Evinrude H300WXI 300HP G2 30″ iSteer DPS Outboard

The Evinrude H300WXI is a 300hp standard rotation outboard designed with a 30-inch ultra-long shaft for multi-engine offshore boats. This 3.4-liter V6 platform handles offshore high-seas operation by distributing its 3441 cc displacement over an optimized dry weight of 558 lbs to maximize rigidity. Crafted explicitly for deep-V sterns, the 30-inch ultra-long shaft helps support complete propeller immersion and continuous bite across large catamarans and offshore walkarounds navigating open ocean waters.

Sustaining high-speed cruising across offshore tournament distances is easy when running this heavy-duty powerhead within its 5400 to 6000 RPM threshold. The optimized 1.85:1 gear ratio translates internal combustion pressures into a sweeping torque curve to lift wide hulls on plane rapidly. Backed by proven USA engineering excellence, the propulsion platform provides mechanical consistency for captains operating far beyond standard coastal cell phone service ranges.

Technical Specifications of Evinrude H300WXI

- E-TEC direct injection pushes gasoline precisely for complete combustion and clean power delivery across the entire powerband.
- A robust 133-amp total alternator easily satisfies the heavy electricity demands of modern multi-display helms.
- Factory integrated iSteer dynamic power steering removes traditional complex plumbing with instant digital response at the wheel.
- The i-Trim automatic system makes trimming easy with a built-in automatic adjustment loop for shallow waters.
- An extensive 11.4-liter on-engine internal tank helps support components stay thoroughly lubricated during long wide-open throttle runs.
- The specialized lower unit gearcase helps support optimized hydrodynamic flow and efficient standard clockwise propeller thrust.

Classic White Premium Block

Advanced 2-stroke engineering treats the cylinder configurations of this 74-degree V6 block to optimize overall thermal efficiency. This build path cuts unnecessary pounds from the powerhead block while drastically accelerating thermal dissipation under severe high-load operations.

Stratified Fuel Induction Setup

Direct fuel injection pushes fuel straight into the heart of each cylinder for complete combustion cycles on 87 octane fuel. This automated network produces crisp throttle recovery and instant starting capability when navigating treacherous inlets or heavy head seas.

Hydrodynamic SLX Lower Unit

Oversized drive gears housed inside a heavy-duty lower unit minimize underwater drag profiles during high-speed cruising maneuvers. This robust engineering dampens heavy gear-shift vibration while maximizing directional tracking on deep-transom multi-engine fiberglass hull configurations.

Integrated dynamic Power Steering

Integrated dynamic power steering configurations combine directly with the digital controls to handle intensive tracking arrays automatically on open water. This digital platform coordinates with a high-capacity net charging setup to supply constant power to critical open-water electronics arrays.

Premium Multi Engine Integration

Premium multi-engine offshore fishing hulls, clean-rigging luxury pontoons, catamarans, and heavy express configurations ranging from 25 to 34 feet provide the appropriate match. Its 30-inch shaft prevents propeller ventilation when ascending rollers in rough open-ocean swells.

On Engine Reservoir Servicing

Unimpeded maintenance access is guaranteed by a sleek cowling array that detaches smoothly for immediate fluid evaluation. Slick drainage pathways isolate waste fluids to allow for quick oil changes right at the marina slips.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
