The powerhead of the Evinrude G2 115 HO features an inline
three-cylinder block cast from high-strength, corrosion-resistant
materials. The 1.9-liter displacement represents a significant increase
over the previous 1.7-liter V4 engine, providing enhanced torque and
power throughout the operating range. The cylinder bore measures 98 mm,
and the piston stroke is 82.6 mm, contributing to the engine's
oversquare design which reduces piston speed at higher RPM and increases
component lifespan.
The pistons are manufactured using an alloy originally developed for
NASA's space program that is significantly stronger than traditional
materials, providing exceptional durability and heat resistance. As a
two-stroke engine, it utilizes a reed valve induction system with
advanced direct fuel injection.
A key innovation on this powerhead is the incorporation of a pair of
balance gears that cancel primary engine vibration, resulting in
exceptionally smooth operation at all RPMs. The powerhead is designed
for long life and reliability, with fewer moving parts than comparable
four-stroke engines, eliminating valves, camshafts, belts, and timing
mechanisms that require adjustment or replacement.
The fuel system is centered around Evinrude's advanced E-TEC direct
injection technology with stratified low RPM combustion mode.
High-pressure fuel injectors, precisely controlled by the EMM, deliver a
finely atomized fuel spray directly into the combustion chambers. This
system is optimized to produce a uniform dispersion of very fine fuel
droplets that encourage efficient and complete combustion.
At low RPM, the engine operates in a stratified combustion mode,
creating a controlled fuel cloud near the spark plug for exceptional
fuel economy, reduced emissions, and idle smoothness. The engine is
designed to operate on standard 87 octane unleaded gasoline. The fuel
system includes advanced digital controls and can be integrated with
iTrim automatic trim optimization for enhanced efficiency. The vapor
separator and fuel pump assembly are designed for reliable operation,
with all fuel system components easily accessible for service.
Lubrication is managed by a sophisticated multi-point targeted oiling
system. An electric oil pump, controlled by the EMM, draws oil from the
integral tank and injects it directly onto critical engine components
based on real-time engine speed and load demands. This system ensures
precise lubrication while minimizing oil consumption and emissions. An
on-engine oil tank with a capacity of 1.9 gallons (7.2 liters) is
positioned under the powerhead for easy access through a snap-off top
panel.
The tank holds enough oil for an entire season of normal use,
eliminating the need for remote oil tanks and transom-mounted
reservoirs. The recommended lubricant is XPS Marine XD100 oil, a fully
synthetic oil specifically formulated for E-TEC G2 engines to maximize
performance and reduce carbon deposits. The system eliminates the need
for oil changes, oil filters, and the disposal of used crankcase oil,
contributing to the engine's maintenance-free ownership experience.
The cooling system is a pressure and temperature-controlled water-cooled
design. A high-capacity water pump in the lower unit circulates water
through extensive water jackets in the cylinder block and cylinder head.
The system uses a two-stage design controlled to maintain optimal
operating temperature across all engine speeds. A freshwater flushing
port is integrated into the engine design, allowing easy connection of a
garden hose for flushing the cooling system after operation in salt or
polluted water.
The EMM continuously monitors engine temperature and will activate the
S.A.F.E. (Speed Adjusting Friction Elimination) limp-home mode to reduce
RPM and protect the engine if an overheat condition is detected,
allowing the operator to return to port at reduced speed. The cooling
system also manages temperatures for the EMM and other critical
components, ensuring reliable operation in all conditions.
| Mid Section and Lower Unit |
The mid-section houses the driveshaft and exhaust tube, connecting the
powerhead to the lower unit. Unlike the larger V6 G2 models, the
1.9-liter G2 models feature a conventional midsection with a hydraulic
trim ram rather than the helix device found on larger engines. The
midsection incorporates a standard steering pivot with a steering arm
that accepts cable or hydraulic steering input, with optional iSteer
Dynamic Power Steering available as an integrated system.
The lower unit contains a new 4.25-inch gearcase designed specifically
for the 1.9-liter power band, with a 2.08:1 reduction ratio. The
gearcase is robust and filled with high-performance lubricant, featuring
a forward-neutral-reverse shifting mechanism. Gearcase drain and fill
screws must be torqued to 60 to 84 lb-in (7 to 9.5 Nm) during service.
Anode and water intake screen screws require 10 to 14 lb-in of torque.
The exhaust is routed through the propeller hub for efficient discharge
and reduced noise.
The Evinrude G2 115 HO is equipped with Power Trim and Tilt as standard
equipment, with both automatic and manual operation available. This
hydraulic system allows the operator to adjust the engine angle for
optimal boat performance, acceleration, and shallow-water operation. The
trim range is from -6 deg to +15 deg, providing precise adjustment of
the boat's running attitude.
The tilt range extends to 81 deg, offering ample clearance for beaching,
launching, or trailering. The system includes iTrim, an automatic trim
optimization feature that adjusts engine angle for optimal performance
and fuel efficiency based on operating conditions. Multiple engine
installations can be equipped with Evinrude's i-Dock system that uses a
joystick for low-speed maneuvering, allowing the boat to move sideways
or in any direction.
Proper propeller selection is critical to allow the engine to operate
within its 5000-6000 RPM full-throttle range under normal load
conditions. Evinrude developed two all-new propeller families
specifically for the 1.9-liter G2 engines: the RX3 and RX4 series. The
RX3 is a three-bladed propeller optimized for all-around performance and
fuel efficiency, making it the standard equipment choice. The RX4 is a
four-bladed stainless steel propeller designed for maximum traction and
rough water performance, producing superior bow lift and maintaining
grip in turns.
The RX4 features Variable Vent Port (VVP) technology and is available in
various pitch sizes from 14 inches diameter and up. The specific
propeller selection depends on boat type, intended use, and load
conditions. The propeller nut must be torqued to 70 to 80 lb-ft (95 to
109 Nm) for secure installation. For multi-engine installations
requiring counter-rotation, specific propeller configurations are
available.
Minimum mounting centers are 26 inches (660 mm).
Shaft Length Options: 20 inches (508 mm) and 25 inches (635 mm)
Weight: 390 lbs (177 kg), 401 lbs (182 kg), 415 lbs (188 kg), and 426
lbs (193 kg)
The Evinrude G2 115 HO is engineered for minimal maintenance
requirements, representing one of the most significant ownership
advantages of the E-TEC system. A key benefit is no scheduled dealer
maintenance required for the first five years or 500 hours of normal
recreational use. The engine features an auto-winterization mode that
simplifies long-term storage, eliminating the need for manual fuel
system treatment.
There are no oil changes, oil filters, or valve adjustments required
over the life of the engine. The EMM continuously monitors engine
systems and stores fault codes for diagnostic purposes. Recommended
pre-launch checks include verifying oil level in the on-engine reservoir
through the digital gauge (there is no visual check) and inspecting for
any signs of damage or corrosion.
Routine maintenance items after the initial five-year period are
minimal, with annual or 100-hour service intervals recommended
thereafter. The engine includes a limp-home mode that activates if the
engine overheats or malfunctions, allowing reduced-speed operation to
return to port. The cooling system can be flushed using the integrated
freshwater flushing port. Battery requirements should follow
manufacturer specifications for reliable starting and electronics
support.
