1. A method of controlling an electric marine propulsion system configured to propel a marine vessel, the method comprising:
receiving a user-set distance;
determining a remaining distance based on the user-set distance;
identifying a battery charge level of a power storage system on the marine vessel;
identifying an energy utilization value;
determining an output limit based on the remaining distance, the battery charge level, and the energy utilization value; and
automatically controlling the propulsion system so as not to exceed the output limit to enable the marine vessel to travel the user-set distance without recharging the power storage system.
