At the Miami show Seven marine had a pair of killer motors
They are the same motor that is in the Cadillac STS but marinized...

Cost: brace yourself... 70K a piece. I guess if you can afford these then the 5 bucks/gal gas we will be paying this summer does not feel so bad. But I bet it boogies!

It is still gonna hurt but glad I have a diesel.

You'll need to bring your 12' surfrod onboard to swim a fish around the transom and over those behemoths.
