I could be wrong, but:
I predict that in the near future, performance boats will be substantially lighter than they are now. This will come about because (1) the big blocks simply won't be manufactured anymore at anything like an economic price point (they are only cheap because zillions more are used in cars and trucks), and (2) the cost of energy will go up due to global demand, not just US demand.
So if we will want to play, we'll need to adjust.
The golden age of US economic growth was when the US was an exporter of energy, up through the late 1960's. No economy can afford to send a trillion dollars overseas for the expense (not investment) of fuel.
We can "grow" lots of energy: Not enough for us to keep using it at the rate we have been; Plenty enough to use it as much as we need to.
If the US per-capita consumption of energy dropped to the level of all the countries that now have higher standards of living than the US, then we can easily "grow" enough energy.
If we keep burning as much energy as we have been, we'll be a third world country soon, so high HP will simply be irrelevant: nobody will be able to afford it, we'll all be poor.
So soon we'll need to make the boats lighter to be able to still use available automotive engines. Then the lighter, high HP/ low torque engines will work great. Then all of our gas bills for a weekend will remain reasonable.

It's funny reading back on this thread and seeing everyone's reasons why it can't be done or why a dohc would be a POS in a boat cause they don't make low end power. Now that merc makes them, people think its the best thing since sliced bread. Not saying the 1350 is a bad motor but its ridiculous how many people have the mind set "if it's not merc, it's no good".
