BF115 Honda Marine Engine

INTRODUCTION

The Honda BF115 Large Outboard Motor is a big performer. Thanks to its Boosted Low Speed Torque (BLAST®), 3-Way Cooling System and having the largest displacement in its class, it has outstanding performance. Plus, its high output alternator gives you an exceptional level of amps and the NMEA 2000 protocol allows engine data to be connected with onboard systems. The convenient and easy-to-use technology found in the Honda BF115 iST®helps to deliver a noticeably smooth and controlled boating experience. Harnessing Drive By Wire (DBW) technology, a system that relies on electronic controls for shifting and throttle (whereas a mechanical system relies on cables for shift and throttle), the Honda BF115 iST®moves past the stiffness of traditional mechanical motors. The BF115 iST®does not come with a propeller. Please consult with your Honda Dealer for propeller application assistance.

Performance and Efficiency

4-Stroke design, based on the Honda Accord

Based on the Honda Accord engine platform, the BF115 benefits from years of proven Honda engineering and reliability.

Dual Overhead CAM (DOHC) – High horsepower, low maintenance

A powerful, compact 16-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.

BLAST^® System – improves acceleration at low speeds

Boosted Low Speed Torque, or BLAST, improves acceleration at low speeds. A quick movement of the throttle control activates the BLAST^® system, advancing the ignition curve aggressively. “Hole Shot” is vastly improved as more horsepower gets the hull up on plane quicker.

Multi-port Programmed Fuel Injection (PGM-FI) – Powerful performance

Programmed Fuel Injection delivers the precise amount of fuel/air to each cylinder. The result is easy starts and instant throttle response with superior fuel efficiency.

Lean Burn Control^® – Superior fuel efficiency

Lean Burn Control^® increases fuel efficiency by allowing combustion to operate on a leaner air/fuel mixture. At cruising speed, this engine runs on up to 19% less fuel* than its predecessor.
*Based on EPA Specific Fuel Consumption Mode.

Largest Displacement Engine in Its Class

At 144 cubic inches, the BF115 has 21% more displacement than any competitor in its class. The long-stroke design increases torque to deliver outstanding performance and efficiency.

Balanced Engine – smooth operation

Twin counter-rotating balancing shafts help minimize internal engine vibrations, thus providing smooth operation throughout the entire RPM range.

LAF & Knock Sensors – Optimum Efficency

Linear Air Fuel (LAF) and knock sensors help determine correct fuel flow and ignition curve to maximize performance and fuel efficiency.

Engine Command System – Optimum performance

The Engine Command Module receives constant input from 18 sensors located throughout the engine. It determines the correct fuel flow and ignition curve, providing optimum performance.

Reliability and Durability

3-Way Cooling System – Cool running durability

Three separate cooling systems keep the cylinder head running cooler for more power. A warmer block helps prevent oil dilution.

Engine Alert System – Keeps you informed

Uses visual, audio and RPM reduction circuits to alert the operator of overheating, low oil PSI, over-revving, water in fuel, battery condition, and critical engine functions.

4-Front Corrosion Protection System – Fights the elements

A patented, “Double Sealed” multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors and painted interior cooling passages, all enhance corrosion protection.

Fresh Water Flushport

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

Stainless Steel components (Steering Arm, Tilt Tube and all Shafts) – corrosion resistance

Stainless steel components provide durability with long-term corrosion resistance.

Ultra Low 3 Star CARB Emissions

Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board’s standards.

Convenience and Ease of Use

Meets NMEA 2000 standards – on-board connectivity

NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as sonar or GPS.

High Output Charging – More usable power

The system develops 55 total AMPS, which after self consumption, delivers 40 “charging” AMPS. 30 AMPS at 1000 RPM and 40 AMPS above 2000 RPM.

Variable Speed Trolling

Another great advantage for fisherman is the 115’s optional push-button variable speed trolling control. Simply push up or down in 50 RPM increments from 650 RPM to 900 RPM.

Easy Maintenance

An 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 Pitot Tube

Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
