Evinrude e-tec 90 HP: Owners/ Users -How are they working out so far? Just looking for some up-dated info. Any reason not to buy one for a 16 ft Nauset/ Eastport/ Sakonnet? Thank You.

Nothing surprising about a blown powerhead on an E-TEC 90, or a Merc. It can happen with any brand of motor and be caused by a manufacturing defect or owner abuse. We see a lot of them in the shop and very few are manufacturing defects, Merc or J&E.

[Removed articles complaining about the search engine and lack of information on the website re recent E-TEC experiences. Apparently all the good information on E-TEC is elsewhere, as provided in links above.]

Opps--Dick--I was editing the thread while you posted. Yes, I guess you can blow up an engine even if it is just a few weeks old!

I really do like the look of those E-TEC engines under the cowling. They just have an appearance of being well designed and thought out. Some engines have a spaghetti bowl of hoses running hither and yon under the cowling, and you wonder what all that plumbing is there for! The E-TEC engines look simple and organized in comparison.

I guess all the E-TEC guys are out boating and too busy to follow up with postings.

A report from March, 2004:

I'm seriously considering an E-TEC 90 for the Eastport I bought last week. Man, this would be one sweet motor for that!

Here is another report on E-TEC results, just posted a few days ago:

Another thread of interesting comments on the E-TEC from March:

In total there are about 150 message threads with articles on E-TEC engines available for review here on the website.

Sorry for the delay in updating, I'm getting married in 10 days, and have been recovering from my 4-day bachlor party for the last 3 days.

I purchased a 2004 90hp E-TEC. It was #7 off the production line. I have 4-inch CMC set back brackets, with the cavitation plate 3-inches up from the lowest transom point. After some tachometer problems, an ECM software upgrade, and several different propellers, I think I have found the correct set-up, and am quite pleased with the engine's performance. (I have a possible ECM upgrade correction still pending with Bombardier, so my propeller size may change back to a 13.25 x 17.)

I am currently running a 13.25 x 15 stainless steel Stiletto Advantage propeller. 5500 maximum RPM at 42.5 MPH, with a light load. Initially, there was some significant vibration at 900-1100 RPM, but this has all but gone away. The smaller propeller seems to have helped a lot. This weekend I saw 4300 RPM, with 5 big guys and a Lab, at 6200 feet elevation.

The engine runs flawlessly, starts on the first crank every time, is quiet, smokeless, and very, very fuel-efficient. Oil consumption is almost undetectable. I was on the fence between a 70hp Johnson 4-stroke and the 90hp Evinrude E-TEC when I made the purchase. The deciding factor was the light weight and additional 20hp. As I sit here today, I would still be on the fence. I love my E-TEC, but finding the correct set-up has been a bit of a hassle. I think I have it for now, so I am very satisfied with the engine...and I still have 2 years and 6 months until my first scheduled maintenance!

Hello Ratherwhalering,

Thanks for the update...much appreciated...

I'm curious about your observation that the vibration at low RPM has gone away on your E-Tec 90. As you may recall, I observed a similar vibration at idle speed (don't remember the RPM range exactly, but probably similar) with my E-Tec 50 on my 15 Sport. It was easy to detect because my GPS unit would shake (and the power/DSC plug would fall out) and my front thwart seat and bow hatch would vibrate.

But I didn't notice this vibration when I had the boat out Sunday. In fact, I did notice *not* noticing it. Either the vibration has gone away or it has diminished on my 50hp E-Tec.

Did your vibration go away on its own, or did its disappearance have anything to do with you trying different props and getting the software upgrade?

I'm not sure that I've zeroed in own my optimal setup (prop, engine height, etc.) because I just haven't had time to fiddle with it like I'd like. When I've had the boat in the water, my wife and baby have been with me, and so there's no opportunity for swapping props (I have three now!), running full throttle or doing speed tests in two directions.

But it's curious that my vibration has diminished.

Congrats on the nuptials!

Its still there, just hardly noticeable. I think that I'm the only one who actually still notices it. It diminished with the ECM upgrade, then even more with the smaller prop. Thanks for the nuptual support, I need it after the bachlor party!

OK, thanks for the information and the observation. I will pay more attention to mine this weekend.

Mobey, I don't have an E-Tec 90 or the same hull as you, but based on my experience I can think of no reason not to go with that combination. The 50 is as heavy as a four-stroke 50, which gave me pause for extra consideration before deciding to go with the E-Tec anyway on my classic 15 hull. But the E-Tec 90 is a lighter alternative to the four-strokes in that size, I believe, an probably ideal for your application. Good luck whatever you decide. Maybe some other E-Tec early adopters may chime in sooner or later.

I have a chance to sea trial / test drive E-Tech 90 this weekend with Lockeman's Hardware and Boats, the Evinrude Dealer in Detroit that does all the work on my 1982 Evinrude 90. They speak very highly of them. I also looked at the E-Tech 70 (or was it a 75) at Pointeau Baril Station, Ontario while on the BWGLCC Rendezvous, that one was amazing quick start / quiet operation, although I didn't do Sea Trial. I'm thinking of re-powering my 1982 Montauk next summer. Lockemans stated they could use my current Morse control so that would be some savings for me....I'll post comments after the Sea Trial this weekend...
