Captain's Report

Contents of Report

engine

We tested Evinrude’s new E-TEC G2 140 HP engine on the Tidewater 198 CC Adventure.

running

The redesigned ventilation plate on the Evinrude E-TEC G2 140 allows rough water transit without ventilation.

Mission

cowling cover

Evinrude has designed a new front-opening cowl, colored side panels, and distinctive air intake for their mid-range 3-cylinders.

Evinrude’s goal was to bring previous G2 technology to the 140-hp engine class. It has digital throttle and shift, direct fuel injection, and internal steering is available, like the other G2s, all of which is previously unheard of in this horsepower range.

These engines have more torque than their 4-stroke contemporaries as well as better emissions and fuel efficiency plus all the features of their larger G2 forebears.

The standard G2 engine features are complemented by cost effective repower options such as the ability to continue to use existing external hydraulic steering and even old cable Teleflex steering in place of Evinrude’s internal steering.

features

Evinrude’s E-TEC G2 140-hp has G2 features similar to its 3-cylinder mid-range family.

outboard running

The Evinrude E-TEC G2 140-HP weighs 390 lbs. (177 kg) and has an excellent power-to-weight ratio.

Because it’s built with an all-new two-stroke, 3-cylinder powerhead, this outboard weighs in at just 390 pounds. There aren’t many outboards in this segment, and some weigh about the same, while others are nearly 80 pounds heavier while offering lower horsepower.

Design

 

drawing
The conceptual drawing demonstrates how two-stroke engines deliver power in one revolution of the crankshaft.

Evinrude has used innovation and advanced technology to improve two-stroke benefits, such as a power stroke in each cylinder for every turn of the crankshaft, fewer moving parts, and light weight to build the new 3-cylinder 140-hp engine.

The advanced technology of computer-aided design to map the shape of the cylinder head for optimal direct injection of fuel, coupled with a water cooled brain module (EMM) that times ignition to lower emissions was the most significant advance in the original G2 line.

Dampening Vibration. A natural concern about 3-cylinder engines is that they might have more vibration than a 4 or 6 cylinder engine. Three-cylinder engines are made by virtually all major light-weight car builders, including Mercedes and BMW, and all have figured out how to reduce vibration to levels of 4 and 6 cylinder engines. Evinrude has done the same with counter weights on each end of the crankcase as well as a three-point bushing system that stops the transit of vibration to the boat and sends it back to the engine body, according to the company.

Shallow-Water Pick-Ups. Evinrude has also redesigned a more efficient lower unit with water pickups for shallow water operation and added a split exhaust which goes through a muffler box at idle and through the prop hub below the waterline when the engine is above idle.

Best Applications

The new mid-range Evinrude E-TEC G2s are ideal for:

• Boats

• Multi-species boats

• Bay and flats boats

• Dual consoles and center consoles

• Pontoon boats

• Tow-sports boats

• Bowriders

• Inflatables and RIBs

    Performance

    We’ve tested Evinrude’s new 3-cylinder G2 mid-range outboards, the 115 HO, the 150-hp, and now the 140-hp on seven different boats. What follows are the latest 140-hp test numbers from our performance and features inspection of the Tidewater 198 CC Adventure.

    running

    Our test captain put the Tidewater 198 CC Adventure through its paces with the new Evinrude E-TEC G2 140-hp engine.

    The Tidewater 198 CC Adventure has a LOA of 19’8” (5.99 m) and a beam of 8’4” (2.54 m). With an empty weight of 1,950 lbs. (885 kg), 56 gallons (212 L) of fuel and two people onboard, we had an estimated test weight of 3,100 lbs. (1,406 kg).

    mid range outboards

    Boats that can take advantage of the new G2 mid-range engines typically have the helm closer to the engine than larger boats, which is why the 95 decibel noise level at WOT - most of which was wind noise in an open boat - is a tribute to the new exhaust system.

