Yamaha F300XCB 300HP DEC Digital V6 25″ Outboard Motor

Yamaha 300HP F300XCB DEC Digital V6 25in

The Yamaha 300HP F300XCB is a technologically advanced 4.2L V6 outboard featuring a 25-inch shaft and full compatibility with Digital Electronic Control (DEC). As part of the modern Offshore series, this 4166cc model utilizes a 24-valve DOHC design and Plasma Fusion cylinder walls to achieve peak performance while maintaining a lightweight profile. The mechanical soul of the F300XCB is defined by its smooth, digital shifting and precise throttle response, offering the operator a level of vessel control that is essential for both technical sportfishing and high-speed coastal cruising.

Focused on superior operational durability, the F300XCB features Multi-Point Precision EFI and Variable Camshaft Timing (VCT) to ensure reliable starting and optimal torque density across all RPM ranges. The chassis is shielded by specialized anodic protection and Yamaha’s proprietary Phaze Five anti-corrosion system to mitigate galvanic wear in high-salinity marine environments. Routine maintenance is simplified by the front-mounted freshwater flush port and easy-access top-mount oil filter. This unit includes a stable 50-amp alternator, providing the necessary energy reserves to support modern navigational displays, sound systems, and shipboard accessory loads.
