advanced inline four-cylinder technology, placing this engine in a league of its own.
The BF150 features Variable Valve Timing and Lift Electronic Control (VTEC) initially developed for Honda's high-performance sportscars.Introduced in the early 1990s, VTEC is the benchmark technology used on every Honda motor vehicle sold today.The system ensures smooth, stable idling with an even further reduction in fuel consumption, while the increased valve lift at high revs broadens the torque curve and provides incredible top-end power.
Along with Honda's Programmed Fuel Injection, the BF150 incorporates Lean Burn Control technology, which allows combustion to operate on a leaner air/fuel ratio than stoichiometric air/fuel.An O2 sensor, together with the ECM, precisely controls the air/fuel mixture for the best fuel economy at cruise settings. The mode in which lean burn control is used during cruising to achieve higher fuel economy is referred to as ECOmo (Economy Controlled Motor).Pair this with the BF150's Multi-Port Programmed Fuel Injection (PGM-FI) that delivers the precise amount of air/fuel to each cylinder, and what do you get? Quick starts, instant throttle response and low fuel consumption.
All shafts, the Steering Arm and the Tilt Tube are made from stainless steel. Alongside the Freshwater Flushpoint that flushes debris and saltwater out of the engine, extending the life of the outboard, you've got durability with long-term corrosion resistance!The starter motor is inverted into a sealed chamber that protects the starter bendix drive from the elements.And a crankshaft-driven, automotive-style trichoid oil pump ensures the long-term durability of critical engine components.
The BF150's Linear Air Fuel and knock sensors help determine the correct fuel flow and ignition curve. They improve the overall engine operation and efficiency and prevent engine damage.The BF150 also benefits from the patented, 'double sealed' multi-layered paint process of its Corrosion Protection System. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.And three separate cooling systems keep the BF150's cylinder head cooler for more long-term durability.
