etech 90 - so wazzup?

[matt_unique]

The National Park outfitted two of their four vessels with brand new Etec 90's this year (twin engines on each vessel). Our older engines are 4 stroke Merc 90's.

Based on my experience with them over the course of this season I prefer the Merc's. Our Etec's definitely smell like 2 strokes and smoke more. Once warmed up I don't notice the smoke but the smell remains. Oddly, the Etec's vibrate a lot more than the Merc's. The Merc's have appreciably more low end torque. The Etec's have a nice power curve from about 2500-4500 and they are certainly smaller and lighter. I realize there could be several factors including props and they way they are setup and such but without knowing those details I prefer the 4-stroke Merc.

I have been happy so far with my Suzuki's on Napoleon. I can plane off with one engine and they are nearly silent runners.

I don't think any of the above are bad engines, just some nuances I have observed.

you peeps are wonderful, i am not worthy but the humiliation will be good for me im a way different mon that i once was, i was once too motivated with pride, which always goes hand in hand with fear, and then things get distorted im sure we all BTDT right anyway, your really lighten a fire under my LOL and it is going to be sumpthin i will not forget this summer a cupla c-brats got me drunk in the harbor! thier hospitality really made my day - i only hope i was not too much of a dissapointment lol really, i might be far different than ya'll might be expecting, i tend to be far better in print than in reality i guess.

OK, thanks for all the input again, you gize i treasure every single post!

in answer to a new long block; that is probably what i was really going to do in the end, i don;t think you can top what i already have anyway.

i found a few rebuild places on the web, and later i found a boaters forum somewhere that told horror stories of them so called rebuilds! then i thought about asking here of any good outfits that do long block exchanges ....

right now i think im going to bite the bullet and just do what i really want to do - - - - - JET! not just to be a hotshot c-dory (LOL ) but to be able to expore more country with far less stress maybe.

i often anchor in places where the prop drags on the bottom and thumps rocks at night when i forget to tilt, also a jet can give you the option of night running. And peace of mind, to a certain extent, in overall navigation. The new Merc sport jet changed everything! so lets hope i can actualy pull this off!

I think i might just do this in stages, so we all can learn

like just cut the floor and transom, pop er in and go like hell! if she cavitates to much, no biggy, just do adaptations to that easy to work on old classic. I can't wait to get started

Greg-

Nice to see you back and in such good spirits!

(And somewhat CRAZY, as always!)

Your Merc Jet 200 sounds interesting!

Have you considered how the boat will steer and maneuver at low speeds with the jet?

That's always been one of the chief drawbacks of jets, IMHO.

I'll see ya' in Seattle in january!

Joe.

Greg, are you sure when you hit the bar that the change in speed/torque didn't just slip your timing belt a notch or two. I'd check that if you already haven't. It'll screw up the compression real fast -- maybe you can get lucky...Digger

Hi,
Why not just fix what you have. Certainly Yamaha sells replacement rings etc. A 200 hp jet? Better buy stock in Exxon.

Greg – thank you for becoming involved in this group again – welcome back.

I wish I could help you with your decision about the E-Tech. I have a Honda on my 18’-16 C-Dory and am very happy with it. On our new boat the Marinaut 215 we put the 90 E-Tech on it and have just run some preliminary test with it. I am impressed with what little testing we have done with it. The only thing I have noticed that I would call a negative is there is a vibration at about 1200 rpm. If I increase the rpm’s above 1700 then bring it back down to 1200 rpm, most of the time it gets rid of the vibration.