    Top Speed. With the Evinrude E-TEC G2 140 outboard powering our test boat, we reached a top speed of 41.8 mph (67.3 kph) at 5500 rpm.

    Best economic cruise came in at 3500 rpm and 24.3 mph (39 kph). It was at that speed that the 4.2 gph (15.9 lph) fuel burn translated into 5.8 mpg (2.45 kpl) and a range of 291 statute miles (468 km).

    For acceleration, the Tidewater 198 got on plane in an average time of 4.2 seconds and went from zero to 20 mph in an average of 5.1 seconds and on to 30 mph in 8.7 seconds.

    Direct Fuel Injection

    3 cylinder

    The 3-cylinder powerhead of the new 140-hp is lighter and has fewer moving parts than any comparable 4-stroke engine yet has equal HP and greater torque.

    At the heart of the new 140-HP is Evinrude’s direct-injection fuel system. It is unlike any other system in class for two reasons:

    First, the injector is actually in the cylinder head and not in the intake manifold like it is in 4-stroke engines. Because of that position, the Evinrude employs a more robust injector that that can spray in fuel at up to 800 psi, compared to just 35 psi for 4-stroke engines in class. The Evinrude injector works with the refinement of a stereo speaker, pulsing up to 100 times a second.

    fuel injector

    The fuel injector reacts to commands from the EMM to time and deliver the precise amount of fuel.

    Second, at low RPM, only a small amount of fuel — like champagne bubbles, according to Evinrude — is injected into the smaller top section of the cylinder. This is called “stratified combustion,” which uses less fuel for more efficiency and cleaner operation.

    At high rpm, the engine switches to what’s known as homogeneous combustion and more fuel is injected to the whole cylinder using the full bore and stroke to produce excellent mid- and high rpm-range torque and power.

    The result is an engine that Evinrude says is twice as fuel efficient under 1000 rpm, and from 15% to 50% more efficient up to wide open throttle.

    cylinder head

    Cylinder head technology dates back before the hemi engine- long before computational fluid dynamics allowed leaps in efficiency employed by the G2s.

    Torque

    The rotational equivalent of linear force, torque has distinguished Evinrude’s superior 2-strokes from 4-stroke design. More force applied at the prop means quicker time to plane and better responsiveness.

    Features

    Advanced Oil Lubrication System

    plastic oil

    The plastic oil reservoir below the fuel filter has enough capacity to last an entire season for most boaters.

    There are other important features to the new Evinrude engine. One is the onboard oil reservoir, which holds 1.9 gallons.

    top cowling

    Evinrude has made it easier to remove the top cowling with a front-pull panel.

    Once the top cowling section is removed, the yellow oil-fill cap is visible on top of the engine. When the reservoir is filled, the oil supply will last for 50 to 60 hours of engine run-time, a whole season for most boaters, and usually it’s even longer for low-rev boats which spend about 60% of their time under 1000 rpm.

    cowling removed

    With the top cowling removed, the yellow cap oil fill and internal rigging connections are revealed.

    Oil is not mixed with the fuel. Instead, lubrication is its own completely separate system, sending a carefully metered amount of oil through clear tubes to bathe the cylinder walls in clean oil as needed.

    buckets

    4-stroke engines are lubricated with recirculated oil, which becomes increasingly contaminated as time goes on and must be changed every 50 to 100 hours.

    The Evinrude engine never needs oil changes and its oil is always clean, reducing the chance for cylinder wear.

    emm

    Evinrude’s water cooled EMM or electronic brain is programmed to “double oil” the engine during initial break-in of 2 ½ hours.

    The new Evinrude 140 needs no break-in period — 4-stroke engines permit only limited revs for the first few hours.

    A tiny amount of oil is burned in combustion, and because it is added to the exhaust, it’s included in the emissions of the outboard. On 4-stroke outboards, boaters and dealers have to dispose of dirty crankcase oil.

    The result is that the Evinrude outboards—already the lowest-emission outboard available—are even cleaner than the competition.

    jump start

    Convenient jump start poles below the service cowl are indicated by the red arrows.

