Evinrude has introduced a new line of E-TEC second generation or G2 engines based on a 1.865-liter three-cylinder in-line block of new design. This new E-TEC G2 three-cylinder will be offered in models with horsepower designations of 115 High-Ouput, 140-HP, and 150-HP. These new three-cylinder models will use electronic shift and throttle Evinrude ICON II EST remote controls. Having electronic shift and throttle control in a 115-HP engine is a new option, not available on any other brand's 115-HP engine. A special side-mount EST control is also introduced.
These new three-cylinder E-TEC G2 engines use the innovative G2 engine mounting with integral hydraulic steering and improved rigging, and they can also be ordered with the integral electric power-boast steering option. Some models will be available with tiller steering.
Several boating reviewers who have actually seen and used the these new G2 three-cylinder engines have commented that the engine noise is reduced compared to earlier E-TEC engines, although no measured data is provided.
Engine weight is still unknown. And, as always, the MSRP is not clearly mentioned.
Evinrude also announced that all E-TEC G2 engines will now be available with a choice or white or slate gray engine frames. I think the all-white versions will be a hit.

New Evinrude E-TEC G2 Three-cylinder Engines
Re: New Evinrude E-TEC G2 Three-cylinder Engines
Here is a link to an Evinrude presentation about their new 2020-production year products:
https://youtu.be/W4IsP9dADsk?t=139
The link above skips several minutes of a montage of product shots. This presentation is packed with information; viewing is highly recommended.
The presenter reveals that in the 150-HP model of the new three-cylinder, the engine uses a RAVE valve--ROTAX Adjustable Valve Exhaust--adapted from Evinrude's sister company, ROTAX, and used for years in BRP Snow-mobiles. The 150-HP new E-TEC G2 three-cylinder is lighter by at least 50-lbs compared to other 150-HP engines on the market now.
The new three-cylinder E-TEC engines will have internal (under the cowling) 1.9-gallon oil tank, which often will be sufficient for a full-season of engine use.
Noise, vibration, and harshness (NVH) was specifically addressed in these new engine. These three-cylinder engines use balancing gears at both ends of the crankshaft to reduce inherent vibration in the in-line engine.
A plot of engine horsepower at the propeller shaft as function of engine speed for the new three-cylinder E-TEC 115 H.O. engine and 115-HP competitors was also presented. The plot of horsepower showed a considerable advantage at mid-range engine speeds for the Evinrude E-TEC.
If the 115 H.O. is already make 125-HP, then pushing it to 140-HP shouldn't be too much harder. And hitting 150-HP seems within reach. With a 1.865-liter displacement, at 150-HP each liter produces 80.4-HP/liter . In the E-TEC legacy V6 a 3.4-liter engine was making 300-HP, or 88.2-HP/liter. The 150-HP three-cylinder has the added enhancement of the RAVE technology working for it, so the push to 150-HP rating seems quite reasonable. Snowmobile two-cycle-power-stroke engines with RAVE technology are making even higher power per liter.
During the latter portion of the presentation (at 10:40 from start) a presenter talks about reliability testing. Todd Craft, Director, Project Engineering, says:
There are two ways to interpret that statement: nearly 100-engines were tested to about 300-hours each, for a total of 30,000 hours of testing of the engine in development. Or, nearly 100-engines were each run and tested to 30,000-hours.
A period of 30,000-hours is 1,250-days of 24-hour-a-day testing--about 3.4-years. It seems impossible that 100 engines could have been run 24-hours a day for over three years, so I must infer that the testing regime was to test 100-engine for 300-hours.

Re: New Evinrude E-TEC G2 Three-cylinder Engines
This is such great and refreshing news to the marine outboard market.
With many (and more) of the larger G2 features included in this horsepower range, Evinrude has really come to market with something original.
The 1.9 gallon oil reservoir is a very compelling feature, not only freeing up space of a remote oil tank, but the included hose as well.
Integral hydraulic steering and electronic shift and throttle control in these 3 lower horsepower outboards is pretty significant in my opinion.
Having released propellers specific to this product launch also tells me that Bombardier did their homework.
I know a 'White Paint Job' doesn't do a thing for whats underneath, but I really expect to see these new releases on a lot of smaller bay boats, flats boats, and smaller center consoles, especially if the claim of 'over 50 lbs lighter than competing four stroke outboards' is true.
I have a 1986 Boston Whaler 18 Outrage powered by a Evinrude E-TEC 115, and a 1988 Boston Whaler 15 powered by a Yamaha F70.
Both work out great respectively. I was mulling over re-power considerations when the day comes to re-power the 18 Outrage.
The G2 150 is just a bit heavy for my preference on a classic 18 Outrage . . . but with this new in-line 3 cylinder light weight 150, Evinrude has me very excited to see how this new motor shakes out.
Think about how ironic it would be to have a Boston Whaler 18 Outrage of over 30 years, with a such a technologically advanced outboard hanging on the transom. Talk about the best of both worlds.
Great job Evinrude, this is great news.

