What is Evinrude E-TEC?

Evinrude E-TEC includes both new technologies and improvements to existing technologies. We've built these technologies onto existing and proven - durable, reliable platforms. For example, our 2-cylinder 40 through 60 horsepower Evinrude E-TEC outboards are built on the mid-section and gear case of the 55 horsepower Commercial series outboards. In fact, the Commercial outboards are the basis for the outboards the U.S. Navy Seal Teams and U.S. Marine Corps Recon Teams rely upon during their assigned missions. The 3-cylinder 75/90 horsepower Evinrude E-TEC outboards are built on the mid-section and gear case of the 60 degree V4.

What does E-TEC stand for?

E-TEC is not an acronym, it doesn't stand for anything. E-TEC is the name we have chosen to apply to this new technology.

Is Evinrude E-TEC a 2-Stroke or a 4-Stroke technology?

Evinrude E-TEC is the best of both technologies. It provides the quiet, efficiency and cleanliness many customers associate with the 4-stroke outboards, combined with the torque, throttle response, quick acceleration and raw power associated with the 2-stroke outboard. The technology is considered 2-Stroke, Direct Injection. Evinrude E-TEC in fact, has cleaner exhaust emissions than a 4-stroke, it produces 5 to 10 times less Carbon Monoxide (CO) while idling or trolling.

What is the new technology used on Evinrude E-TEC outboards?

Evinrude E-TEC uses several new technologies. The most obvious, when looking at an Evinrude E-TEC outboard, is the fuel injector. It is not a solenoid type injector, like the Evinrude DI models Bombardier began producing for the 2002 model year. This injector design requires less operating current to activate, meaning we are able to use smaller electronics which operate at cooler temperatures. Cooler running electronics equates to durability. The injector has fewer parts and requires fewer tight tolerances, which lowers manufacturing costs.

What about the not so obvious technology?

What's not obvious about Evinrude E-TEC is what's inside the engine block. Evinrude E-TEC incorporates pistons made from a new alloy, which was developed by NASA. This alloy has proven to be 2 to 3 times stronger at operating temperature than the aluminum alloys pistons are traditionally made with. The pistons used in the 40 through 60 and the 75/90 are what's known as "full-skirt" pistons. The internal design of the block (the intake, exhaust and transfer ports) doesn't require machining "port windows" into the piston. This combined with the new alloy, increase the piston strength and durability.

What else have you done to the internal engine components?

We still use the time-proven method of lost-foam casting our engine blocks, which are then CNC machined for accuracy. Chrome faced piston rings, Boron-Nitride Honed bores, micro-ground crankshafts and large over-sized bearings contribute to the low-friction design. The connecting rods are taken from the 60 degree engine family.

What about the rest of it? There has to be more than just a new fuel injector and engine block, right?

As stated earlier, there are improvements too. Just as the electronics in our home & office PC's have advanced and become smaller packages, so have the electronics (microprocessor) in our engine management system. The improvements Bombardier initiated to the Engine Management Module (EMM) beginning with 2002 production, such as a 30% thicker pc board and increased cooling for components, have been designed into the EMM for the Evinrude E-TEC outboards. Additionally, our Engineering Team has incorporated diagnostic LED's into the housing, allowing basic troubleshooting to be performed without diagnostic software. A flexible casing and 60% smaller size complete the package and provide a clean, state of the art, under-hood appearance.

What have you done to make the engine so quiet?

Our Engineers designed a new air intake system for these engines. The intake system serves to quiet engine noise. An idle air by-pass tube supplies air to the crankcase at low rpm. There are no holes machined into the throttle plates, therefore no whistle sound at idle. Innovative baffling in the air silencer box cancels resonant noises. Unlike other manufacturers' outboards, there's no distinctive "pucka-pucka-pucka" sound of an air compressor, or any belt whine, or any cam chain noise - we don't use them.

How much do the E-TEC outboards weigh?

The 40/50/60 models are available only in a 20 inch shaft version which weighs 240 pounds. The 75/90 models are available in both a 20 inch shaft version which weighs 320 pounds and a 25 inch shaft version which weighs 335 pounds. The 200 through 250 models are available in a 20 inch shaft version which weighs 516 pounds, a 25 inch shaft version which weighs 524 pounds and a 30 inch shaft version which weighs 530 pounds.

What about battery charging?

On 40 through 90 models, the system will supply 3 to 5 amps at idle speed and can provide up to 25 amps at higher rpm. On the V6 models, the system provides 10 amps at idle and up to 50 amps at higher rpm.

Do I need a battery to run a rope start Evinrude E-TEC outboard?

No. A battery is not required to run the rope start models. However, if you have electrical accessories you want to operate and would like to take advantage of the charging system, the capability is already there. In the event of a battery failure with an electric start model, the engine can be rope started and run without the battery.