    Under the removeable top cowling are the jump start posts, rigging connections for the fuel line, an external oil tank, the forward freshwater flush line, the Evinrude proprietary network connection controlling throttle and shift, and the low-oil-level alert connection. There is also the NMEA 2000 connection to the boat’s systems to integrate with helm units from Simrad, Lowrance, Garmin, and Hummingbird.

    Winterization

    icon display

    The ICON engine display touchscreen winterizes the G2s with a single tap.

    Automatic Winterization. The engine can be readied for offseason storage with a tap of the Evinrude iTouch display or the BRP eLink smartphone app, while the engine is running, either hooked up to fresh water or at the launch ramp in fresh water. This means that owners can winterize their own engines without the cost and hassle of taking the engine back to the dealer.

    Magneto Charging System

    magneto charging system

    The magneto charging system generates enough juice beyond engine needs to dedicate 14 amps of charging to house batteries at idle, or 22 amps at WOT.

    On the top of the engine under the black plastic cover is a magneto, which uses simple coils and magnets under the flywheel instead of an alternator. It has fewer parts and there are no pulleys, belts, or brushes to wear out or break. This is why magnetos are used on Formula One and Indy racing cars as well as on propeller-driven small aircraft.

    Gear Oil Reservoir

    gear oil

    The milky white appearance of gear oil contaminated by water is unlikely in Evinrudes because of an expansion tank wich takes on the heated oil.

    Water in the lower-unit gearcase oil, shown draining above, is a major cause of engine failure. This happens for two reasons: either the oil level is low in the lower unit, allowing condensation to contaminate the oil, or a seal is compromised. Evinrude has solved both of those issues with an expansion tank for gear oil.

    gear oil

    The gear oil tank allows for expansion from heated oil and constantly keeps the lower unit topped off, avoiding condensation and seal failure.

    Evinrude uses an Ultra-HPF gear fluid, which can continue to lubricate even if it’s contaminated by up to 25 percent of its volume with water.

    seal failure

    This competitor’s engine had a seal failure due to the fishing line displayed by the technician, which was wrapped around the shaft resulting in a blown seal.

    Regular Gas

    The outboard runs on 87-octane fuel and has an internal fuel filter that also functions as a fuel-water separator.

    white canister

    The white canister is a 10-micron fuel filter which eliminates the need for external filters and has a water detector that notifies the operator of contaminated fuel.

    Redesigned Lower Unit

    lower unit

    The lower unit has been redesigned with larger pickups moved lower and further forward, to allow the boat to run with the engine positioned higher, something shallow-water anglers will like.

    The straight leading edge is designed to shed weeds. Anodes are placed prominently throughout, and the anti-ventilation plate has been shortened and positioned further aft to permit better water flow around the prop and still stop ventilation in rough conditions. Evinrude tells us that in normal conditions this allows the boat to stay on plane at lower speeds.

    shaft length

    Shaft length is 20” (50.8 cm) or a long shaft of 25” (63.5 cm) is available. The props being fit with the mid-range engines is typically a 14.5” x 19” (36.8 cm x 45.72 cm) RX3.

    Internal Power Steering

    internal

    Evinrude’s introduction of internal steering is an industry first.

    Internal power steering is available on the 140. This is a major advancement in outboard engine design, and makes installation and repower much easier and less costly.

    Repower has provided repower buyers with the ability to use the new engines with other manufacturers’ pre-existing steering to keep costs down. Namely, the outboard has a through-tube tilt tube for use with anti-feedback cable steering. It can also be used with bolt-on external hydraulic steering.

    Dynamic Power Steering

    dynamic power steering

    Dynamic power steering means the hydraulic steering assistance is adjusted for the speed of the boat.

    In the many boats we’ve tested with Evinrude’s internal steering, the steering system was responsive and each turn of the wheel caused the boat to react immediately.

    red arrow

    The red arrow indicates the internal position of the worm gears for the power steering system.

