Moving the lever further forward will cause the transmission to lock out trolling and advance the throttle. The factory set defaults will limit throttle to 40%. The trolling defaults -- as shown in Appendix D -- can be set to a variety of operating modes. Contact your dealer for details, or see technical manual.
