Evinrude E-TEC G2 150 HP engine

The Evinrude E-TEC G2 150 HP is the lightest, least-expensive of all the E-TEC G2s.

All-New Engine Design

The Evinrude E-TEC G2 150 HP engine’s powerhead is built from a 167-cid (2.7-liter/274cc) 66-degree V-shaped aluminum six-cylinder block. Bore and stroke is 3.386” x 3.100” (86mm x 78.7mm). It continues the 2-stroke technology that Evinrude is famous for and it has greatly improved the fuel efficiency from low RPM to WOT, but most importantly in the mid cruising RPM range, as well. Evinrude says that across the whole RPM range its new engine averages 15% more fuel efficiency than competitive 4-stroke engines.

Based on our tests in July 2016 on 13 boats including center consoles, bay boats, multispecies fishing boats, sportboats and pontoon boats, the new Evinrude E-TEC G2 platforms can go toe-to-toe with any outboard on the market in miles per gallon comparisons in the critical mid rpm range where most boaters run their vessels.

This is big news, because it means that these new Evinrude E-TEC G2 engines have the high-torque at low and mid RPM ranges that have always been the sole domain of 2-stroke engines -- while now being absolutely competitive with 4-stroke engines in fuel efficiency.

In addition to these two key performance characteristics, the new Evinrude E-TEC G2 150 HP has many exclusive features worth noting.

Mission Statement

Evinrude says the E-TEC G2 150 HP is targeted at re-powers and boats that are sensitive to engine weight such as bass, multi-species freshwater fishing boats, bay/flats models for saltwater use, entry-level sportboats and smaller pontoon boats. All of these applications need lightweight and high-torque at the low and mid RPM ranges.

Because the Evinrude E-TEC G2 150 HP is only available with the TRAC midsection that works with conventional cable steering, it is an easy install for re-powers. Owners with boats that already have external steering gear will benefit from a cost savings. It’s also 30 lbs. (14 kg) lighter than an engine with the more sophisticated G2 midsection. All of the other Evinrude E-TEC G2 features are incorporated into the 150 HP, including direct fuel-injection, i-Trim - automatic trim system, auto-winterization and more.

For a multi-species boat like this Alumacraft Edge 185 Sport, the Evinrude E-TEC G2 150 HP is a good option because of its relatively light weight, fuel-efficiency and high-torque at low and mid-range RPM bands.

Features Inspection

1. Conventional Steering

The only aspect of the Evinrude E-TEC G2 150 HP that is different from the other three new models that Evinrude recently introduced is the TRAC midsection. It is the only midsection available on the Evinrude E-TEC G2 150 HP. This conventional midsection makes it easy to repower existing boats with external steering gear available. It also saves about 30 lbs. (14 kg) over the units with internal steering, and it is less expensive. The Evinrude E-TEC G2 150 H.O. is available with either the TRAC of G2 internal steering midsection. All of the other E-TEC G2 engines, 175 HP to 300 HP, are available only with the G2 midsection.

Easy Re-Power Adaptation.

Because the Evinrude E-TEC G2 150 HP comes only with Evinrude’s TRAC midsection, it saves an owner money when re-powering. The conventional TRAC midsection will fit any application.

While the Evinrude E-TEC G2 150 HP does not have the Dynamic Power Steering, it does come with all of the other E-TEC G2 features, including magneto electrical generation, integral oil tank, robust gearcase, digital shift and, as well as high-torque at low RPM, fuel-efficiency and lowest emissions in the industry.

Above the tilt tube, all the wires and harnesses from the helm pass through Evinrude’s patented Dual Axis Rigging Tube, creating a clutter-free stern.

2. Robust Lower Gear Case

Inside are new, more robust gears -- the same ones used on all E-TEC G2 models from 150 HP to 300 HP -- and, on the outside, the housing has a sleek profile for hydrodynamic efficiency. The leading edge of the lower unit is designed to slice cleanly through the water and to keep weeds off the two water pickups on each side.

should help improve planing times. The skeg is cambered to counteract the propeller rotation, eliminating the need for an adjustable trim tab. The Evinrude E-TEC G2 150 HP comes with 2.17:1 reduction gear in the lower unit and is available in 20” (50.8 cm) and 25” (63.5 cm) shaft lengths.

Larger and more robust gears -- the same used on all E-TEC G2 engines from 150 HP to 300 HP -- let the E-TEC G2 150 HP swing a larger propeller and handle the abuse of running in rough conditions offshore. Note the internal digital shifting mechanism in the front of the housing.

