Honda 350hp iST Outboard | Intelligent Shift and Throttle, Electric Start, 25" Shaft | BF350AXDA

The BF350AXDA is a 350hp V8 four-stroke outboard motor, featuring ist control and electric. Designed with a 25" shaft and standard rotation, this engine is engineered for larger watercraft including offshore fishing boats, pontoon vessels, and performance cruisers requiring reliable high-output propulsion.

This outboard utilizes a V8 engine architecture with four-stroke operation, delivering smooth power delivery and improved fuel efficiency compared to two-stroke alternatives. The iST system provides precise throttle and shift control, while the standard propeller rotation ensures optimal torque distribution for the intended hull configuration. The 25" shaft length is appropriate for transom heights commonly found on larger recreational and commercial vessels.

Notable engineering features include Intelligent Shift and Throttle for smooth electronic control. The engine is constructed with marine-grade materials and finishes designed to withstand prolonged exposure to harsh marine conditions.

The 350 horsepower output rating provides substantial thrust for vessels in the mid-to-large size range, supporting activities such as offshore fishing, watersports towing, and extended cruising. The four-stroke design operates on standard unleaded fuel without requiring oil premixing, reducing operational complexity and exhaust emissions.

Engineered for durability and long-term reliability, this outboard incorporates advanced cooling systems, protective anodizing, and sealed electronic components. Standard equipment typically includes the outboard motor unit, propeller, control system components, and operator documentation. Installation requirements vary based on vessel configuration and should be performed by qualified marine technicians.

This product meets applicable marine engine emissions standards and is backed by a manufacturer warranty covering defects in materials and workmanship under normal use conditions.