I'm thinking a new white G2 150 3 cylinder would be great on my 1987 Outrage 18.

Re: New Evinrude E-TEC G2 Three-cylinder Engines
With my normal constraints abandoned, I have had thoughts about how a pair of E-TEC three-cylinder 140-HP engines would look on the Whaler Drive of my REVENGE 22.

I’ve had the same thoughts for my V-22.
Set of these 140 or 150s vs a 300 G2 what would you do?

Re: New Evinrude E-TEC G2 Three-cylinder Engines
I find that horsepower curve very interesting. First, let's assume it's accurate. Horsepower is defined as (torque * RPM)/5252. At 4500 RPM the engine is making 124 HP, thus the torque is 124 * 5252 / 4500 = 144.7 foot pounds. When the RPM increases to 5000, horsepower output increases only very slightly to 125, so torque must be going down... 125 * 5252 / 5000 = 131.3 foot pounds. At 5500 RPM torque is down to 119.4 foot pounds, and at 6000 RPM it's only 109.4 foot pounds.
It's not unusual for torque to decrease as engine speed gets up into its top range, but it's not usually so dramatic like this 25% decrease. What this tells me is that the engine is good for a lot more power, perhaps 150 HP at 6000 RPM. They've clearly tweaked the engine controller to limit the torque above 4500 RPM, and thus limit the horsepower to 125.
I'm not saying that's a bad thing. This engine would totally kick ass getting my boat on plane!

Would electronic throttle mean electronic cruise control? No wake mode like on a jet ski?

Re: New Evinrude E-TEC G2 Three-cylinder Engines
I think these engines bring a lot to the market. I am curious that they went with 140 and 150hp instead of 135–150hp.

No. Electronic shift and throttle means there are electrical motors that move the levers on the engine that control the throttle and shift.
Boat throttles don’t have a spring-return to idle. They stay where you set them—unless there is a lot of vibration and the throttle handle friction doesn’t hold the setting.
Re: New Evinrude E-TEC G2 Three-cylinder Engines
An article about the new three-cylinder G2 E-TEC engines on BOATTEST.COM says the ROTAX engines (a sister company to Evinrude) which are similar to the new G2 engines have such great fuel economy they are being used in military drone aircraft.

Re: New Evinrude E-TEC G2 Three-cylinder Engines
So what is the real world performance benefit of the much higher HP at lower rpm?
Let's say a 2000 Dauntless 160, would the new Evinrude 115 motor run a significantly higher pitched and or a larger diameter prop compared to the Mercury 115 Pro XS that also has the same peak HP?
Is it just fuel economy being able to run a larger prop at a lower rpm?
Would the benefits outweigh the additional 30 pounds or so of the Evenirude compared to the Mercury on an older hull designed for lighter outboards?
Not ready to repower right at the moment but dreaming and trying to educate myself.
Currently I have a 2008 Yamaha F90 which is adequate but underwhelming.

An engine with more power available at lower RPM ranges will be able to maintain engine speed under load from the propeller. I suggest you read my article on propeller power curves at
http://continuouswave.com/whaler/refere ... Curve.html
When the power needed to turn the propeller is greater than the power the engine can provide, the engine stops accelerating. The engine then decelerates until its power output equals the power required to turn the propeller. For many boats this can mean the boat cannot stay on plane at low speeds. The engine is unable to maintain speed—called lugging—and the boat speed drops, the boat comes off plane.
Boats do not have transmissions with variable gear ratios, so their engines must have good low-speed torque and power. An engine that must be able to accelerate to 6,000-RPM to produce its rated horsepower is unlikely to be able to produce a significant fraction of its rated power at 2,500-RPM, which is where it may stop its acceleration and lug down.
