Evinrude E-TEC Outboard Engines

A new era in outboard engine technology with low maintenance, durability, quality and reliability, less sound and lower emissions all in a sleek new styling

Miami Beach, Florida, Feb. 12, 2003 - With the launch of Evinrude® E-TECTM technology, Bombardier Recreational Products begins a new era in the outboard engine industry. Evinrude E-TEC is the future of outboard engine technology. Five innovative and distinct features of E-TEC sets its performance apart from current industry offering to truly make it unique:


  • Whisper-quiet operation
  • Extremely low maintenance
  • Durability, quality
  • and reliability
  • Styling

E-TEC can apply to the lowest horsepower outboards, while maintaining excellent power and torque, remaining environmentally-responsible and providing whisper quiet operation.

Currently, the Evinrude line of E-TEC includes 40-, 50-, 60-, 75- and 90-horsepower models, filling the need for recreational boating mid-range power. By model year 2005, the power lineup will be complete through the big V-6s.

Living Up to the "Environmentally-Responsible" Pledge

The complete line of Evinrude E-TEC engines is designed to be California Air Resources Board (CARB) 3-star compliant outboard engines.

The stratified fuel combustion chamber is key in this advanced technology. Fuel reaches the exhaust port only after it has closed, at one-half the time of traditional direct injection engines. This means the fuel charge does not escape the combustion chamber - especially during idle - as it is burned and turned into power. The stratified combustion chamber also offers better fuel efficiency because of its precise fuel flow. The E-TEC system senses when to change the number of droplets into the chamber, depending on the engine needs, which is extremely fuel efficient.

The electronic "governing" of the idle speed ensures a smooth running ride. The electronic compensation system regulates a precise fuel flow control for the temperature block, barometric pressure and injector variation.

Assumptions about what an outboard engine can accomplish and what today's more environmentally-conscious world expects from an outboard, will begin to change forever. Evinrude E-TEC is a quieter, cleaner and extremely low maintenance engine that satisfies the requirements of Jean-Michel Cousteau of Ocean Futures Society and others whose sole purpose is to ensure a cleaner environment.

Designed to meet CARB 3-star emission standards, Evinrude E-TEC will optimize oil and gas consumption. The stratified combustion chamber creates 80 percent less carbon monoxide than a 4-stroke creates at idle.

The sealed fuel system minimizes evaporative emissions. The engines feature the E-TEC auto lube oiling system that eliminates the mixing of oil and fuel. Evinrude E-TEC engines also have a lower oil flow due to targeted oil delivery system and pass-through connecting rod lubrication.

With the on board monitoring system ensuring the exact precision use rate of E TEC oil, Evinrude E-TEC engines use approximately 50 percent less oil than traditional direct injection systems and 75 percent less than traditional 2-strokes*.

The Acoustic Story

To live up to its claim to be the next generation of engine, E-TEC owners will immediately notice the whisper-quiet operation and what Bombardier refers to as a "signature sound" when on power.

The unique application of a molded foam inner liner optimizes depth and coverage of the acoustic treatment in both the upper and lower motor covers. Evinrude E TEC includes an air silencer designed to reduce air-borne sound. It also improves sound quality through the inclusion of a Helmholtz resonator, which is located in the side branch intake and helps reduce sound from the engine.

Bombardier incorporated an improved piston design that decreases the "piston slap" sound. When some competitors' pistons slide up and down in the cylinder, they can make a slapping sound. Bombardier has enhanced the piston guidance in the cylinder to significantly reduce that sound.

Another sound contributor in previous generation outboard engines is in the
throttle plate. Evinrude E-TEC features an idle air bypass (intake side), which eliminates the need for relief holes in the throttle plate and also delays the throttle plate opening that results in a quieter idle and trolling speed. E-TEC also features enhanced idle relief (exhaust side) geometry for a pleasant idle sound.

Redefining "Low Maintenance"

The reliability of Bombardier-built engines is demonstrated with three-year, no scheduled maintenance on Evinrude E-TEC - the industry's most comprehensive warranty program. The on-board engine management module (EMM) means no dealer winterization, spring tune-up or scheduled maintenance for three years of normal recreational use. The digital diagnostic panel monitors the engine and user-friendly lights notify the owner of any system checks.

The Evinrude E-TEC low friction design provides boaters with enormous benefits: these engines employ no belts, powerhead gears, cams or mechanized oil pumps. Also, the oil doesn't need to be changed, providing added savings on expensive oil changes and filters. Oil changes on other technologies can cost several hundred dollars each year. That means that these weak points of traditional 4-strokes are eliminated.

Durability, Quality and Reliability

Evinrude E-TEC engines feature a "sure start system" designed to fire within one revolution, ensuring a quick start. The fully-stratified start up is controlled by the EMM onboard computer that eliminates the wetdown period.

Evinrude E-TEC parts demonstrate a high level of quality. With full magneto electronics, the E-TEC system can be started without a battery and eliminate worries of running the engine should a power failure occur. The beltless 25-amp charging system means that there are no moving parts to adjust. The flow-through cooling system and extra capacity water pump ensure the optimum engine temperature. The sealed fuel system is designed for long-term storage, as well as heavy-duty usage.

These smaller, lightweight engines - in the case of the 90-hp E-TEC, as much as
100 pounds lighter than traditional 4-strokes - feature "big motor" components.
Within the compact Evinrude E-TEC engines are many tough, oversized components for durability: rods, rings, pistons, bearing mounts, cylinders, heads, gear case, injectors, reeds, intake systems, fasteners and the cooling system. The pistons, made from special alloys, are nearly three times stronger than traditional pistons at operating temperature.

The Evinrude E-TEC full corrosion package features electro deposition paint, with epoxy high temperature paint on the exhaust components.

Breakthrough Styling That Works

Designed from the ground up at Bombardier, Evinrude E-TEC outboard engines incorporate new design features and sleek styling. The bold, new and unique face of the cover has a swept-back profile with a red three-dimensional beltline and a self-aligning hood for easy removal and replacement. No more wrestling matches. The double wall upper cowling also helps suppress engine sound better than before.

The E-TEC engines really showcase the design capabilities of Bombardier engineers and designers. This striking new design will apply across the entire Evinrude E-TEC horsepower range, giving boaters a really good-looking engine for all applications. And besides looking good, it makes it easier for boaters to access the engine.

E-TEC features a compact and lightweight design. Using state-of-the-art 3-D computer models, Bombardier specified "big motor" components to ensure best in class durability, quality and reliability in every engine.
