A trim control system includes a memory storing a plurality of trim profiles, each trim profile defining a unique relationship between a plurality of vessel speeds and respective propulsion device trim angles. The unique relationship is: (a) a calibrated relationship developed by determining optimal trim angles for a particular propulsion device powering a particular marine vessel at a number of tested vessel speeds and a number of different conditions; or (b) developed by modifying a nominal relationship between a number of vessel speeds and a number of corresponding trim angles. An input device allows a user to select one of the trim profiles from the memory so as to specify an aggressiveness of trim angle relative to vessel speed. A controller determines a setpoint trim angle corresponding to measured vessel speed according to the selected trim profile. The control system positions the propulsion device at the setpoint trim angle.
