I was just having this discussion with an outboard buddy of mine the other day. They need to build an all aluminum, inline 4 (2.0 liter), twin cam, 4 valve per cylinder turbo that would easily put out 400hp and weigh no more than an old 2.5/V6. That same basic engine (2.0 I4 turbo) has been the mainstay of Audi/VW at around 300hp/EPA legal in several different cars for the past 5+ years or so - with a 5 year/50,000 mile warranty! I'm personally not a fan of the supercharged I6 route Mercury has chosen to stick with.

[QUOTE=skate;4260233] Aye Vito , Quadzilla is gazzed up and ready ... .>
It's got a screw bolted to the side, 400 would be easy but it would take 100 points on the fuel to do it.
50 lbs , not so easy unless you don't mind payin for mag castings and Ti fasteners ...
Gettin Merc to take their eye off of the 1650 package long enough to remember the outboard ..
ziemer:
They have the base platform for this, just need to get them to make a Race version... Would think 250-300 hp is achievable, drop 50 lbs and add a sportmaster...You're there.

That MTI looks amazing on paper. Order several guys so a few used ones trickle down to the used market quickly! 
My concerns with the portly 400 are fuel economy and high rpm longevity compared to the current 300XS. The 300XS has proven to be super efficient and 2 strokes love to be run on the upper end all day long. How well will the 4 stroke like being run near redline for extended periods and how much will it drink in comparison? Yes I realize it takes more fuel to produce 400 hp rather than 300, but if a cat could comfortably cruise/run at 95 mph with the 300XS, how much more (or less) fuel will the 400 drink to maintain the same speed? I know fuel economy isn't a high priority for most of us, myself included, but I'm intested to see how the two compare in economy and high rpm sustainability.
