Evinrude K115HGXF 115HP – H.O. E-TEC G2 iSteer DPS 25-Inch

Evinrude K115HGXF 115HP H.O. iSteer DPS

The Evinrude K115HGXF 115HP H.O. G2 is a revolutionary 25-inch extra-long shaft outboard featuring a high-displacement 1.9L inline 3-cylinder engine architecture with fully integrated iSteer digital steering. This High Output (H.O.) model is specifically engineered for high-transom bay boats and technical skiffs requiring advanced high-output marine engines with an power-to-weight ratio. Its Integrated Dynamic Power Steering (iSteer DPS) provides the surgical precision and lightweight agility needed for navigating unpredictable coastal environments or running narrow technical channels with complete helm authority.

Operational efficiency is maximized through a high-displacement powerhead that delivers low-end torque, managed by the i-Control digital shift and throttle system across a 5000-6000 RPM range. The K115HGXF utilizes a specialized 2.00:1 gear ratio to translate the 114 cubic inch displacement into immediate hydrodynamic thrust for rapid hull planing without mechanical lag. US tournament boaters depend on this 3-cylinder G2 platform for its fuel atomization and the industry-first clean rigging that consolidates steering, shift, and throttle into a single tube.

High-Displacement 1868cc Inline-3

The K115HGXF utilizes a 1.9-liter block to provide significantly higher torque and smoother power delivery than standard 115HP four-stroke competitors. This G2 mechanical design helps support strong hole-shot acceleration, pushing technical hulls onto plane instantly even when fully loaded with gear and fuel. Operators may notice a refined and quiet operation that maintains the strong low-end punch essential for technical shallow-water and offshore fishing.

Integrated iSteer Dynamic Power Steering

This G2 outboard features iSteer Integrated Dynamic Power Steering (DPS), which builds the steering actuation directly into the engine midsection, eliminating all external hydraulic lines. This digital steering provides adjustable feedback and precision for the captain, resulting in an incredibly clean transom and high-speed tracking. This can provide a higher level of control and reliability through the total elimination of traditional mechanical steering components and potential leak points.

Extra-Long 25-Inch Shaft Utility

Specifically calibrated for high-transom vessel dimensions, the 25-inch extra-long shaft helps support proper propeller immersion in varying sea conditions. This configuration prevents aeration and cavitation during high-speed runs, 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 deep-V hull configurations during long transits.

E-TEC G2 Direct Injection Tech

The legendary E-TEC G2 direct injection system atomizes fuel directly into the combustion chamber for maximum thermal efficiency and the cleanest emissions in its class. This technology results in instant throttle response and strong low-end punch that traditional valve-driven engines often fail to match. You gain the advantage of a cleaner-burning engine that requires zero break-in period and no oil changes, maximizing your time on the water from day one.

81-Amp Digital Charging System

Equipped with a robust electrical system, the K115HGXF delivers 81 total amps with a dedicated 14 amps provided even at idle speeds. This charging capacity easily supports modern fish finders, high-definition GPS displays, and livewell pumps found on modern performance boats. US This can provide the confidence to run a full suite of electronics throughout the day without the risk of draining the primary starting battery while anchored or trolling.

Integrated i-Control Digital Command

The K115HGXF utilizes the i-Control system to provide a smooth and cable-free throttle and shifting experience at the helm station. This digital flight-by-wire interface helps support precise vessel positioning and synchronization, ensuring the engine reacts instantly to the captain’s input. You gain the tactile control necessary for safe navigation through busy harbors or narrow technical channels with the reliability of high-speed digital signal processing.

Simplified 5-Year Maintenance Schedule

Built with high-quality sacrificial anodes and a quad-thermostat cooling system, the K115HGXF is engineered for offshore saltwater durability. The G2 engine features a low-maintenance design that requires no scheduled dealer service for the first 5 years or 500 hours of operation.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
