E-tecs are thirsty....

[glen e]

It's raining here, it's winter...let's have a good spirited discussion - I know this will get one going...

E-tec's are great engines but they don't seem to get the same MPG as their counterpart 4 stroke. Doing the math using these two tests (that are by BRP and Yamaha on the same boat), the E-tec burns 3 gallons more across the operating range. Hell, at a 1K rpm troll, the E-tec burns twice as much as the F250. Assuming you cruise 60% of the time and gas costs $3.50, the E-tec will cost you 630 dollars more in gas than the Yamaha every 100 hours. Assume the 2S vs 4S oil thing is a wash. To me 630 dollars difference is significant. And if e-tecs only need service every 300 hours that's 1890 dollars difference. And the delta $$ will only get worse as we go above 3.50 per gallon. So I don't get slammed for having an agenda, I have left the Mercury and Zuke out of this discussion but both do even or better MPG than than the F250.


The Mfr reports here. Remember they are motor mfr reports so we assume they using the best prop for them and engine mounting:

THIS IS NOT MEANT TO BASH, THIS IS JUST FACT...supplied by both engine manufacturers on their sites..

With all this said they are still an engineering tour-de-force. They are reliable. The lack of need for 100 hour service appeals to me and being NMEA 2000 compliant is a huge plus. If they solve this thirst problem, add power steering standard, Vesselview and fly by wire, they would the hot ticket, IMO.s.....but they are thirsty right now....wonder what the new 300 burns?

Wow! Am I reading that right? Look at the mileage at trolling speeds. 1500 to 2000 RPM. Yikes. Like most two strokes, even the e-tec just doesn't like to go slow.

I post this because on other sites for the last 3 years the etec fanatics would have you beleive they beat everyone on all counts...certainly not true..and if you want to see what a verado or Zuki does - it's even better....my boat - the exact boat in these tests with a full tank gets 2 mpg...and I've got 100 more HP!

While I don't give 100 percent credibility to Yamaha's numbers, in my experience, they don't seem to ever be off by more than 10 to 15 percent. But to heck with the Yamaha numbers. Just look at the E-tec numbers by themselves. Yow!

[ken2]

One thing I noticed.
The Etecs are in hole number 2. The Yamaha's are in number 4.
(yamaha's are 2 holes higher)

I know prop choice can change optimal engine height, But I see manufactuers with wrong props and engine height all the time, I wonder if they actually got it right for this one.

But most of the Etech boats I've ran... the economy wasn't stellar.

go look at my post over there 20 min ago....what I posted:

finally got the time to take the same boat out as the tests I quoted...The boat is completely filled with fuel - 2 people, 4 batts and O-5 mph wind - enertia 19's - 82 deg
Now if we really wanna make this interesting let's look at my data..

the e-tec 250's burn 24.35 gph at 4000 rpm making 35.2 mph

the verado 300's burn 20.2 at 4000 rpm making 34.8 mph

now going to my original post, I wrote nothing but to say that at $3.50 per gallon the etec burned 3 gallons more for 10.50 a crUIsing hour

with the v300's it's 4.15 gallons x 3.50 = $14.52 per hour

AND I MAKE 100 MORE HP!

Ok boys...pick um them bashing sticks and get started....I'll get the popcorn...

it is really amazing how fanatical that site is...I posted this in 4 places
fl sportsman - thread dies after 5-8 posts - a few agreed, some disagreed - but nice and calm

here: nices and calm

THT: posted within a thread and the same fanatics at CW ran around with their head cut off

and CW: I'm sure a few guys called in sick so they could look up other tests that refuted mine...

I don't understand it...if someone posted two tests with a verado coming in last - I would post:

"Yup..sure looks like it - who cares, I got digital shift, vesselview, power steering so I guess I can't have it all."

Not the fanatics..they act like you've publicly insulted thier mother...."

Glen,

What makes me laugh at continuous is that the moderator seems to take part in all these crazy threads and does not try to calm them or put people in their place.

He throws gas into the fire with his own sometime idiotic comments. Then sits back and many years later will ban someone for posting comments not any worse than his own. Jim certainly does not lead by example.

I throughly enjoy your sight!! You moderate it correctly from my point of view.

Every site has these arguments, I call them Ford vs Chevy wars.

I my opinion BRP created this etec vs the world with there heavy biased public ads.

Nuts to 'em all!! Nuts to all the E-tecs, Verados, Hondas, Yamahas, Suzukis

I WANT a pair of the Mercury Optimax JP's

Yeah they are only 185 HP, but they are lighter than my Yamadog 208's and the fuel numbers are beyond delicious. But, apparently we cannot buy them.
