Evinrude H300WZCA 300HP – H.O. G2 25-Inch

Evinrude H300WZCA 300HP G2 Digital Control

The Evinrude H300WZCA 300HP G2 represents a high-output premium high-performance engineering, featuring a high-displacement 3.4L V6 74-degree architecture in a sleek digital configuration. This High Output (H.O.) model is specifically designed for high-transom multi-species hulls and performance bay boats requiring high-performance marine engines with an extra-long shaft. Its 25-inch shaft and E-TEC G2 technology are explicitly calibrated for neutralized torque and stable hydrodynamic tracking during heavy-load applications in both fresh and saltwater transits.

Operational peak performance is managed through the integrated i-Control system, offering digital shift and throttle across a wide 5400-6000 full-throttle RPM range. The specialized 1.85:1 gear ratio effectively translates the 3441cc V6 energy into immediate thrust for rapid hull planing without engine hesitation or cavitation. Boaters use this BRP-engineered G2 platform for its high-pressure 133-amp alternator and the efficiency of a direct-injection system that delivers fuel economy and torque.

Advanced 74° V6 Architecture

The H300WZCA utilizes a specialized 74-degree V6 block that is engineered without traditional iron cylinder sleeves to maximize heat transfer and reduce dry weight. This architecture allows the motor to be significantly lighter than comparable 300HP four-stroke engines, resulting in better vessel balance and improved fuel efficiency. You gain the mechanical advantage of a large displacement powerhead without the penalty of excessive transom weight on performance hulls.

25-Inch Extra-Long Shaft

The H300WZCA motor integrates a 25-inch extra-long shaft explicitly calibrated for specialized high-transom vessel dimensions found on modern bay boats and deep-V skiffs. This specific lower unit immersion prevents propeller aeration in following seas while maintaining a secure grip on the water surface during maneuvers. US offshore This can provide improved steering authority and stable tracking when navigating through heavy coastal chop or technical lake channels.

Intelligent Digital Controls

This 300HP outboard utilizes the ICON II digital shift and throttle system to provide a smooth and cable-free operating experience at the helm. This interface removes traditional mechanical cables to helps support precise vessel command during technical docking maneuvers and high-speed operation. You experience a higher level of control when navigating through busy marinas or technical waterways with the reliability of high-speed digital signal processing.

Super-High Displacement Performance

The 3441cc (210 cu in) V6 powerhead provides the foundation for torque and smoother power delivery than smaller displacement competitors. This balanced architecture reduces vibration throughout the vessel while providing the torque needed for rapid response under heavy tournament loads. Operators may notice a refined four-stroke-like quietness with the strong low-end punch of a high-performance direct-injection system at the transom.

High-Output Electrical System

The H300WZCA features a class-leading alternator system delivering a 133 amps of total output, with 50 amps net dedicated specifically to the electronics. This electrical capacity supports multiple large-screen navigation displays, high-draw sonar equipment, and stabilizing gyro systems without draining the starting battery. US This can provide the confidence to run complex digital networks and radar during extended offshore excursions or overnight coastal cruises.

Integrated Oil Management

The G2 series features an integrated 2.0-gallon internal oil reservoir, which eliminates the need for an external oil tank taking up valuable space in the boat’s bilge. This innovative design simplifies engine rigging and allows for up to 50 hours of operation before needing a refill, which can be done easily through the top of the cowling. This convenience is a game-changer for offshore cruisers who prioritize storage space and clean mechanical installations.

Factory Warranty and Service

This Digital V6 engine is built with high-quality sacrificial anodes and a quad-thermostat system to prevent destructive galvanic corrosion daily in saltwater. The H300WZCA is protected by a 3-year BRP Limited Warranty, ensuring long-term peace of mind and access to a global network of certified technicians.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
