I have a J14 (20" TRANSOM), with a long shaft 25HP Yamaha. The
quandary is, the cavitation plate is approximately 3 inches below
optimal performance position, and I would like to raise the motor that
amount. Does any one know of a transom riser that would fit on this
boat, and if so where can I purchase? Or, am I splitting hairs, and
raising the motor 3 inches won't really matter? I don't really want a
jack plate.

Thanks.
