PREMIUM POWER
HONDA’S FIRST V8
Honda’s first ever production V8 engine is designed to deliver maximum power with impressive fuel efficiency.
HIGHEST MAXIMUM POWER FOR EXHILERATING RIDES
Stunning speed and rapid acceleration provide exciting high propulsion operation, with smooth response and exceptionally robust torque.
POWER WHERE AND WHEN YOU NEED IT
Honda’s exclusive VTEC technology offers a superior combination of power, torque, and fuel economy.
INSTANT ACCELERATION
Honda’s exclusive BLAST system improves acceleration at low speeds. The result? Instant acceleration and improved hole shot.
FULLY BALANCED 30° OFFSET CRANKSHAFT
Every BF350 crankshaft is built using the same crankshaft alloy and tested to the same strength specifications as Acura’s famed NSX high-performance sports supercar. The fully balanced, 30° offset crankshaft eliminates the need for counter balancing; it seamlessly integrates with 60° engine design and nonlinear engine mount to provide exceptional performance with minimal vibration.
SUPERIOR FUEL EFFICIENCY
IMPRESSIVE FUEL EFFICIENCY
Optimized fuel efficiency extends range and reduces operating costs, outperforming the competition’s fuel efficiency at cruise by 17% and cost by 20%.
RUNS ON 86 OCTANE FUEL
The BF350 is a premium performer that runs on regular gas. That’s good for your wallet!
LEAN BURN CONTROL
Honda’s exclusive Lean Burn Control technology optimizes fuel efficiency by supporting effective combustion on a leaner air-to-fuel mixture.
RIDE FURTHER, LONGER
Less frequent need for refueling means more time enjoying boating.
PGM-FI
Multi-port Programmed Fuel Injection adds both easy starts and improved fuel efficiency – without sacrificing performance.
POWERFUL PERFORMANCE
TRIM SUPPORT
Trim support operates automatically based on engine or boat speed. Presets can be fine-tuned to adapt to changing conditions.
AUTOMATIC TILT
Automatic tilt offers easy, button-controlled, up-or-down tilt when stored or mooring with just two button presses.
CRUISE CONTROL
Cruise control allows boaters to maintain their preferred cruising speed or RPM for tow sports, while trolling for fish, or even while taking tight turns or boating in rough water.
HIGH THRUST CAPABILITY
High thrust capability provides superior maneuvarability and control, aiding in the positioning and stopping of large boats.
HIGH OUTPUT CHARGING FOR MORE USABLE POWER
High charging performance offers large power generation capacity of maximum 70A – exceeding the needs of typical on-board devices.
SAVE YOUR BATTERY WITH AMP+
At idle, when the engine senses a need for additional amperage, AMP+ automatically increases the rpm’s by 100 to produce an additional 9 amps. This helps prevent the draining of critical battery power when using multiple accessories.
EXTRAORDINARY EXPERIENCES
EXCEPTIONALLY QUIET
Quiet operation, even at cruising speed, for relaxed onboard conversations and enjoyable social experiences.
LOW VIBRATION FOR COMFORTABLE RIDES
Low-vibration design reduces vibration in the cruise zone for more comfortable boating.

Its single-line silhouette adapts to various hull shapes and environments, creating premium appearance that enhances any watercraft. Available in Aquamarine Silver or Grand Prix White, with chrome badging and black trim.
ON-BOARD CONNECTIVITY
NMEA 2000 protocols allow engine data to be interfaced with on-board systems and systems displays, such as SONAR or GPS.
INTELLIGENT SHIFT & THROTTLE
IST: SUPERB CONTROL
Honda’s exclusive iST® (Intelligent Shift and Throttle®) drive-by-wire system ensures superb, effortless shift and throttle control, plus plug-and-play installation of the Optimus 360 by Dometic® joystick system.

TOUGH CORROSION RESISTANCE
CORROSION RESISTANCE
Critical interior components use a high corrosion resistant aluminum alloy, resulting in a more durable engine and gear case.
EASY ACCESS ANODES
Easy access anodes make replacement quick and simple, for improved durability in salt water.
HI-M COATING
Bolts and brackets are treated with a special HI-M coating for superior surface finishing and corrosion resistance.
4-FRONT CORROSION PROTECTION SYSTEM
Honda’s exclusive 4-Front Corrosion Protection System offers a patented, double-sealed multi-layered paint process.
FRESH WATER FLUSHPORT
A fresh water flushport flushes debris and saltwater out of the engine.
LEGENDARY RELIABILITY
UNMATCHED PEACE OF MIND
