Look at the horsepower

It's the most I've seen on a recreational boat with outboards.

But....

-Why are there two different brands of motors?
-How much weight can the stern hold? Those engines look heavy.
-What would the controls be, Mercury or Yamaha?
-Do all the props rotate the same way?
-Why are there three different lengths of lower units?
-How much gas does that guzzle?
-Why does a boat that size (doesn't look that big from the picture) need 950 horsepower?

I guess the Yamahas are kickers.
