That 525 pkg is much heavier therefore robbing HP to push same boat with pair OB

yes you are right a pair of 525's and a pair of 300hp outboards are not apples to apples. That is why you need 4 300hp outboards to match the performance you get from a pair of 525's and why the 525's are actually lighter, faster and better on fuel to get the same performance.

Sounds terrible, and looks like it runs worse than it looks. Good thing there's no market for those :lolhit:

Very awesome.

Since we have an outboard version, and a sterndrive version...here's mine hooked to a Berk jet pump

....at 8000+. Now that's music ;)
I love the sound of a stout big block but a screaming 3 liter two stroke V-6 making 450+ HP's, whats not to like?

BTW, I talked to these guys at the Miami show last yr. Very impressive and I think they're on to something.
