Mounting hardware is included with the pump, but it may not be suitable for the mounting surface.
2.If necessary, purchase the mounting hardware.
3.Hold the pump in the intended mounting location and mark the locations of the mounting holes on the mounting surface, using the pump as a template.
4.Using a drill bit appropriate for the mounting surface and selected mounting hardware, drill the four holes through the mounting surface.
5.Secure the pump to the mounting surface using the selected mounting hardware.
Connecting the Pump to Hydraulic LinesNoticeDo not attempt to use the autopilot to steer the boat until you bleed all air from each part of the hydraulic system (page 3).
When adding hydraulic line to the system, use only hose with machine- crimped or
Do not use plumber’s tape on any hydraulic fitting. Use an appropriate thread sealant rated for marine use on all pipe threads in the hydraulic system.
Before you connect the pump to the hydraulic lines, refer to one of these diagrams to find the correct place to add the pump and fittings to the hydraulic system.
