Superior Fuel Efficiency

Best In Class 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 20% less fuel* than others in its class.


Multi-port Programmed Fuel Injection adds both easy starts and improved fuel efficiency - without sacrificing performance.

Tough Corrosion Resistance

Honda’s exclusive 4-Front Corrosion Protection System offers a patented, double-sealed multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.

Repositioned anodes and a new bolt coating boost corrosion resistance further.

A fresh water flushport flushes debris and saltwater out of the engine.

Legendary Reliability

True 5 Warranty: Unmatched peace of mind

Honda Quality

Our outboards share many technologies and components used in Honda vehicles, with all the benefits of years of proven Honda engineering, precision manufacturing and reliability.

Engine Alert System

The Engine Alert System monitors vital engine functions and prevents engine damage by alerting the operator of: overheating, water in fuel, low oil PSI, battery, over-rev, and critical engine function.

3-Way Cooling System

Three separate cooling systems keep the cylinder heads running cooler for long-term durability.

Simple, Effortless Control

Honda's exclusive Intelligent Shift and Throttle (iST) command and control system delivers superb control plus plug-and-play installation of Honda Marine products and third-party controls and devices.

iST offers multi-engine applications, with fine tuning of throttle settings at any speed, enhanced docking and slow speed control, and a simple, easy to understand user interface. Available on select BF115, 140, and 150 models.

For dual outboards, integration with Dometic’s Optimus 360 joystick steering system makes maneuvering so much easier. Dometic’s SeaWays keeps you headed in right direction and SeaStation’s virtual anchoring system keeps you positioned over wrecks in hundreds of feet of water.

Easy Ownership

Superior battery charging for more usable power

The charging system offers an impressive 55 total amps with 40 amps of charging power for plenty of accessories.

Simplified maintenance

The little things make a big difference. The BF115, 140, and 150 are designed to reduce maintenance time for routine tasks like oil and filter changes.

Fisherman Friendly Variable Speed Trolling

A variable speed trolling switch makes fishing easy and convenient. Simply push the toggle switch to adjust the trolling speed in 50 RPM increments from 650 RPM to 1000 RPM.

On-board connectivity

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