Yamaha F300ECB2 300HP White V6 Offshore 25″ Outboard Motor

Yamaha 300HP F300ECB2 White V6 Offshore 25in

The Yamaha 300HP F300ECB2 is a flagship 4.2L V6 outboard featuring a 25-inch shaft in a premium Pearlescent White finish. As part of the refined Offshore series, this 4166cc model utilizes a 24-valve DOHC design and Plasma Fusion cylinder walls to achieve a superior power-to-weight ratio and enhanced thermal efficiency. The mechanical soul of the F300ECB2 is built for versatility, compatible with Digital Electronic Control (DEC) to provide smooth, precise shifting and throttle response for high-end coastal cruisers and technical sportfishing skiffs requiring a traditional steering setup.

Achieving peak operational value, the F300ECB2 utilizes Multi-Point Precision EFI and Variable Camshaft Timing (VCT) to optimize torque output across the power band. The motor is protected by specialized anti-corrosion treatments and Yamaha’s proprietary Phaze Five paint system to defend against oxidation in high-salinity zones. Maintenance is simplified through the easy-access oil filters and a front-mounted freshwater flush port. This unit includes a stable 50-amp alternator, providing the necessary energy reserves to support modern navigational displays, fish finders, and essential shipboard accessory loads.
