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.
