ENGINE FEATURES
|
World Famous Quality
By sharing many components with the Honda Accord automobile, the BF115 benefits from years of proven Honda engineering and reliability. |
Programmed Electronic Fuel Injection
4 Fuel Injectors and a Common High Flow Throttle body deliver the precise amount of fuel/air to each cylinder, resulting in instant throttle response with superior fuel efficiency. |
Torsion Dampener
Sometimes called a flywheel, the torsion dampener’s location near the base of the powerhead, lowers the center of gravity for improved handling and hull maneuverability. |
Top Mounted Electronics
Alternators, ignition system and other critical electrical components are mounted near the top of the powerhead, keeping them cool and dry for increased dependability. |
Largest Displacement Engine
At 137 cubic inches, the BF115 has the largest displacement in its category. The long-stroke design increases torque to deliver outstanding performance and efficiency. |
High Output Charging
Belt-driven to reduce heat and improve reliability, the BF115’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 running. |
Balanced Engine
Twin counter-rotating balancers cancel out internal engine vibrations, providing smooth operation throughout the entire RPM range. |
Engine Alert System
Uses visual, audio and RPM reduction circuits to alert the operator of overheating, low oil PSI and over-revving, preventing engine damage. |
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. |
Forced Air Ventilation
A unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. Reducing the operating temperature improves performance and long-term durability of electrical components. |
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. |
Engine Command System
Engine Command Module receives constant input from 18 sensors located throughout the engine, then determines the correct fuel flow and ignition curve, providing optimum performance. |
Fresh Water Flushport
Flushes debris and saltwater out of the engine, extending the life of the outboard. |
Easy Maintenance
Front-mounted oil filter and oil fillers simplify maintenance, while "screw-type" valve adjusters reduce maintenance costs. |
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
Environmentally friendly technology. |
