In a world premiere Honda has revealed its refreshed large-size outboard engines. The Honda BF250, BF225 and BF200 V6 and BF150, BF135, BF115 inline four (L4), at the Miami International Boat Show 2025, (that took place Feb. 12-16, 2025) in Miami, Florida, U.S.A.
All models unveiled will incorporate changes and modifications designed to improve durability, comfort, economy, styling, ease of use, and easier maintenance.
Honda L4 and V6 models, available with either Honda Intelligent Shift and Throttle® (iST®) drive-by-wire or mechanical control systems, feature a sleek, new exterior that follows the form and function of the innovative, award-winning Honda BF350 V8.
Designed for Enhanced Performance and Easy Operation
Honda Marine has updated a significant number of features on its high horsepower models to improve engine performance and make operation easy and intuitive. Honda L4 and V6 engines with Honda (iST®) drive-by-wire controls feature designs that are ergonomic, functional, user-friendly and tactile for stress-free operation. iST® is a plug and play system that does not require programming on single engine applications or special tools to install. With a compact, under the cowl design for as many as four engine installations, and a stylish, modern binnacle control box, iST® delivers near effortless shifting under all conditions.
- At the helm, new controls include a side-mount iST® 5-button, multi-function panel and single-lever neutral lock with a highly visible neutral indicator.
- The engines are compatible with the newest generation of 7-inch HD operating displays that provide better visibility and features as compared to current HD-4-and HD-5 displays.
- Drive-by-wire models are updated to include the same iST®-controlled automatic tilt, trim support and cruise control features found on the flagship BF350 V8.
- Three-engine applications now include a center engine control with a dual-lever iST® binnacle or third-party joystick control. The Optimus 360 by Dometic® Joystick is compatible with Honda Marine multi-engine applications equipped with iST®.
- Honda BF200, BF225, and BF250 V6 iST® engines feature large, easy-to-use levers and handles that are integrated into the engine design.
Inside the engine, additional updates and enhancements include:
- An optimised combustion chamber shape helps maximise efficient combustion and ensures consistent engine performance.
- A re-engineered and stronger starter motor mount and more rigid starter motor seal work to deliver consistent starting performance at the turn of the key.
- Improvements to the Honda-exclusive Lean Burn Control System help increase fuel efficiency across a wider range of conditions. A redesigned mid-section and a carefully placed O2 (oxygen) sensor help to achieve lower operating costs and increased time on the water.
Several additional Honda exclusives complete the newly enhanced Honda L4 and V6 model lineup. The models include Boosted Low Speed Torque (BLAST™) that advances the ignition curve for dramatically improved holeshot performance; Variable Valve Timing & Electronic Control (VTEC®) that provides smooth power delivery throughout the engine’s operating range, delivering more power with increased fuel efficiency; and Programmed Fuel Injection (PGM-FI) that provides quick starts, instant throttle response, powerful performance, and low fuel consumption.
Upgraded Components for Greater Durability and Reliability
Honda Marine outboards have earned a reputation for durability and reliability. Upgrades to L4 and V6 engine components make Honda engines even more resilient in demanding marine operating conditions:
- New oil pump and cylinder head gasket shapes provide better water drainage to help prevent corrosion.
- Improvements to fasteners and gaskets increase under-cowling corrosion resistance.
- New, extended valve adjustment intervals and iridium spark plugs increase the time between maintenance visits, giving boaters more time on the water.
- New, high-level fit and finish and high-rigidity parts on levers and handles help deliver years of durable protection against the elements.
Installation and Maintenance Made Faster and Easier
Easier engine installation and maintenance updates help boaters get the most out of Honda high-power outboards, adding up to less time at the dock and more time on the water while also making it quicker and easier to repower a boat with a new Honda engine:
- A repositioned transom bolt hole leads to ideal engine placement on the transom, reducing installation labour and testing time.
- A new oil filter position and new oil bypass work together to prevent messy drips and leaks while they speed and simplify oil changes.
- An updated vapor separator fastener makes for easier disassembly during maintenance.
Honda Marine L4 and V6 outboards, with their sleek new designs, will be available in the signature Honda Marine colours of Aquamarine Silver and Grand Prix White.
