Same place as yours. Somewhere there was also a discussion of why the epa rates the engine at 350.

FIFY but that is definitely something to consider. There is a common trend in stolen boats.

Then that would be here:

http://www.epa.gov/otaq/certdata.htm#marinesi

Click on 2014 or 2015 data. Yamaha F350 is rated at 261 kw. Multiply that by 1.341022 and you get exactly 350 hp. The Yamaha F300 is only 278 hp however. Since I'm not here to knock other engines I won't continue to post what the epa has stated. Maybe they're full of crap too though?

The F350s will be discontinued starting June of this year.

How do you search the EPA website to find the KW data?

Be nice to see them offer a 350 in the same V6 platform as the 300.

That same statement was made LAST year.
When a new "replacement" is announced, I would expect that, not before.

Actually, the EPA website does not tell you which 4.2L model the 278hp rating is for. They only list one rating. It may be an average for the 4.2L models. A better source is the CARB engine database. It shows virtually every model separately. The F300 is reported at 221kW or 296hp. All of this CARB and EPA data is self-reported by the manufacturers.

(Sorry: Did not realize I was responding to a 4-yr old comment when the thread was "re-awakened".)

I cannot imagine they would do that. Too much of a downgrade in torque.

My bad, I did not get it. Sorry.
The XTO425 is not a replacement for the F350.
It was designed for a different application.
The two should not be thought of as interchangable on most applications.
