Default Edumacate me on etecs

Can someone give me a quick version of how an etec works? I saw the comparison thread going and it got my interest. I assume it's a 2 stroke with different technology that makes it cleaner and quieter and requires less maintenance than a 4stroke?. There's a boat fairly local that has a 2011 90 etec that I've been avoiding cause I want a 115 4stroke so I wondered. Also seller says it a "commercial" etec. Is there such a thing? Thanks!

The E-Tec is a 2 stroke that employs some modern direct fuel injection technology or what's known as DFI. The E-Tec also has an advanced oiling system that allows it to use less oil than other 2 strokes and a lot less oil than the traditional carbed 2 stroke.

The engine will actually reuse the oil a few times at low speeds, this is what makes them so oil efficient at trolling and idle speeds.

The DFI system is controlled by the EMM or engine computer. Each cylinder has its own fuel injector which eliminates the high pressure fuel system or fuel rail found on other fuel injected engines. Each injector is controlled by the computer and will deliver only enough fuel needed for the current throttle position and engine load. The EMM also controls oil delivery based on engine load. The injectors also stratify the fuel into an ultra fine mist for which minimizes unburned fuel making it out the exhaust. The unburned fuel out the exhaust is what made the traditional 2 stroke so bad on gas and emissions.

There is such a thing as a commercial model, but I'm not sure if these engines meet the EPA standards.

I love my Etec. Runs very strong, good mileage. If the boat is commercial that may reduce the warranty on the motor. I don't think they have a "commercial" motor designation.
Check at etecownersgroup.com Lots of good info there, represented by BRP dealers, service techs and enthusiasts.

As long as they work and run correctly, you will like them. As long as you don't do LONG distances where you burn a ton of fuel, you'll like them. As long as you have a knowledgable dealer NEARBY, you'll like them.

Or buy a conventional 4 stroke. They really are quite reliable. Long distance requiring alot of gas doesn't mean buying and adding expensive oil.

Around here, with very little support, an issue with one is a Kiss of Death.

I would just do the 4 stroke.

scarabchris's description is right on. Basically it's a very sophisticated version of a 2 stroke and bears very little resemblance to older 2 strokes and other than adding oil in a remote tank you wouldn't notice any difference vs a 4 stroke. Maintenance intervals are longer and the motors are simpler, some of the models self winterize, which is a very cool feature. Good dealer support is a must as you need the right software etc to work on them, but they are on average very reliable and on par or better than the other major motor brands out there. You'll get folks with religious opinions about them for some reason, and there is likely some effect on resale because the average buyer associates 2 stroke with old smelly motors.... that should help a small bit if you're buying used.

I think you misunderstood what the OP wanted which was education on the workings of an Etec not the workings of an Etec basher...what IS it with you people?

;?

Could you expand upon that comment?

I was under the impression that outboards in general "self winterize", with the possible
caution of changing the lower unit lube in case some water has migrated there during the warm season.

I'm reminded of the dozens of skiffs I see at Stonington, Maine, that are left in the water year-round...all with small to medium size 4-stroke outboards on them. Tilt them up, and they are winterized, apparently. These skiffs are tenders for moored lobster boats, and most show lots of deferred-maintenance, or no maintenance, but that may just be cosmetics.

4 stroke never need any maintance, never break down, never any fuel problems , oil changes are allways cheap, and convenient to do while on that long trip. They use cheap oil. Can run on anything. As the saying goes above , as long as they work and run correctly, you will like them.;?

Both 4 stroke and 2 stroke are very reliable. I run 2 boats. Etec, verado. Happy with both. Would not hesitate to buy either. Sold 4 stroke yam. Also reliable. Why waste your time talking out of your ..., where i live support for all brands avail. If no dealer available for any brand where I live then I probably would pass on that brand.

I just bought a 2011 Etech 250.....love it, however, I have only been out two times.

Bottom line some will bash others will love.... the fact is all new outboards are great engines. Go with the best service in your area and dont look back.

Scarab Chris has a very good overview of the e-tec with one exception. Where you see fuel injected cross that out and put direct injection ...2 different things.You do have e-tec haters out there for some reason and most have never owned or even been in a boat powered by one.I have 2 200 ho e-tecs with over 2000 hrs on them and never a problem.

I had it worded correctly. I labeled direct injection as direct fuel injection or DFI...same thing.

Sure. To be more specific they self fog, and of course self drain like all outboards. The self fog feature basically goes through some sequence where it runs and adds extra oil and fogs the motor for you. To initiate you just do something specific with the throttle (have to read the manual because I never remember) and it runs for a few minutes and then shuts off when it's fogged. I believe it's only available on the bigger engines, but I'm not sure what the cutoff is (maybe around 100?). Unfortunately you still have to do the lower unit oil, but they recommend 300 hours or 3 years for that and so you just need to check for water intrusion if it's not due for the service.

