S1000 Autopilot Installation Guide
Using the hydraulic hoses
Three, pre-assembled hydraulic hoses are supplied. Two of these are dark-colored, high
pressure steering hoses and the third is a transparent low-pressure hose.
The transparent hose is intended to help you check for air bubbles when bleeding the
system and must be used only to connect the autopilot pump reservoir to the lower
connector on the helm pump. It must NOT be used anywhere else in the system.
