Evinrude C175GXCP 175HP G2 30″ Counter-Rotation Outboard

The Evinrude C175GXCP is a 175hp counter rotation outboard designed with a 30-inch ultra-long shaft for multi-engine offshore boats. This 2.7-liter V6 platform handles offshore high-seas operation by distributing its 2744 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 5000 to 6000 RPM threshold. The optimized 2.17:1 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.

Slate Gray V6 Block

Advanced 2-stroke engineering treats the cylinder configurations of this 66-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 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.

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 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 servicing right at the marina slips.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