He had it right. It is fuel injection. As in "direct" fuel injection.

Not to be confused with throttle body fuel injection or port fuel injection.

Not to be confused with mechanical constant flow fuel injection.

But, it is fuel injection.

Some four stroke motors (no outboards yet that I know of) use direct fuel injection technology also.

So when I take my 115 e-tec in for winterizing what exactly are they charging me for ? Thanks

You can winterize it yourself. I am not sure of the exact procedure as we have year round boating here but I saw a video on you tube. Its nothing more than a turn of the key and pushing the throttle in a certain sequence.

I guess if you take it in to get winterized the mechanic will only be able to charge you for labor. It shouldn't take him (or you) more than 5 minutes. But most shops have a one hour minimum.

Kone, let's add a few details about the E-Tec system. I'm on my second 90 and have run E-Tec 90's since they first came to south Florida.... The heart of the system is a unique way of powering their fuel injectors (most DFI systems use a mechanical means of sending the fuel to the cylinders, the E-Tec uses purely electronic means). Each injector sits in a metal cone with a disc at the back that functions much the same as a stereo speaker... a pulse of electricity causes it to flex and send a precisely metered amount of fuel to the cylinder as needed. Internally the motor actually operates on 48volts, instead of 12 (the charging system still charges at 12...). And yes, there's no break-in period on an E-Tec just run it the moment you're on the water (it will automatically double oil the first 10 hours...). Along with a few other features there's one other small item... if you ever have to.. the 90 pull starts easier than most lawn mowers (one of those, ask me how I know deals since I've done that with two different motors). One other small point... many modern motors have had terrible difficulties with ethanol blended fuels.... The E-Tec system is much less vulnerable to that kind of problem.

Now for a few other considerations if you're thinking about one... These motors need competent, factory trained techs so you're going to want an authorized service center convenient to where you'll have the boat... Make sure that they have a good reputation before you need them.... Do not under any circumstances allow someone not factory trained any where near an E-Tec except for work on the lower unit (lower units aren't much different now than they ever were). That particular model motor will come from the factory set to operate with XD50 oil (semi-synthetic blend, for standard 50-1 oiling) it will also run with XD30 (the same as TCW3 oil) if necessary but stick with the XD50... It can be re-set by your service center to operate on XD100 oil (fully synthetic, which will allow it to run at roughly 87-1 oiling). The XD100 is a bit more expensive but you use less of it... The only downside to the higher setting is that once it's done you must use XD100 oil - nothing else. The motor can always be re-set to the XD50 setting, though...

Can't comment about the one you're looking at being a "commercial model" since I've never heard of one (and both of my motors were purchased under the guide program for commercial service). To find out about the warranty on that motor just copy down the model and serial numbers (on the motor bracket easily visible) and have your local BRP service center check it out with the factory... Both of my motors came with a three year warranty which was fully transferrable to the next owner. Since my current motor is now five years old and has more than 2100 hours on it I'm well out of warranty and hope that they'll allow me back on the guide program for my next motor...

For anyone that needs to know... the only benefit of the guide program is a reduced intial purchase price. After that you stand in line and pay for everything you get - no freebies... I'm probably a bit prejudiced toward Evinrude (whether OMC or BRP is building them) since I've never had anything else all the way back to 1973... I make long runs in bad places (Everglades National Park, mostly) where no one will even come looking for me and my customers until a day later if I break down.... My average run is between 60 and 75 miles each day, round trip in brackish or salt water jungle areas. I've never had a better motor than the 90, and will buy another one as soon as I'm able...

There's a bunch of stuff they may do around maintenance. When I had a shop do mine they just used the engine's built in mechanism to fog and then charged me for labor to grease the lube points and I had them do the lower unit oil because of the number of hours I had, even though it's earlier than required. Most shops will also change the fuel filter / water separator on the engine and on the boat. They'll probably stabilize the fuel too. With all that it was cheaper than having my old 4 stroke done, I think I paid around $200 for my 200HP...

I can only speak for myself, but personally, I would not consider a boat with an E-Tec. I've seen real world fuel burn #'s on them and am not impressed. That and the $70/gal oil our local dealer recommends, run at the 50:1 ratio makes it a poor choice.

I don't know of anyone that is disatisfied with their 4 stroke Yamaha's. I cannot say that about the E-Tecs at my marina and among my social circle.

Before I get flamed, I'm not speaking for everyone, or every E-Tec, just what I've experienced the past 5 years.

Holy cow, $70 / gallon? No wonder they're unhappy. Going rate is 30 - 40 depending on where you get it from. I order in bulk online and pay a bit over 30 per gallon including shipping.
