Evinrude H300WZC 300HP H.O. G2 25″ Digital Outboard

The Evinrude H300WZC is a 300hp counter rotation outboard designed with a 25-inch 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 539 lbs to maximize rigidity. Crafted explicitly for deep-V sterns, the 25-inch shaft length 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.

Counter Rotation High Output Tuning

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.

Hydrodynamic SLX Gearcase Profile

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.

Twin Engine Transom Match

Twin-engine offshore fiberglass center consoles, multi-engine sportfishing platforms, and deep transom walkarounds ranging from 22 to 30 feet provide the appropriate match. Its 25-inch shaft prevents propeller ventilation when ascending 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.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