The E-Tech seems to be a good strong performing engine. I believe it is quieter than my Honda. The biggest plus for me is the lighter weight and time between service intervals, but I would not hesitate using one of the other major outboard manufacturers.

cheers peeps im glad the site never stopped, its about the only fellowship i actually get living in wrangell :0\ but that is my own doing, i tend to be a hermit in real life, plus i been bizy inventin again when i got my container shop fired up.

if we get to the show, i at least have a CD with pix to show my biggest and best product-to-be ... its been getting less and less experimental and more real! maybe we show up in it.

the bigest problem is of course money right now, all post are actualy still helping me decide - i could change my mind again for the next few years it might just come down to a rebuild - so if anyone knows of a trust worthy rebuilder, do share! i need to decide on that before i tear into it myself. It's debt i fear the most in this! have not known debt since i was a teen and it never happened again in my life, so there we are - tmi again - lol

OK, the slow-speed maneuvering change is ok, it;s the noise that i don't want, need to check into this more, i was hoping it might not make huge noise that outboard jets do? i do like the sound of 2 stroke outboards and i also miss that good old "2-stroke-cologhn" on a boat you only get a whiff now and then, on snowmachines however- the smell saturated everything.

the 200 Merc uses less fuel than a much smaller 4 stroke outboard equiped with a jet, this tells me i might get as good as 5 mpg again? but i don't like the big cost of 2-stroke oil either, it all depends on oil consumption - i am thinkin pushing a c-dory clasic, the engine is going to be using a minimum - its like the faster you go the more the oil-ratio increases right? i think that's how it works, but im rusty on what is up in engines these days - have not needed one in the last decade

i did consider maybe the cams slipped, but the thing will fog an entire bay when you check the blow-by tube - it also puffs, telling me that at least one cylinder is damaged - i was running 40 wt jimmy oil just to get one more trip in this August! LOL on a 2-hunerd mile trip i went through 4 gallons of oil!

Dave, is the etech quieter than the Honda cuz it's new and the Honda a little tired?

our dealer here tells me if i went Merc 2-stroke outboard, id be louder than a 4 stroke.... any 4 stroke so i take it etechs are a stand-out in comparison with the other modern 2 -stokes? im really bummed to hear such etech bashing up here, some really surprising stories that i don't believe - i mean how come they still crank them out if its all true?

The big 125 3-holer Merc 2-stroke has got my attention to!, along with that new 4-holer Tohatsu! but i really still want to do the sport jet 200

thanks again for the post fellas - im out - ttfn - yep still crazy mon

Greg,
I believe the extra noise from a jet pump comes from where the exhaust is expelled from the motor. With a prop, it is deep under the water in the center of the prop. With a jet, it is in the jet of water at the surface.

ok - decision made

going to downsize - i think the future of gas prices demands this

also going to hack some lard off my both boat and mine

going with the new Yamaha 70! and also taking off my 8hp hi-thrust yamaha, replacing it with my little jewel 3.5 Tohatsu i bought off a friend over in Klawok - its new and the prettiest kicker i ever seen, also, it can double as my cruiser/explorer AIRE canoe i just build a ss kicker mount for ...

this is one fun little basterd! i can zoom around on plane at 13 + mph with the milage at like 50 or 60 mpg i think!

so anyway that is the plonmon the future i see, we might be up there with Europe in fuel prices soon

also, hacking off 250 to 300 pounds is going to make me more navigable on the river! im excited

if there is interest, its pretty easy and cheap to ship my old engines to the states via our barge lines you could hear how the main engine sounded in the video - if we have any rebuilder on the site?

i hope that don't get me busted! lol

also had my heart set on the new Honda 90 to

that last long trip to port beuclair (like 80 mi one way) tolld me i could get away from my speed adiction i got from the old 140 Johnson and the F-115 (like 30+ mph cruise!) i enjoyed so much the trip at them good old CD speeds of 20 or so, i now can get bok to it mon

most trips i make are only 20 miles

when we first got the RedFox we went all over creation (open sea coast) loaded up - - - with the old worn out 70 Johnson!

so return to the past i guess, its wonderful to have made such a good future decison with that old classic! you can put a big honkin motor on them or just a dinky one and still rip around like an idiot!

sorry - tmi again huh
