The inventive trim tab 10 is formed of a single piece of tough, rigid resin providing an integral mounting plate 12 and a lifter 11 extending aft from a bottom region of a power boat transom 15. Mounting plate 12 is formed flat to fit against the transom. Lifter 11 extends aft from mounting plate 12 at about a right angle and has a trailing region curving down around a transverse axis aft of the mounting plate and below the lifter. A pair of semitubular surfaces 25 incline from an upper region of mounting plate 12 down to the curved region of the lifter. Lifter 11 also has side edges 20 that extend downwardly and run aft from the transom and has a downwardly extending ridge 21 that runs aft between semitubular surfaces 25.
