Emergency Shifting
If the electronic remote control should develop a fault
and the drive unit can not be shifted there is an emergency
procedure to engage the IPS unit in forward gear.
To manually engage forward gear:
1. Stop the engine and remove ignition key from switch.
2. On the side of the IPS drive locate the solenoid valves.
Locate the harnesses to the solenoids and remove both
harnesses from the solenoids. Remove the cap nut from
the P or forward solenoid by unscrewing it.
3. Press in on valve A while turning the valve 1/2 a turn
counter-clockwise (spring action forces the button out).
The drive unit is now connected for forward vessel motion
and can not be disengaged using the control lever.
To manually disengage forward gear:
1. As you push in the spring loaded button turn the button
simultaneously clockwise 1/2 turn. Forward gear is now
disengaged.

marked S for reverse.