3. Precise, Digital Shifting

An important feature on the Evinrude E-TEC G2 150 HP is digital shift and throttle control. The shift module is in the front of the gearcase, where it’s protected from the elements. Digital operation facilitates rigging and gets rid of long cables and linkages that are exposed to corrosion. It also allows operators to precisely and easily set the exact RPM setting required for any maneuver. The digital controls also let owners of multi-engine installations sync their motors.

By locating the digital shift module in the gearcase, Evinrude did away with long cables and linkages found on conventional outboards. The actuator is at the top of the gearcase.

Evinrude E-TEC G2 150 HP controls
The digital controls are smooth and the throttle response with digital system is crisp. This feature is particularly useful in neat vertical throttle installations such as the one seen above which is not particularly ergonomic.

Evinrude E-TEC G2 150 HP itrim
The new Evinrude E-TEC G2 150 HP features an integrated automatic trimming system, i-Trim. The Evinrude ICON controls allow captains to select automatic or manual trim operation.

4. i-Trim

Every E-TEC G2 comes with Evinrude’s i-Trim automatic trim system that trims the engine for the operator. Beginners will welcome this feature. The system automatically trims the boat to its optimal setting at any speed, according to Evinrude. Veteran drivers can override i-Trim simply by using the trim himself or by pressing “Off” on the Evinrude ICON controls.

5. Direct Fuel Injection

Evinrude E-TEC G2 150 HP fuel injectors
Seen from the side of the engine, a bank of fuel injectors is the heart of the direct-injection system -- perhaps the most important aspect of the engine that sets it apart from other outboard motors on the market. Note the injector housing on the left in close proximity to the spark plug.

Evinrude E-TEC G2 150 HP strokes
Every stroke is a power stroke which gives the Evinrude E-TEC G2 150 HP far greater low and mid-range torque than 4-stroke engines.

Evinrude E-TEC G2 150 HP chamber
The Evinrude E-TEC G2 combustion chamber was designed around the injector. The chamber’s shape was contoured to maximize fuel efficiency at all RPM.

Direct Injection.

Rather than trying to adapt an existing block (something other engine makers have done), Evinrude designed the E-TEC G2 engine block from scratch, specifically for direct fuel injection. By working with the University of Wisconsin & utilizing computational fluid dynamics, they were able to optimize the intake, combustion chambers & exhaust system. Each cylinder has its own injector and the spark plugs are placed in close proximity to optimize combustion. The Engine Management Module controls the fuel delivery ensuring that the air to fuel mixture remains 14:1.

This is a close-up of one of the fuel injectors. There is one for each cylinder on the engine and they fire up to 6000 times per second. This enables the optimum fuel flow to be controlled by the EMM (Electronic Management Modul) for each RPM.

Complete Combustion Means Low Emissions.

One measure of this efficient design is the fact that the Evinrude E-TEC G2 has the lowest emissions of any outboard engine on the market. That means virtually all of the hydrocarbons were burned and maximum energy being released from the fuel used. This is why it is so fuel efficient and has the lowest emissions.

Low RPM Efficiency.

Above the main combustion chamber is a small “alcove” chamber where the spark plug and direct injector are located. The small chamber gives the Evinrude E-TEC G2 its efficiency at idle and at low rpm. During stratified combustion, a small amount of fuel is injected into the cylinder. Because it is in such a confined space, and the spark plug is so close, the ignition is fast and complete. This results in maximum power and minimum fuel burn at low rpm.

Better Mid-Range Torque.

The combustion chamber design was engineered after a lengthy study of in-cylinder fluid dynamics conducted by Evinrude engineers and professors at the University of Wisconsin Madison. The new design gives the engine 30% more peak torque, according to Evinrude.

2-stroke engines have always had more low end torque than 4-stroke engines because every stroke is a power stroke. This graph supplied by Evinrude shows the relative difference in power across the RPM range.

The E-TEC G2 150 HP’s Electronic Management Module (EMM) is on top of the motor and controls multiple engine functions including fuel injection. It is water cooled to reduce the temperatures of the internal components for longer life.

6. Electronic Management Module

These days all new engines have them, but Evinrude’s is one of the most sophisticated. Not only does it meter the fuel released into the combustion chambers down to a few bubbles a second, it also controls the i-Trim, the oil lube system, and activates the auto-winterization feature.

No Break-in Period.

