There is no way to know the answer to that question w/o knowing several
other factors and having a PhD in mathematics or the like.

Perhaps a better way to answer the question is to know _why_ your asking and
_what_ your trying to know from the answer.

Trimming the engine up moves the thrust angle of the engine in comparison to
the boat. Basically it usually pushes the front of the boat up and, to a
much lesser extent, the back of the boat downward. More importantly it also
points the thrust of the prop/engine upward and, when at an extreme angle,
out of the water. This is what causes a "fish tail" behind a boat (a spray
of water out and upward from the boat). When this occurs there is usually
less thrust power from the boat as it actually now has less resistance to
push upon. The stability of the boat is usually reduced at this point as the
hull of a boat usually has a steep angle in the front, flattening as it goes
backward.

I have a question regarding a bass boat and a larger motor.

when I get my boat on plane I know is a small portion of the boat actually
on the water. What effect does trimming the motor up have on the boat, is
there more or less boat actually in the water?
