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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
