Yamaha Z300BETOL Specification

The Yamaha Z300BETOL is a high-performance outboard motor engineered for reliability and efficiency, ideal for both recreational boating and commercial applications. It features a four-stroke, in-line four-cylinder engine with a displacement of 2.8 liters, offering optimal power and fuel efficiency. The engine is equipped with Yamaha's advanced electronic fuel injection system, ensuring precise fuel delivery for improved throttle response and reduced fuel consumption. This outboard motor is designed with a 20-inch shaft length, making it suitable for various boat types.

The Z300BETOL is built with Yamaha's Shift Dampener System (SDS) which minimizes the noise and vibration typically associated with shifting gears, providing a smoother and quieter operation. The engine also incorporates a double overhead camshaft (DOHC) design, enhancing performance by allowing for more efficient airflow and combustion. Its lightweight and compact design do not compromise on power output, delivering a robust 300 horsepower.

Durability is enhanced with Yamaha’s anti-corrosion protection, using a combination of a proprietary alloy and a five-layer paint process to prevent corrosion and extend the engine's lifespan. The outboard motor also includes a variable trolling RPM switch, allowing for better low-speed control, which is particularly beneficial for fishing activities. Engine monitoring is facilitated through a digital network gauge, providing real-time data on performance metrics such as RPM, fuel flow, and engine temperature. The Yamaha Z300BETOL is an embodiment of advanced marine technology, offering a blend of power, efficiency, and reliability for a superior on-water experience.
