| General Technical Data |
The Evinrude E-TEC 150 G2 is a second-generation direct-injection two-stroke outboard engine representing a comprehensive re-engineering of marine propulsion. This V6 powerhead integrates advanced digital control, sophisticated combustion management, and a streamlined rigging architecture into a single, cohesive system.
The G2 design philosophy moves beyond the powerhead alone to encompass a complete propulsion solution, including integrated steering, digital controls, and a dedicated diagnostic interface. It delivers 150 Hp with a focus on exceptional low-speed torque, class-leading fuel efficiency at cruise, and a substantial reduction in regulated emissions.
The engine is built for simplified ownership,
featuring extended maintenance intervals and a user experience centered
on the ICON touch-screen command center.

| Cylinder Block |
The cylinder block is a closed-deck, high-pressure die-cast aluminum alloy structure with a 66-degree V6 bank angle. The closed-deck design provides maximum structural rigidity, ensuring cylinder bore stability under high thermal and mechanical loads. The cylinder bores utilize a proprietary Nickel-Silicon-Carbide (NSC) composite coating applied via a plasma arc process.
This coating creates an extremely hard, low-friction wear surface integral to the aluminum, eliminating heavy iron liners and improving heat transfer. A forged steel crankshaft runs in four main bearings within this rigid assembly.
| Cylinder Head and Valves |
This engine employs the E-TEC direct injection system and operates without intake or exhaust valves. Gas exchange is governed by precise piston-port timing. Each cylinder is served by its own aluminum alloy cylinder head. The combustion chamber is a compact, machined design optimized for the stratified charge combustion process.
At low RPM, fuel is injected late in the compression stroke to create a rich, ignitable cloud near the spark plug within a lean overall mixture. This design maximizes efficiency and minimizes unburned hydrocarbons. The head incorporates coolant jackets and mounting points for the direct injector and spark plug.
| Fuel System |
The fuel system is a high-pressure direct injection system. It consists of an in-tank lift pump, a engine-driven mechanical high-pressure pump, a fuel rail, and individual solenoid-controlled injectors for each cylinder. Fuel injection pressure operates between 500 and 700 psi. The system is managed by the EMU, which controls the precise timing, duration, and pattern of multiple injection events per cycle.
This allows for optimized combustion across the entire RPM and load range, from a super-lean stratified charge at idle and trolling to a homogeneous charge at wide-open throttle. This precision eliminates fuel wash-down of cylinder walls and prevents raw fuel from escaping out the exhaust.
| Lubrication System |
The lubrication system is a multi-point targeted oiling system. A programmable, positive-displacement oil pump supplies 100% synthetic Evinrude XD100 oil to specific critical bearing points: crankshaft mains, connecting rod bearings, and piston pins.
Oil is not pre-mixed with fuel and is not introduced into the intake charge for general cylinder lubrication. Instead, cylinder walls are lubricated by a precisely metered oil film. The EMU calculates oil delivery based on a sophisticated algorithm using engine load, RPM, temperature, and running time, ensuring optimal protection with minimal consumption and virtually zero visible smoke.
| Cooling System |
The cooling system is a dual-circuit, closed-loop design for the powerhead. A raw water pump cools the exhaust system. A separate, sealed loop filled with a glycol-based coolant circulates through the cylinder block and heads. Heat is transferred between these two circuits via a heat exchanger.
This closed-loop system maintains a consistent and optimal engine temperature of approximately 160 F (71 C), improving combustion efficiency, reducing thermal stress, and preventing saltwater scale and corrosion inside the engine's critical water passages. The system is self-bleeding and requires minimal maintenance.
| Other Systems |
Digital Control System: The engine is governed by dual processors: the
Engine Management Unit (EMU) and the Rigging Management Unit (RMU). This
system manages all functions via the ICON touchscreen interface,
including throttle, shift, trim, steering, and system diagnostics.
Integrated Hydraulic Steering: The iDesk system is built into the
engine's steering pivot.
It is a 100% electric, adaptive hydraulic system requiring no external
pumps, hoses, or hydraulic fluid at the helm, providing speed-sensitive
steering effort. Power Trim and Tilt: A fully integrated,
software-controlled hydraulic system provides a maximum tilt range of 81
For beaching and trailering.
Gearcase (Lower Unit): The high-strength PTO (Power Take-Off) gearcase
features a dual-exhaust discharge port design and a hydrodynamic torpedo
shape to reduce drag. It houses a 15-spline stainless steel propeller
shaft. Rigging: The G2 uses a single, large-diameter "rigging tube"
containing all necessary electrical and fuel connections, drastically
simplifying installation.
| Dimensions and Weight |
Dry Weight (Approximate): Ranges from 496 lbs (225 kg) to 541 lbs (245
kg). The specific weight depends on the shaft length (20 or 25 inches)
and the inclusion of the Integrated Hydraulic Steering module. Shaft
Lengths Available: 20 inches (508 mm) and 25 inches (635 mm).
Overall Profile: Features a distinctive, steeply raked "slam" hood
design for a low visual profile. The integrated design presents a clean,
single-unit appearance from the steering pivot to the cavitation plate.
| Maintenance Data |
Scheduled Dealer Maintenance: No dealer-scheduled maintenance is
required for the first three years or 300 hours of operation.
Spark Plugs: Iridium-tipped long-life plugs have a service interval of 5
years or 500 hours.
Fuel Filter: A spin-on water-separating fuel filter is located on the
engine. The EMU monitors pressure drop; replacement is advised at
300-hour intervals.
Water Pump Impeller: The raw water pump impeller is housed in an
external, serviceable module. Recommended inspection/replacement
interval is 5 years or 500 hours.
Gearcase Lubricant: Drain and refill every 5 years or 500 hours.

systems.
Diagnostics: The ICON system provides full system diagnostics, active
warning alerts, and a detailed maintenance log.
