Honda BF350 HP Outboard Engine Key Features

• VTEC™ Technology: Originally developed for the iconic Honda NSX supercar, VTEC™ provides a superior combination of low-end torque and high-end power. It’s like having two engines in one—optimised for efficiency at cruising speeds and high performance when you need it.
• BLAST™ (Boosted Low Speed Torque): For those who want instant response, BLAST™ advances ignition timing during rapid acceleration, getting your hull up on plane faster than ever.
• ECOmo Fuel Economy: Honda’s Lean Burn Control technology automatically adjusts the air-fuel mixture according to speed and load, providing class-leading fuel efficiency during cruising.
• Intelligent Shift & Throttle (iST): Experience effortless control with this drive-by-wire system. It ensures smooth shifting and provides the foundation for advanced features like cruise control and automatic tilt/trim.
• AMP+ for Power On Demand: At idle, if the engine senses a heavy load from your onboard electronics, AMP+ automatically increases the RPM by 100 to boost charging capacity by an additional 12 Amps, keeping your batteries topped up while you're at anchor or trolling.
• Whisper-Quiet Operation: Designed with a fully balanced 30-degree offset crankshaft, the BF350 produces exceptionally low vibration and noise levels, allowing for easy conversation even at cruising speeds.
• Smart Maintenance & Protection: Featuring 24 internal anodes and a dedicated freshwater flush port, the BF350 is built to withstand the harshest saltwater environments. For added security, it also includes an immobiliser ignition system requiring a remote smart key.

Honda BF350 HP Outboard Engine FAQs

What is the warranty on a new Honda BF350 in the UK?

When you purchase your Honda BF350 from an authorised dealer like Morgan Marine, you benefit from Honda’s true 5-Year Warranty—a non-declining factory warranty that provides the same level of protection on the last day as it does on the first.

Does the BF350 require premium high-octane fuel?

No. Despite its high performance and V8 configuration, the BF350 is designed to run efficiently on standard unleaded petrol (91 RON or higher), helping to keep your running costs manageable.

What is 'AMP+' and how does it help me on the water?

AMP+ is a clever charging system that prevents battery drain. If you are idling and using high-draw electronics (like large GPS screens or live wells), the engine automatically increases its idle by 100 RPM to provide an extra 12 Amps of charging power.

Can I use a joystick with the BF350?

Yes. The BF350 is fully compatible with the iST (Intelligent Shift & Throttle) system, which allows for plug-and-play installation of joystick control systems (like the Optimus 360). This makes docking even the largest vessels a stress-free experience.

How does the Automatic Tilt feature work?

The BF350 features a "One-Motion" tilt. With a double-click of the tilt switch, the engine will automatically tilt to a full up or full down position, which is incredibly handy when you're arriving at a shallow mooring or packing up for the day.

Is the BF350 noisy?

Quite the opposite! Honda has engineered this V8 with a unique crankshaft design and superior insulation to ensure it is one of the quietest engines in its class. You’ll be able to hold a normal conversation at the helm even while at cruising speed.
