Recently purchased a Caravelle 1750 FS with 135 Merc and Alpha One outdrive.
Saw the post about porpoising, and have a question.

My boat has power tilt/trim, with which I seem to be able to remove "most"
of the up-down motion by adjusting... Also on this boat was a "whale tail"
(hydrofoil?) mounted on the outdrive. A friend suggested I remove it 1) to
increase top speed (42 MPH with wife and kids is fast enough for now), and
2) to see if the porpoising went away.

Any experience regarding my friends comments? He does NOT own a boat, but
has grown up around them...
