Evinrude E-TEC™ 90-HP Engine

I got my first look at an Evinrude brand E-TEC™ engine. It was the first unit in Utah at a dealer about 100 miles north of me. They are a Yamaha and Evinrude dealer and I could tell Evinrude has been on the back burner for them for a long while.
I could tell they were excited ( but guarded) about this. They typically have been installing Yamaha 4-stroke engines and the loss of horsepower up here in at altitude plus the weight factor as been a problem with some customers.
They started it up in the back warehouse on a hose and I was impressed by the lack of noise by the engine running out of water campared to a typical two stroke. Absoutely no smoke at any RPM range this was in a building where it would be noticable. We compared it to a two stroke 1999 Yamaha 75-horse which was much louder.
I pulled off the cowling, very neat, less complex looking that a comparable Optimax. Very good looking motor.
No startup smoke, no break in period, 3 year warranty with the option of 7 year which I didn't get all the details on. It is available in dark or white, will adapt up to most older omc prerigs as far as shift throttle goes. Complies with all emissions current and comming
Not a detailed lake test with a foot of snow on the ground, but my first impressions were very favorable

Now all we have to do is wait for the Big Ones to be released..
I am curious about this..
Where does that leave the 115hp, 135hp, and 150hp?
I haven't seen any reports on these larger engines, but I think we can assume the 115hp is going to be 4 cylinder otherwise it would be out "Now" along with the 75hp and the 90hp...
Is there going to be a 135hp?
I am very curious as to what engines are going to be 4 cylinder.. Even if the 150hp is a 6 cylinder, I would consider a 135hp (if it were 4 cylinder) for the back of my 18... Obviously less weight then a 6 cylinder and probably not any less power then we are running now with our older 150hp OMC's.....
Just a thought,

I was wondering that as well, 4 or 6, inline or V. We are on the eve of Mercury releasing their new line and from posts here, it looks like inline is popular.
Yamaha new 150 4 stroke is a 4-in-line and it will be interesting to see what Evinrude does with their E-TEC™.
I have been looking for a quieter cleaner repower and I like the fact that 4 strokes do that well. I am not sure that up here at altitude (4500-7000ft) it would work here well, especially with a kicker 4 stroke on the back.
I have heard (haven't confirmed) that at 5000 ft, a solid 25 % of horsepower is lost due to oxygen content in the air. DFI, EFI, doesn't make up the difference. When I take my Whaler to a local popular lake up here (Flaming George) at 7700 ft I run a 18 pitch OMC raker and can't get over 35 mph and barly get 4000 rpms. When I took my boat to Lake Mead at Las Vegas last summer (about 1200 ft above sea level) my boat flies in comparison with that same prop at 44-46 mph and I can reach 5000 rpms easily.
Max hp with 4 strokes up here really struggle and aren't enough. Weight on the transom is huge and Optimax has expoded in our local market because of less weight and cleaner burning.
I hope Evinrude will do the same. I have been brand loyal to that company since my childhood and my Dad used to take me fishing in a rental boat and bring his 25 hp Evinrude (1963) I would rather have some compatibility in a engine change out rather than lose all rigging.
My question is will they do the same as Merc/Yamaha and Honda did with 4 strokes? Skip the 150/175 class for a few years and go straight for the 200-225 class and later come back. If so, it could be a while before we get another good option for our 18s ORs.

Only speculation here, no hard facts.
Because the combustion chambers of the current 40 through 90 HP E-TEC™ engines share the same dimensions (bore & stroke) as the current 100 through 175 HP engines, I think that the E-TEC™ versions of the 100 through 175 HP engines will built on the same blocks as the current DI motors are. If my speculation is correct the current 60 degree V4 will be used for the 100 and 115 HP and the current 60 degree block V6 will be used for the 135, 150 and 175 HP engines. My speculation is primarily based on not exceeding current horsepower to cubic inch ratios. I'm told that the 60 degree V blocks have a somewhat restrictive exhaust system that might prevent them from reliably and cost effectively getting an honest 135 HP out of the V4 block. Also, Evinrude usually under rates output a little.
As far as idle sound of the direct injected Evinrude 2-strokes go, they are much quieter than their carburated counterparts. When I flushed my Evinrude 225 Fichts on ear muffs for the first time I couldn't believe how quiet they were. The other thing that was very noticibly missing was oil smoke.

You are the guy who should wait for the Mercury X engine if you can. You do lose 4 % of your power per thousand feet. Nothing, other than pressurizing the air intake with a supercharger or turbo will change that. Jets in your carb help little. They can help, in that with a rich mixture at high altitude you may be be losing more than 4 % and by leaning the fuel to a proper ratio you may lose only 4 %

Sterline, I certainly wouldn't be running that 18p prop up there & only getting 4,000 rpms.
The only thing is, you would need to drop about 12" of pitch & now your looking at a 6p prop that wouldn't give you 20 mph 5,5oo rpms so your up the creek as long as your up the hill.
As far as jets & different plugs go up high, it helps, but your still not going to get whatever hp your engine is rated at.

From the currently available information, my understanding is the E-TEC™ engines are only available up to 90-HP. Exactly what technology the larger horsepower engines in the Evinrude line are using is not clear. Perhaps it is the Ficht injection, minus the name branding.

I think you are correct. From my visit with the dealer, the new E-Tech motors are only up to 90 horses. Everything above that point is the existing Ficht technology which they won't carry. They have dropped the name off the cowlings. They just use the word " direct inject".
I suppose that is because the Ficht name has hurt them, even with the improvements made and Evinrude doesn't want that decal anywhere.
Our dealer said he thinks 150s-225s are a year away or more.
I looked carefully under the cowling at the 90 hp E-tech and compared it to a 2 year old ficht on a bass boat in the back of the shop. They looked totally different, from the block casting, wiring, coils etc. Totally different. The castings on the gearcase I am quite sure, were different, everything looked different. I don't think Evinrude/Bomb is using any old parts from the bins. It appears to be a complete new start.
I directly asked the question, is E-tech a warmed over version of Ficht. The answer was "absoutely not" He showed me a few of the differences I have mentioned and then showed software differences on the screen. They had a tough experience with Ficht and would not have started again if it was only a warmed over, slightly improved menu.

There is an illustrated discussion of what makes an E-TEC an E-TEC at http://continuouswave.com/whaler/reference/IAME44-1_e-tec.pdf . One of the first sets of pictures shows the difference between the FICHT and E-TEC injectors.

Strangely enough, I saw a white Evinrude 90 E-Tec on display at the baggage terminal of Southwest Airlines at Ft Lauderdale airport a few weeks ago. I've got to say, it's a nice looking package, and so far the lightest weight clean 90 on the market. If it puts out a true 90HP and is not over-rated, it should be popular and give the others a run for their money weight/size wise. If it's not too strong, then it will be less successful.
Since it weighs exactly the same as my Mercury in-line 6 115's, a pair of these could be nice on an 18 Outrage.
