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

Honda BF350AUDA 350HP V8 iST

The Honda BF350AUDA is a flagship 350HP V8 iST outboard designed for high-performance offshore operations in the United States maritime market. Featuring a 5.0L displacement and a dry weight of 782 lbs, this engine provides an unparalleled power-to-weight ratio for sustained commercial performance. This 30-inch extra-long shaft model is ideally suited for deep-V center consoles requiring standard rotation. Our reliable marine outboard engines deliver the thrust necessary for navigating turbulent coastal waters. Operational peak performance for the Honda 350HP is achieved across the 5000 to 6000 RPM range. The 1.79:1 gear ratio offers a distinct hydrodynamic advantage, translating offshore torque into rapid hole-shot acceleration and efficient hull planing. Built with uncompromising Japanese engineering, this corrosion-resistant unit incorporates advanced vibration dampening to helps support a quiet, smooth ride during marine salt-water excursions across North American coastal environments.

Technical Specifications of Honda BF350AUDA

V8 VTEC Architecture

This V8 outboard utilizes VTEC technology to shift cam profiles at high operational RPMs. This mechanical transition helps support maximum thermal efficiency while maintaining a flat torque curve. It provides the sustained power that modern mariners demand for long-range cruising.

PGM-FI Fuel System

The Honda BF350AUDA fuel induction system precisely manages the air-fuel mixture to optimize efficiency and reduce overall consumption. This helps support instant throttle response and consistent power delivery during high-speed transit. It is specifically engineered for high-performance American saltwater sportfishing and boating.

Extra-Long Propulsion Shaft

The 30-inch extra-long shaft features a standard rotation gearbox that maximizes thrust and propeller grip. Its profile minimizes drag while maximizing efficiency in heavy offshore swells. This configuration helps support consistent tracking on large fiberglass deep-V hulls during oceanic missions.

Advanced Marine Electronics

NMEA 2000 certification allows this unit to communicate directly with modern helm displays. The 93 Amp alternator helps support high-draw radar suites remain fully powered. Captains can monitor fuel induction data in real-time for safer navigation in open waters.

Honda Factory Coverage

Honda Marine protects this Honda 350HP unit with a comprehensive 5-year limited warranty for American owners. This factory-backed coverage covers major components against manufacturing defects to helps support long-term reliability. It reflects a commitment to quality that professional mariners depend upon.

Premium Cruiser Match

This silver V8 outboard is the ideal match for luxury center consoles and high-transom offshore cruisers. It provides the heavy-duty thrust needed for navigating coastal inlets and heavy offshore swells. It remains a staple choice for US recreational boaters.

Maintenance & Longevity

Routine inspection of the Honda BF350AUDA 5.0L V8 cooling system is vital to prevent internal salt corrosion and overheating. Regularly inspect the wet sump lubrication system to helps support peak mechanical protection for all internal engine components.Pro Tip from the Shop:Always verify that the integrated electric power steering harnesses are securely connected and free of moisture to prevent any steering lag during high-speed offshore cruising.
