Honda BF350AUDA 350HP – iST 30″ Shaft Standard Rotation in Silver

Honda BF350AUDA 350HP V8 iST

The Honda BF350AUDA pairs a 5.0L V8 with standard rotation, built for deep-V center consoles that don’t need counter-rotation balance. At 782 lbs dry, this engine holds a strong power-to-weight ratio for sustained offshore performance. The 30-inch extra-long shaft delivers the reach and torque this platform is built for in Mulmarine’s marine outboard engines lineup.

Peak output runs across the 5000-6000 RPM range. The 1.79:1 gear ratio gives a hydrodynamic advantage, translating torque into quick hole-shot acceleration and efficient hull planing. Built with Honda’s usual Japanese engineering, this corrosion-resistant unit includes vibration dampening for a quieter ride during demanding saltwater runs.

Technical Specifications of Honda BF350AUDA

• The 5.0L V8 32-valve SOHC architecture delivers strong displacement for heavy-load acceleration.
• Standard right-hand rotation gives efficient hydrodynamic thrust for primary single-engine installs.
• iST enables precise drive-by-wire control for effortless shifting and throttle synchronization.
• A 93-Amp alternator delivers 70 net Amps of charging for marine electronics.
• Integrated electric power steering compatibility gives effortless helm control in rough offshore conditions.
• Programmed Fuel Injection manages precise combustion for reliable cold starts and thermal efficiency.

V8 VTEC Architecture

This V8 uses VTEC to shift cam profiles at high RPM, holding thermal efficiency and a flat torque curve for sustained power on long-range cruises.

PGM-FI Fuel System

The PGM-FI fuel induction system manages the air-fuel mixture precisely to optimize efficiency and reduce consumption, giving instant throttle response during high-speed transit.

Extra-Long Propulsion Shaft

The 30-inch extra-long shaft’s standard-rotation gearbox maximizes thrust and propeller grip while minimizing drag in heavy offshore swells, keeping tracking consistent on large fiberglass deep-V hulls.

Advanced Marine Electronics

NMEA 2000 certification lets this unit communicate directly with modern helm displays, while the 93-Amp alternator keeps high-draw radar suites fully powered.

Honda Factory Coverage

Honda Marine backs this unit with a 5-year limited warranty covering major components against manufacturing defects, with nationwide support for US owners.

Premium Cruiser Match

This silver V8 fits luxury center consoles and high-transom offshore cruisers that need heavy-duty thrust for coastal inlets and offshore swells.

Maintenance & Longevity

Routine inspection of the 5.0L V8 cooling system prevents internal salt corrosion and overheating; check the wet sump lubrication system regularly for peak protection. Pro Tip from the Shop: verify the integrated electric power steering harnesses are securely connected and free of moisture to prevent steering lag during high-speed offshore cruising.
