E-TEC Engines in Higher HP

Has Evinrude mentioned when there are going with a higher horsepower E-TEC motor? (150/175 hp, 200/225 hp)

Last week at the New England Boat Show (our biggest), I was disappointed to see one, and only one, E-TEC motor in the entire show. A 75 hp. I found the Evinrude Service Rep (not sales rep) for the Northeast. He was explaining that work was being done on larger E-TEC's, but probably a year, or more, away.
What they believe this technology is capable of "right now" with their limited expirience, is about 40 hp per cylinder. so a six cylinder would be roughly 240hp. And they also know that the injectors "right now" are capable of working fine at 11,000 rpm. So potentially, they have got the basic building blocks for some super engines, with low emissions and low maintenance.
My own thought is that they have to prove themselves when it comes to "new technology", and prove to the world that this E-TEC is EVERYTHING they are claiming. They can't afford one more "folly", or they'll be history.
I would really like to see them succeed. More quality competition really helps us as boaters.
BTW, the exlanation of why there were not more E-TEC's at the show:
Well, I'm not bettin the farm on that one......

At the Toronto Canada boat show in January 04 there were probably 100 small etec's (probably 40-50hp) on nearly every small boat transom. They were everywhere in the show. They also had a large bombardier omc display. I was surprised. Fishing boats, pontoon boats etc.

Canadian boat show....Canadian company, why is that surprising? If it was in Japan, i would not expect too many Mercury engines to be at the Tokyo show, etc. Not trying to be a wise-ass, just giving my $.02

I've read reports that for the current Ficht injector technology 45 HP per cylinder and 7500 RPM are the maximums and that for the E-TEC injector technology the maximums are 80 HP per cylinder and 10,000 RPM. Those figures are just a function of how fast you can cycle the injectors and how much fuel they can pump for each cycle.
Current commercially available V4 and small block V6 Fichts produce up to about 29 HP per cylinder, but the big V6 produces almost 42 HP per cylinder. The lower limit for the V4 and small V6 here appears to be related to how much air you can get into the cylinders and perhaps how much heat you can extract, but not how much fuel can be pumped into the cylinder by the injectors.
The current E-TECs produce up to 30 HP per cylinder using the same size bore and stroke as the current V4 and small block V6 Ficht engines. If we were to apply the 40 HP limit to the E-TECs, it seems that we might be able to see an E-TEC 2 cylinder at 80HP, an ETEC 3 cylinder at 120HP, a V4 capable of producing 150 HP, the small V6 at 240 and the large V6 over 300 HP!
If they could push these limits and be reliable and clean, they would have folks beating a path to the Bombardier doorway in my opinion. However, I think they will play it safe and keep the power output down around the current 30 HP per cylinder mark, except for the large V6.

To look in the other direction, toward smaller motors, it was mentioned to me that the E-TEC design scales downward very nicely, too. Because the E-TEC can power its electronics itself and does not need a battery, the low-emission E-TEC can be adapted to applications like handheld weed trimmers and other small engine devices.

I was hoping for the new higher hp etecs to come out this year, but that doesn't seem possible.
Well, then I hope next year. Just hope my current motor will last that long.
