Evinrude has long been at the forefront of outboard engine technology, sticking with and perfecting efficient direct injection two-stroke technologies while others looked elsewhere for performance gains, investing in costly new platforms including four-stroke technology. But none have come close to the torque, fuel efficiency and complete integration Evinrude has achieved in its latest G2 engines.

Evinrude has raised the bar by going back to the beginning and starting with a clean sheet of paper. The objective was to build an engine that surpassed all existing benchmarks by a considerable margin. By sticking with the two-stroke technology that produces twice as many revolutions as four-strokes, thus providing better power output, Evinrude has produced an engine with even better torque, acceleration and fuel efficiency than its already impressive G1 engines.


FIRST LOOK

The G2 engine is a striking looking unit consisting of multiple cowling parts with two sides and a top coming together to provide a futuristic look that also increasing its functionality with improved airflow over critical engine components. The cowling panels are surprisingly light, dampen sound well and are available in five different base colours with 14 accents offering owners a way of matching their boat hull and engine colour. Some manufacturers have also partnered with Evinrude to create custom colours to suit their boat/motor/trailer packages.
The panels can be removed via six screws which remain with the cowling and, consequentially, can’t get lost.

The other noticeable aspect missing on this new G2 engine is the obligatory wiring harness and hydraulic unit that normally messes up the installation of outboard motors. Evinrude has designed the engine with fly by wire controls and hidden the power assisted hydraulic steering cylinder inside the swivel bracket, a first for any outboard manufacturer. The result is impressive removing the need for the external steering cylinder, providing better reliability and cleaner more simplified rigging. The inbuilt dynamic power steering also has three settings enabling the steering feedback to be adjusted to suit the owners preference. Coupled with the automatic speed steering input which adjusts the steering effort depending on the speed of the boat you have a very responsive package.

The more traditional transom mounting bracket has been replaced by a sturdier, stiffer arrangement that reduces twisting and flexing resulting in better high performance operation.

INTERNALLY
Underneath the new external look is a completely redesigned block engineered to maximise combustion and reduce overall fuel consumption. The 250hp we tested is built on a 3.4-litre V6 platform and is normally aspirated which means no superchargers or turbos.

Evinrude has designed the block around the injection process as opposed to designing a block and then adding injection points. This has increased its efficiency as well as making it cleaner burning. In conjunction with the University of Wisconsin Madison, in the US, Evinrude simulated what happens inside an engine and was able to experiment with various fuel delivery locations and mix ratios before settling on a system where the fuel is pumped directly into the combustion chamber using an in-cylinder injection process. This is underpinned by the existing Fast Rise Inducted Ignition system producing a higher energy and longer lasting spark that improves the fuel burn.

Evinrude has left no stone unturned with the addition of a revised gearbox, casing and water intakes improving on water performance and engine cooling.

SERVICING
Evinrude has impressive credentials on servicing with Generation One engines only requiring servicing every three years or 300 hours and they’ve managed to improve on this with the changes made to the Generation Two design stretching service intervals to an incredible five years or 500 hours. In addition there is no break-in period on these engines so as soon as you hit the water, you can give them plenty.

They’ve also included an inspection hatch for owners wanting to double check some components or who have a tendency to run over fishing line which can sometimes ruin some of the seals around the prop.

PERFORMANCE
We tested the 253kg Evinrude E-Tec G2 250 on a 6.8m Edgewater 205 centre console fishing boat with four people onboard and approximately 160 litres of fuel. We drove the boat on the beautiful Cowan Creek in calm conditions with very little wind and the initial impressions were good. From idle, when the motor was sipping just 0.5L/hour, it took about three-seconds to have the centre console on the plane.

Pushing the fly by wire throttle forward and the torque was immediately evident with a rapid acceleration onto the plane. Once up and running the mid-range was impressive with more torque available at any rpm. The engine immediately kicks in and runs hard. Engine noise has been dampened compared to the equivalent G1 model but at WOT (Wide Open Throttle) it was still evident.

When you’re ready to pack up, the power trim on this engine allows you to trim the engine up quickly and to a massive 81 degrees. This allows on water users to trim the skeg entirely out of the water reducing fouling and corrosion.
