Torque gets you going. Horsepower keeps you going.

If one were to look at a graph of the torque curve of both the engines cited above, it might show that the 6.2 has less torque at lower rpm.

There's no replacement for displacement.

One way to make an boat perform better from stationary to plane is to reduce propellor pitch. Top speed will be reduced but boats often have plenty of speed at the top that is never used.

EDIT: A look at Mercruiser's website shows HP specs but not torque.