Evinrude designed the E-TEC G2 engines with high quality materials & manufacturing processes. The cylinders and pistons are precisely honed and the EMM distributes additional oil so no “break-in” period is required unlike most outboards where this is a mandatory procedure.

The EMM, is raw water cooled -- the only one to do so in the industry -- to help keep electronic components healthy.

Inside the housing we find the electronic components of the EMM. Note the raw water cooling channel down the middle of the unit.

7. Integral Oil Lubrication

On the starboard side of the engine is the largest internal oil tank in the industry. It holds 3 gallons (11 L) of lubricating oil that should last an owner up to 50 hours. Oil flow is precisely regulated by the EMM and distributed at key position within the engine, allowing 3 gallons to last so long -- a full season for most boaters. A read out on the dashboard screen transmits the amount of oil in the tank.

Evinrude equips the E-TEC G2 150 HP with a clear bottle and sight tube for the lower-unit gear lube oil. This lets an owner check the quality of the lube as well as the quantity.

The oil fill is on the top of the engine and can be accessed by taking off the top panel. Two posts for jumpstarting the engine when the need arises are on the front of the engine.

8. Magneto Means More Amps

There is a reason why piston-driven aircraft, race cars and other vehicles that need reliable electrical power use a magneto rather than an automobile-style alternator. Chief among those reasons are reliability and greater power output. Because there are no belts or pulleys to go wrong it is more reliable. Because the magneto is turned by the crankshaft the sheer muscle can be applied to turn a larger armature inside a huge stator producing far more amps than an alternator can produce.

Evinrude strove to reduce moving parts on the E-TEC G2 engines to make it easier to maintain. We saw evidence of both efforts in the E-TEC G2 150 HP’s charging system. The magneto makes 133 Amps of power, 50 of which are a dedicated output. Those 50 Amps go to the house battery to run all of the electrical appliances, lights and navigation aids on the boat.

9. Easy Owner Maintenance and No Dealer Maintenance for 5 Years

Evinrude designed the E-TEC G2 150 HP to not need any scheduled maintenance for 5 years or 500 hours of operation. For freshwater flushing, there’s a fitting for attaching a garden hose on the back of the motor. Additionally, the engine has a self-winterizing feature. When it’s time to put away the boat for the winter, hit the self-winterize function and that’s it. If an unexpected warm day pops up, the engine can be quickly de-winterized and then put away again when the temperatures drop.

10. Anti-Corrosion Feature

Five Year Anti-Corrosion Warranty.

The Evinrude E-TEC G2 150 HP carries a five-year anti-corrosion warranty. There are several reasons why Evinrude can offer this warranty, but the primary one is the titanium oxide coating that is applied electrostatically to the lower unit and exhaust system. Evinrude utilizes stainless steel parts wherever possible and employs several large sacrificial zincs to both protect and warn of strain current in a marina. The paint primer and coatings are state-of-the-art. Everything exposed to saltwater has been protected.

The individual pieces are much lighter and come in seven color choices with 14 available accent graphics. The newest color available is Mossy Oak camo.

12. 5 Year Warranty

A 5-year engine and non-declining corrosion warranty comes with every Evinrude E-TEC G2 150 HP, no matter when it is purchased.


h3>The big news is that based on our 13 tests this summer compared to published numbers of similar boats with other brand engines -- the new Evinrude E-TEC G2 platform appears to be as fuel efficient -- or more so -- in the typical cruising RPM range, as any brand on the market, including 4-stroke engines. While we did not test an Evinrude E-TEC G2 150 HP, we did test a number of boats with the 150 H.O. versions and the 200 HP. We look forward to testing this engine as well as its more powerful sisters.

In saltwater Applications.

The Evinrude E-TEC G2 150 HP is certainly suitable for bay boats and small center consoles with a single engine, and larger center consoles with twins. Here, greater fuel efficiency equals greater range and more time over the fish.

In Freshwater Applications.

Higher low-end and mid-range torque has always been the name of the game and that has always been Evinrude’s long suit. Bass boats, towing sportboats, deckboats, and pontoon boats are all appropriate for this engine. With the improved fuel efficiency of the new E-TEC G2 platform, plus its features such as i-Trim, digital shift and throttle, auto-winterization, a 5 year warranty and all of the rest of it, it becomes a compelling choice, in our opinion.


Increasingly, it is a more attractive option for many people, than buying a new boat. The Evinrude E-TEC G2 150 HP offers the opportunity to get the newest engine on the market, with state-of-the-art features, for about the same price, as brands with older technology and not so many useful features.
