ENGINE FEATURES
|
World Famous Quality
By sharing many components with the Honda Accord, CRV and Element automobiles, the BF 150 and 135 gains years of proven Honda engineering and reliability. |
Dual Overhead CAM (DOHC)
A powerful, compact 24-valve DOHC design creates more valve lift to pull in more air for increased horsepower. Low-maintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed. |
VTEC
Variable Valve Timing & Lift Electronic Control system achieves the best of both worlds, by utilizing mild cam lobes to operate the intake valves at low RPM-then, at 4500 RPM, engaging a "high output" cam lobe for high RPM operation. |
Lean Burn Feedback Control
Utilizes a Linear Air-Fuel Sensor, along with the Engine Command Module, to automatically adjust the air-fuel mix according to speed and load - maximizing power throughout the RPM range and providing twenty percent greater fuel economy in the cruise mode from 2000 to 4500 RPM. |
3 Way Cooling System
Three separate cooling systems keep the cylinder head cooler for more long-term durability. |
51 AMP Alternator
Belt-driven to reduce heat and improve reliability, the BF150’s charging system delivers 20 Amps at idle, 30 Amps at 1000 RPM and a generous 40 Amps over 2000 RPM to ensure a constant charge and keep electronics going. |
Engine Command
The ECM receives constant input from 18 different sensors to deliver instant starts, smooth operation, strong performance and excellent fuel efficiency. |
Dual Stage Induction
A variable air intake manifold delivers top performance at every speed. At low speeds, air passes through a loing intake runner, increasing low-end torque. Above 3500 RPM, shutter valves open to shorten the air's path, boosting air flow for more high-end torque. |
LAF & Knock Sensors
Linear Air Fuel (LAF) and knock sensors help determine correct fuel flow and ignition curve to maximize performance and fuel efficiency. |
Engine Alert System
The ECM monitors vital engine functions and prevents engine damage by alerting the operator of:
- Overheating
- Water in Fuel
- Low Oil PSI
- Battery
- Over-Rev
- Critical Engine Function
|
Multi-port Programmed Fuel Injection (PGM-FI)
Delivers the precise amount of fuel/air to each cylinder. The result is quick starts, instant throttle response and low fuel consumption. |
Single Latch Cowl
A single front-mounted latch combines with 4 securing points to ensure a water-tight seal. |
Positive Lubrication
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components. |
Sealed Starter
The starter motor is inverted into a sealed chamber that protects the starter bendix drive from the elements. |
Non-Linear Mounting System
Patented non-linear rubber mounts provide smoother operation at all engine speeds. |
Corrosion Protection System
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection. |
Fresh Water Flushport
Flushes debris and saltwater out of the engine, extending the life of the outboard. |
Stainless Steel (Steering Arm, Tilt Tube and all Shafts)
Durability with long-term corrosion resistance! |
Counter Rotation
Improves efficiency, hull maneuverability and decreases driver fatigue. |
Built-In Pitot Tube
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation. |
Ultra Low 3 Star Carb Emissions
Cleanest technology available. |
