trim angle, rooster-tail, poor performance

Hi all,
I have a small (14 ft) wood boat that I built myself. I put a 25 HP
(Suzuki 4 stroke, manual trim) outboard on it. The angle of the
transom is such that the outboard is always trimmed in (even when I
adjust the bracket to the most trimmed out pin). The outboard may also
be a little bit high. The cavitation plate is at an angle in the
water, the front is lower than the back, the front is probably level
with the keel or 1/4" high, while the back is higher than the keel.
What I have noticed in the water is that the boat creates a lot of
spray, a big rooster tail appears behind the boat (maybe 4-6 ft
behind), and the performance seems quite sluggish. I am a little
confused as I expected that a trimmed in motor would not generate a
rooster-tail of water coming up, quite to the contrary that it would
push water down.
Could the trim angle or the motor height be causing this problem?
Thanks

One correction to my post, the cavitation plate is at an angle, the
front of the cavitation plate is higher than the back (I wrote the
opposite in my post).
