Twin Steering System
2 hoses from helm to the outer most fitting on each cylinder (i.e. the starboard most fitting on the starboard motor, and the port most fitting on the port motor). On the 2 inside fittings, you run a hose from cylinder to cylinder.
3) bleeding the system (you must have the motors mounted, and the tie bar in place). I find it easiest to only hook up the hose going to each cylinder first (that way you can turn the motors back and forth by hand), and purge out all of the air in the hose and 2 cylinders. Then hook up the 2 hoses from the helm and bleed the system as described in the instructions.
4) all other connections on each motor hook up just as if you have a single remote steer motor (i.e. nothing else joins the 2 motors together).
