Mercury 300CXXL — SeaPro
The Mercury SeaPro range is Mercury’s commercial-grade range built for heavy-duty, high-hour operation with extra durability for charter, hire and working boats. The 300CXXL uses Mercury Marine’s advanced fuel and ignition management for precise fuel metering at every RPM, giving outstanding fuel economy, easy cold starting and clean emissions that comply with Australian and New Zealand marine and waterway regulations. From Tasmania’s cold winter mornings to Queensland’s tropical heat, the 300CXXL starts reliably and delivers smooth, consistent power from idle to wide-open throttle.
Mercury 300CXXL — Extra-Extra-Long (30″) Shaft
The Extra-Extra-Long (30″) shaft on the 300CXXL suits boats with high transoms around 30 inches. Shaft length is one of the most critical specifications when choosing an outboard motor — selecting the wrong shaft length leads to propeller ventilation, poor performance and unnecessary wear. The 30″ shaft positions the propeller at the optimal depth for large centre consoles, hardtops and offshore cruisers, minimising cavitation and maximising thrust efficiency in real-world Australian and New Zealand operating conditions.
Mercury 300CXXL — Remote Control
The 300CXXL is configured with remote control — standard helm steering with throttle and gear shift at the helm station. This control configuration is matched to the vessel types and operating environments the 300CXXL is designed for, giving operators precise, responsive and comfortable control whether running open water, navigating estuary channels or working a favourite fishing spot.
Mercury 300CXXL — Black Cowling | Counter-Rotation
The 300CXXL is finished in black cowling — a clean, durable Mercury finish that suits a wide range of hulls. The lower unit is counter-rotating, designed for the port side of twin-engine installations. For twin-engine boat owners, pairing a standard-rotation motor on the starboard side with a counter-rotating motor on the port side eliminates propeller torque effect, delivering superior straight-line tracking, improved fuel economy and more precise handling — particularly at speed.
