Optimus Limp Home Mode


In the event of a steering failure, Optimus Limp Home mode becomes available. Limp Home mode is a system override that may severely limit your boat's control. It should only be used in an emergency if you are unable to call for assistance. Proceed with extreme caution. Read the Optimus owner's manual and always wear a personal flotation device (PFD).


You are responsible for the safe and prudent operation of your vessel. Use of Limp Home mode does not relieve you of the responsibility of safely operating your boat. Avoid navigational hazards and never leave the motor controls unattended.

When available, the Limp Home button appears on the Optimus overlay bar. Refer to the Optimus owner's manual before using Limp Home mode.

To engage Limp Home mode from any screen, select Where To > Warning Manager > Steering Limp Home.
