                        The shift gates are dropped down part way
                        over the jet thrust nozzles. The neutral posi-
                        tion balances forward and reverse thrust to
                        help keep the  boat  from moving, although
                        some movement may occur.

                        This function, which is called the thrust direc-
                        tional enhancer (TDE), helps to provide good
                        handling response when the steering wheel is
                        turned, even though there is less thrust avail-
                        able at low engine speeds.
