Evinrude H300GXC 300HP G2 30″ Digital Control Outboard

Description

The Evinrude H300GXC is a 300hp counter rotation outboard designed with a 30-inch ultra-long shaft for multi-engine offshore boats. This 3.4-liter V6 platform handles extreme high-seas operation by distributing its massive 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 ensures complete propeller immersion and continuous bite across large catamarans and offshore walkarounds navigating open ocean waters.

Sustaining high-speed cruising across extreme 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 massive 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 absolute mechanical consistency for captains operating far beyond standard coastal cell phone service ranges.

Technical Specifications of Evinrude H300GXC

• 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.
• Integrated hydraulic steering with counter-rotation digital control rigging removes traditional external plumbing to streamline the transom layout.
• 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 ensures components stay thoroughly lubricated during long wide-open throttle runs.
• The counter-rotation lower unit ensures reversed propeller spin for balanced tracking on dual or quad engine configurations.

Slate Gray Counter Rotation Block

Advanced 2-stroke engineering treats the cylinder configurations of this 74-degree V6 block to optimize overall thermal efficiency. This advanced 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 Hydraulic Steering Control

Integrated hydraulic 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.

Twin Engine Transom Match

Twin-engine offshore center consoles, heavy deep-transom catamarans, offshore walkarounds, and coastal commercial transoms ranging from 24 to 32 feet provide the perfect match. Its 30-inch shaft prevents propeller ventilation when ascending massive rollers in rough open-ocean swells.

Internal Tank Fluid Management

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 servicing right at the marina slips. Pro Tip from the Shop: Flush the integrated hydraulic steering valve block located within the stern assembly during annual maintenance to keep your digital counter-rotation tracking response crisp and lag-free.