Earlier I read this engine uses an electric fuel pump. It also has an EMM, which is basically a computer. How is such an electrically dependant motor able to start and run without a battery?

Simply put, just like any rope start motor, it generates its own electricity. To make a comparison, lets discuss the electrical system of a carbureted 25 horsepower 2-stroke for a moment. The basic system design has been around for over 25 years. Underneath its flywheel is a single charge coil, which produces the voltage to operate the ignition system. There's also a very small stator to provide electrical power for AC Lighting or optional battery charging and, there's a sensor coil which provides the ignition timing. Since Evinrude E-TEC doesn't need a charge coil or a sensor coil (because these functions are controlled by the EMM), a full-diameter stator which uses more windings compared to the 25 model above, is employed. Powerful rare earth magnets are used on the flywheel and, by adapting our patented switching stator technology, the stator is able to generate more current at lower rpm. The voltage required to turn on and "boot up" the EMM is delivered in a few milli-seconds. By integrating pulse width modulation technology (which has been used on electric trolling motors for decades), we are able to power up the electric fuel pump and not put an excessive demand on the electrical system while starting the motor. The EMM and fuel pump power up take place in the first third of a revolution of the flywheel. The EMM then determines crankshaft position via a sensor which "reads" the flywheel encoder vanes - all of this occurs within the first complete flywheel revolution. This leaves plenty of rope to pull and provides ample voltage to subsequently fire the injectors and ignition and get the engine running.

I read elsewhere on your web site Evinrude E-TEC engines can run up to 50 hours without needing to add oil to the reservoir. How do you define that 50 hour run period?

This is based on ICOMIA studies which have found the average recreational user runs their engine 50 hours per year and, for each hour of run time, they run their engine: ·       24 minutes @ idle ·       15 minutes @ 40% throttle ·       9 minutes @ 60% throttle ·       8.5 minutes @ 80% throttle ·       3.5 minutes @ full throttle Therefore, if you idle or troll more than this, you may use less oil, or, if you run full throttle more than this, you may use more oil.

What propellers do you offer for the Evinrude E-TEC outboards?

The Evinrude E-TEC outboards accept our existing line of propellers. We offer a multitude of different props in both aluminum and stainless steel. The stainless prop line includes the 3-blade SST 2 (painted), the 3-blade Viper (polished), the hi-performance Raker (polished) and the 4-blade Cyclone (polished) and Renegade Bass (polished).

How does the Auto-Winterization feature work?

When the Auto-Winterization feature is activated, the EMM rapidly cycles the oil injector to "fogs" the engine. When the winterize cycle is complete (about 1 minute), it will automatically shut the engine off. Once the engine has turned off, turn off the key switch (if equipped), remove the engine from the water or from the flushing device and allow the water to drain from the engine. Your Evinrude E-TEC is ready to be placed into storage. The only additional item we recommend is to remove the propeller and inspect the propshaft and seal to ensure there is no fishing line wrapped around it.


What kind of oil can I use for my Evinrude Etec Engine?

XD30, XD50 and XD100 oil is recommended for all 1993 and newer motors.

What is the fuel/oil mix for my motor?

The following is generally true: 1958 and prior used 20:1, 1959 thru 1963 used 24:1, 1964 and newer use 50:1. High performance usage (racing) requires a ratio of 25:1. New engine break-in (not DI) requires 25:1.

I live in an area where they only sell oxygenated fuels. Will this hurt my motor?

Oxygenated fuels should not hurt motors. Motors can tolerate up to 10% alcohol in fuels, which is the maximum allowed by law in the United States.

What grade of fuel should I use in my motor?

Current recommendations are to use a minimum of 87 octane, 89 octane is preferred. There is no additional benefit from using higher-octane fuels, in fact they may cause hard starting conditions in hot weather. If you have an older motor and the owner's manual requires premium fuel, here's why: When these were built, the best oil available was TCW-2 rated, and did not contain the additive package (detergents, carbon preservatives, etc.) which our current oils (XD-30, XD-50 and XD-100) contain today. In that era, premium fuel contained the additive package that helped prevent the formation of internal engine deposits. That's why premium fuels were preferred at the time. Ultimately, in the late 90's the federal government mandated fuel refiners to use the same additive package in all grades of fuel and the premium fuel requirement was dropped.

Can I use synthetic oil my OMC Cobra engine?

OMC Cobra's must use straight 30W oils. You cannot use multi-viscosity oil. The additives that are put in multi-viscosity oils cause the oil to break down too fast. This will cause the oil to lose its lubricity characteristics. Remember, a stern drive engine application is much different than a car or truck - the stern drive engine normally sustains a higher running rpm for a longer period of time than a car or truck ( most cars or trucks cruise 2500 rpm's or less, where a stern drive will run 4000 rpm or more ). Using a synthetic oil is acceptable if a straight 30W cannot be found. The change interval remains every 50 hours! Therefore, given the higher cost of synthetics, this doesn't make them cost effective for use by most boaters.

