What is the difference between an E-tech 250 H.O. and a 300 H.O. (2011)

50 HP; yes but they are both 3.4 liter motors. I suspect that the main difference is a $1,500 ECU and stickers. Does anyone know for sure?

They are not all the same, the 250HO is a 3-Star Ultra-clean emission engine while the 300 is only a 2-star rated engine

The 300 is not an HO.

No its not a HO, but this one is, right around 315hp at 7000rpms, and yes I know they dont rev that high, but when you have the Secret BRP EMMS you can pop it in and go for some High RPM runs.... http://www.youtube.com/watch?v=Q5gDdEuuMgE and it comes from this Lil Secret Lake County Ill shop http://www.youtube.com/watch?v=c_X3DFzSE8w and NO MERCS CAN COME CLOSE, 260s, 280s, 300 Drags, 250 XS's or 300 XS's......seriously http://www.bassboatcentral.com/smileys/thumbsup2.gif

What mid and lower are they running on that red and yellow tunnel hull? Looks like a coned magnum....but the mid looks like a merc offshore (with the snout) http://www.bassboatcentral.com/smileys/popcorn.gif

Looks like the white tunnel hull is running a sporty LU......with a little help from the Taylor brothers down in Alabama. http://www.bassboatcentral.com/smileys/popcorn.gif

http://www.bassboatcentral.com/smileys/roll.gif Sorry to laugh...but I have asked this question on many sites. Never got a straight black and white answer from any of the experts. Its some big secret I guess....or there isn't ANY difference besides lower-units (oops, scratch that), graphics and CARB rating.
That said, I would rather have the 300 just cuz it says 300 http://www.bassboatcentral.com/smileys/doh.gif http://www.bassboatcentral.com/smileys/wink.gif

Well you can always put 250 stickers on it. http://www.bassboatcentral.com/smileys/Laugh.gif

I have no clue what it was but last year at Jasper there was a solid white Evinrude (no stickers or markings) that SMOKED EVERYONE in his class. It was one bad motha.....

I think was a dave bush motor, or a monty

Where you there to see it? It was solid white and had a hole cut in each side of the cowling about 5" in diameter. I though I had a picture of it but I didn't. I do have some video but I would have to dig it out. Man, that thing was a BEAST!

Well genius the thread was about E-tecs. Monty generally mods loopers 60 and 90 * motors.

The thread may be about an etec, but he is asking about a motor that was not an etec.

Lets try to be nice moderator.

Yes i was at Jasper !!!
