Installation Considerations

The pump must be reconfigured if the boat is equipped with an unbalanced steering cylinder (page 3).

The pump should be mounted the pump horizontally if possible.

If the pump must be mounted vertically, mount it with the hydraulic connections facing upward.

Garmin recommends using the t-connector method to connect the hydraulic lines to the pump. See the diagram page 8 to view the alternate connection method.

To allow for easy pump disabling and removal, Garmin recommends installing shut-off valves in the hydraulic lines between the pump manifold and t-connectors.
