Joystick and Trim Control

While using the Axius joystick, the best boat control is achieved when the sterndrives are in the full down (in) position. Full down
(in) trim maximizes propeller efficiency allowing the boat to move parallel with the joystick command. The joystick will function
while the sterndrives are trimmed up (out), however control of the boat may be limited or altered because the inefficiency of the
propellers at or near the top of the water surface.

Trailer and Trailer Limit Position

On digital throttle and shift controls, the trim button (if equipped) also functiones as a trailer button that trims the sterndrives to a
limited up (out) position suitable for trailering purposes only. Based upon engine RPM, the system limits the amount of trim up
(out) and the availabilty of trailer position. The trailer limit function is designed to prevent damage to swim platforms.
Depending on the type of control or panel, the trailer position includes a single integral button to operate both sterndrive units
simultaneously or separate buttons for each sterndrive unit.

Trim without Key

The Trim Without Key mode allows trim operation after the ignition key switch is turned off. To avoid injury or product damage,
do not attempt any engine‑ or sterndrive‑related repairs or maintenance until performing the Wide Open Throttle Reverse
operation to end the Trim Without Key mode.
Trim without key is a method of allowing trim operation after the ignition key switch is turned off. The command module and PCM
remain powered and process trim requests for up to 15 minutes after the key switch is turned off. The command module does not
process any requests other than trim during this period. Once the 15 minute period expires, the command module sends a
command through the CAN lines to shut down the PCM. On multi‑engine applications, the time‑out is managed separately for
each engine.
The trim without key period may be ended at any time by moving the control handle to Wide Open Throttle Reverse (WOTR) with
the key off. To end the 15 minute period for the center engine in a shadow mode application, ensure all ignition key switches are
in the "OFF" position and both remote control handles are in the Wide Open Throttle Reverse (WOTR) position.

Electrical System Overload Protection

If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. You must find and correct the cause before
replacing the fuse or resetting the circuit breaker.
NOTE: In an emergency, when the engine must be operated and the cause for the high current draw (overload) cannot be located
and corrected, turn off or disconnect all accessories connected to the engine and instrumentation wiring. Reset the circuit breaker.
If the breaker remains open, the electrical overload has not been eliminated. Further checks must be made on the electrical system.
