How are the Eco Techs holding up

Postby keebo » Tue Sep 02, 2014 11:04 am

I know it's been about a year or so since the eco threads, how are these motors holding up after a year of running :?: :?: :?:

As far as I know the only thing that has failed other than because of human error such as radiator getting hole etc...is this

That's not to terrible, I'm looking at putting one together so I guess I'll find out. What's the best box ratio and prop size for these things? I was thinking a 2:68 and ngq. On a 12-13' hamant hull.
Soon as the 470 boat I have sells I can get moving on it. I'm all for quiet and easy on gas

Keebo, the NGQ is a direct drive prop. You would need the NGR for reduction.

We do have a few small blocks and Ecotec engines with reductions using NGQ blades and they are working great, but if you are considering a 2.68 then yes you will need an R or NGR setup.

I think he said he had fueling issues in his first junk yard motor but has since replaced it. Wonder how many hours he has on the second one now?

Well a melted piston isnt so good.
My mistake on the prop for sure, left hand vs right.

Is the 2:68 and a ngr feasible for these motors????????? Whats everyone else got on them??
How big a prop can ya put on them?

Depending on which motor, you can swing 2-3 blade 80" Maximus(widest blade we make). Chuck outfitted a 2.0 LHU with a 2 blade 74" short Max blade and we ended up adding a 3rd because it needed too much pitch. A 2.3 reduction matches them really well. Didn't much care for the 2.68.

And yeah, Simpsons was ran too lean. Bad combo for a turbocharged motor.

I am impressed if one of these. Motors spins a Maximus, I have a friend who has a pretty nasty 406 sbc and he uses the 3 blade 80" Maximus, it is a tractor to say the least. So is it possible for a turbo 2.4 to use this prop in stock. Fashion or does. It need tuning upgrades to achieve this.
So 2:3 gear box or belt? Thanks in advance for the replys, totally new route for me

Sure wouldn't mind a blue lightning belt drive kinda like them

Only real failure so far has been the starter. The return spring on the bendix broke and the ring gear was slowly chewing away the teeth on the starter. We replaced it before it left us somewhere.

The two engine failures I know of are my first engine and Dave Simpsons first engine. Mine was due to a 1 inch diameter hole in the radiator that I didn't see in time and asked the engine to put out 400 or so hp at 260+ F. My fault for sure...

Daves engine ran lean as he didn't know the lift pump to the direct injection pump had to have a higher pressure than he had it. Again, human error.

So far so good with them. They swing a big prop. Mine is the smallest out of the currently running 2.0 ecotecs and it is a 76" 3blade Maximus behind a 2.35 ox drive. Set on "2" pitch I turn the motor 5200 on trailer. My signature has more info.

Replace factory turbo with any of the aftermarket ones available for the engine as a bolt on will get you there.

Stock turbo engines range from 300 to 340 and swing the same prop.

Well I have a 1.4 liter making 180 hp, got over 250 hours on it and ride it hard no mercy on it gas an go like the wind getting 8 to 12 miles to the gallon, use about 8 gals a day. People like to bash it when I first started to ride it but I can say I have rode it in down pooring rain, got 8 inches of water in the boat and it never missed a stroke load it down with camping gear for the weekend an fill it full of fire wood an still run ground an not miss a stroke

Again, thanks for the info. I think this will be a cool build, may take a little while probably about5-6 months for water ready but cool none the less.
May have to pick y'all's brain a bit on the way so thanks in advance.

Going to have to be patient for sure, but I am shooting for 5-6 months. If it takes a little longer thats ok too because I won't be boatless throughout the build, but I am looking forward to the end result.

Saw Dave on the Ridge at Kissimmee a couple weeks ago. He was there with two other boats. When he left, his seemed to do it with the least amount of effort and was by far the quietest.

Getting ready to send my 12x7 DB up to Chuck for a 1.4liter and really anxious to see how it works out. Is that a Cypress prop on your rig? I'm debating between that and a 2 blade Sig. Any thoughts on the difference?

Had my junker out with my girl last weekend.
We rode about 50 miles round trip, going way south of Camp Holly.
I spent most of the ride at a low rpm, so she could enjoy it.
I topped it off afterwards, 7.5 gallons.
My biggest complaint is the 'rattle' just off idle from my second hand Rotater gearbox.
Mine is normally aspirated by the way.
