Honda BF115

Honda Marine's 115 horsepower BF115 marine outboard engine benefits from decades of proven engineering from the world's largest engine maker.

Programmed electronic fuel injection delivers the precise air-fuel mixture for easy starts, instant throttle response, and outstanding fuel efficiency. And power is what it's all about-its 137 cubic inch displacement is the largest of any engine in its horsepower range.

A sophisticated engine alert system lets you see, hear, and feel a warning for overheating, low oil pressure, over-rev, battery condition, water-in-fuel, and critical engine functions. By sharing many components with the Honda Accord, the 115 HP, 4-stroke BF115 offers years of proven Honda engineering, precision manufacturing and reliability.

World Famous Quality
By sharing many components with the Honda Accord automobile, the BF115 and BF130 gain 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.

The result is easy starts, instant throttle response with superior fuel efficiency.

Torsion Dampener
Sometimes called a flywheel, it is located near the base of the powerhead. This design lowers the center of gravity for improved handling and hull maneuverability.

Improves handling and hull maneuverability.

Top Mounted Electronics
Alternators, ignition and other critical electrical components mounted near the top of the powerhead to stay cool and dry.


Largest Displacement Engine
At 137 cubic inches, the 115HP and 130HP have the largest displacement in those horsepower categories. The long-stroke design increases the torque output and offers the best in overall performance and efficiency.

High Output Charging
Belt-driven to reduce heat and improve reliability. The proven system delivers 20 Amps at idle, 30 Amps at 1000 RPM and a generous 40 Amps over 2000 RPM to ensure the batteries remain charged.

Balanced Engine
The 115HP and 130HP have twin counter-rotating balancers, which 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 critical engine component long-term durability.

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
Unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. The ventilation system reduces under-the-hood operating temperature, improving performance and long-term durability of the 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.

Fresh Water Flushport
Flushes debris and saltwater out of the engine, extending the life of the outboard.

Easy Maintenance
Easy "screw-type" valve adjuster system requires no shims and reduces maintenance costs. Front-mounted oil filter and oil filler make for easy maintenance.

Built-In Pilot Tube
Built-in pilot 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.