I have some oil that has been sitting on the shelf for a few years. Is it any good? Can I still use it?

Yes, just shake it up and it will be fine (it may need to be room temperature).

I have a lot of TCW-2 oil. Can I still use it in my motor?

Yes, as long as it's a 1992 or older motor. You may want to use Carbon Guard to minimize the formation of carbon deposits in the engine. Using TCW-2 oil in a motor that requires TCW-3 oil will void your warranty, should an oil related failure occur.

Why are your TCW-3 oils different colors?

Our oil comes from different suppliers. Each uses a different dye (for identification purposes), but the oils are formulated exactly the same.

What type of gearcase oil should I use? How much does it hold?

Refer to your owner's manual.


Where can I find service literature such as service manuals, owners manuals or parts books for older Evinrude® and outboards?

Evinrude® Genuine Parts stocks parts books, service manuals and operators manuals for 1997 and newer products. They may be ordered through your local dealer. For 1996 and older models, service literature may be available from: Ken Cook Company, 9929 West Silver Spring Drive, Milwaukee, WI 53225, 414-466-6060. www.outboardbooks.com. We suggest you have the model number of your product handy if it's available. While Ken Cook may not have every manual for every motor, they do have a wide selection of material for many model years.

What year or horsepower is my motor/boat/snowmobile?

See your dealer and have them refer to the current Model Year Reference Guide.

I would like to get an accessory kit for my motor. Do you offer one?

A kit may be listed in the Dealer Parts & Accessories (P & A) Catalog, or sometimes a specific kit may only be listed in the individual engine parts catalog. See your dealer.

What size of prop should I use on my motor?

There isn’t one propeller that is right for any given motor. Too many variables effect performance: You need to know what rpm the engine is running at wide-open-throttle. From there, use this rule of thumb to determine which pitch prop to select: 1 inch of pitch changes engine rpm approximately 250 rpm. Increasing pitch, decreases rpm. Decreasing pitch increases rpm.

I need to repaint my engine, is paint (still) available?

See your dealer.

Where can I get spare keys for my motor?

Keys can be ordered through any Evinrude/ Johnson dealer.



Eliminating model year designations will not affect a consumer's warranty coverage. Warranty coverage will begin at the time an Evinrude outboard engine is warranty registered and according to the date of delivery that is referenced on the engine registration. For example, a 50 HP Evinrude E-TEC engine that is sold and warranty registered in May of 2012 will have a three-year limited, non-declining warranty, regardless of when the engine was manufactured. Therefore, eliminating model year will not have any impact on a consumer's warranty coverage. For more details on warranty coverage, please refer to your factory warranty statement.

Resale or Trade-In Value

Boat package values are established by organizations like NADA (National Automobile Dealers Association) based upon the model year of the boat. This is standard practice for automobiles, stern drive boat packages and many other applications since the engine is viewed as a component of the entire boat package. With boat values being based completely on the boat's model year, the elimination of model year on Evinrude outboard engines will not affect resale value. When an engine is traded in, the hours of use will determine the trade in value, as hours of use is the marine equivalent to mileage on an automobile.


BRP will supply an MSO (Manufacturer's Statement of Origin) for Evinrude outboard engines that are purchased by a dealer in states that require MSOs for titling purposes. Currently, there are six states that require outboard engines to be titled, including: Missouri, Ohio, Oklahoma, South Carolina, Texas and Utah. The MSO will no longer indicate a model year however; it will display the date the engine was manufactured (i.e. May 2012).

Serial Number Label

Evinrude outboard engines have a serial number label that is located on the transom bracket. Serial number labels will reference the date of manufacture for the engine by providing visibility of the month and year the engine was produced. For example, if an engine was manufactured in May of 2012, the serial number label will reflect 05/2012 directly below where the serial number is indicated.

Date of Manufacture

When a significant product change occurs (i.e. when a new model is introduced that replaces a prior version), the model designation will change as needed. By utilizing this process, models with the same code are physically identical, regardless of when they were built. To view the date of manufacture, reference the serial number label that is located on the engine (see example above). An authorized Evinrude dealer can help you identify the date of manufacture on the engine(s). This is also of particular importance if you are repowering a boat with dual or triple engine applications.

I'm winterizing my motor and have some questions about what is written in the book.

Contact your dealer.

I live in an area where they only sell oxygenated fuels. Will this hurt my motor?

Oxygenated fuels should not hurt motors. Motors can tolerate up to 10% alcohol in fuels.


I need to have my trolling motor repaired. Can I send it to the factory?

No. We do not perform any repairs. Any authorized Evinrude repair facility should be able to perform the repairs.