    Helical worm gears over worm gears make for integrated power steering that gives excellent response. Evinrude’s dynamic steering lets the owner adjust the feel of the steering through the ICON touch display as the boat moves from low to high speed.

    icon

    Evinrude’s ICON engine display has customizable power assist (right side of screen) on the touchscreen.

    Clean Transom Installation

    rigging

    A single rigging tube connected to the mount allows the engine to turn without chafe on the rig.

    A dual-access rigging tube is fixed to the mounting bracket, so it stays put, while allowing the engine to rotate independently, providing for a cleaner transom and less wear on the components that connect the engine to the boat. There are no primer bulbs or power-steering hoses going through it.

    pin

    The pin indicated by the top arrow immobilizes the steering to keep the outboard from flopping to one side when it’s raised for trailering. The bottom arrow is where the pin is stored on its tether when underway.

    iTrim

    tilt

    The new Evinrude E-TEC G2 outboards tilt up to 81-degrees to lift the entire lower unit completely out of the water, key for longevity in the marine environment.

    red buttons

    The red buttons on the outboard activate the tilt mechanism for the motor to go up or down. The tilt and trim can also be activated from the helm DTS. The round tube below the buttons houses the gears for the tilt and iTrim.

    touchscreen

    iTrim can be turned on via the ICON touchscreen, automatically levelling the engine to assist the boat onto plane and keeping it there.

    Evinrude included the iTrim automatic trim system in these outboards, helping the boat perform the way it should even with a novice at the wheel. Simply push the button for iTrim and the boat automatically trims the boat for optimum performance at all speeds.

    Exhaust

    muffler box

    The 140 has the same muffler box on the upper exhaust (blue arrow) as the other 3-cylinder G2s. However, it does not employ the RAVE system of the 150-HP 3 cylinder.

    The outboard’s quiet operation is due to the way the exhaust is managed. An internal muffler box on its port side vents aft, and quiets the engine at idle speeds. Above idle speed the engine exhausts at the propeller hub. In our tests, we have found the new Evinrude G2 outboards to be as quite as 4-stroke engines in low and mid RPM ranges.

    Focused Motor Mount

    motor mounts

    Evinrude’s new focused motor mounts (green arrow), one on either side of the engine, are angled at 45-degrees, and a third is above with two bushings.

    To quell vibration on this three-cylinder engine Evinrude has designed what it calls a “focused motor mount” that isolates the powerhead from the mounting bracket to reduce the vibration transmitted to the boat.

    Color

    running

    All-white engines are available for the first time in the G2 line.

    Another feature that’s been added, top to bottom in the E-TEC G2 line, is that the engines are now available with a white exoskeleton, to color match more boats out there.

    black outboard

    The Zodiac test boat from our test of the 115 HO had an engine dressed in black pre-test.

    top panel

    This is the same Zodiac boat and engine after testing with silver side skins and a new top panel added - a demonstration of how easy it is to change the engine’s color scheme.

     

    And like all E-TEC G2 outboards, the side and top panels can be color matched to the boat, with a wide variety of colors and accent striping available.

    Corrosion Resistant

    engine block

    The aluminum engine block is epoxy coated and the lower unit is coated with titanium oxide to dramatically reduce corrosion.

    The blocks are cast from high-grade aluminum alloy and only stainless steel fasteners are used throughout for added corrosion protection.

    Evinrude E-TEC G2 140 HP

    Some of the largest anodes we’ve ever seen in class are installed on the lower unit for protection in marinas with stray current.

     

    Evinrude stands by the outboards with a 5-year corrosion warranty that is at least a year longer and more inclusive than any other outboard warranty. Before buying an outboard for saltwater applications, read the fine print and see what we mean.

    new air intake

    The distinctive new air intake of the new 3-cylinder engines brings in cold air and not only uses it to cool the engine but actively vents out hot air.
