Manuals & Guides

FAQ

Is the SP-70 compatible with my boat's steering system?

The SI-TEX SP-70 is designed to work with most Outboard, Inboard, and Sterndrive vessels that use either Hydraulic or Mechanical steering systems. If you're unsure about compatibility with your specific vessel, we recommend emailing us at service@omahasportsandgames.com and we'll help you confirm before you buy.

What does the SP-70-3 SKU include compared to other SP-70 variants?

The SP-70-3 package includes the SP-70 Control Unit, the 18CI hydraulic pumpset, and the rotary rudder feedback unit. This is a complete kit intended for vessels that require the 18CI pump capacity. Other SP-70 variants may include different pump sizes or feedback configurations - contact us if you need help selecting the right package for your vessel.

Can the control unit be used as a handheld device?

Yes - the SP-70 Control Unit can be quickly and easily removed from its mounting bracket for use as a portable handheld unit. This makes it easy to operate from different positions on your boat without needing a permanent second station.

What is the Ghost Rudder feature?

Ghost Rudder is a backup system that activates in the event of a rudder feedback failure. The autopilot uses its stored memory of previous rudder movements to calculate and continue making steering corrections, allowing you to maintain course control until the issue is addressed. It's a valuable safety feature for offshore and extended passages.

Can I add more steering stations to the SP-70 system?

Yes - additional steering stations can be added to the SP-70 using optional plug-in connectors. This allows you to control the autopilot from multiple locations on the vessel, such as both a helm station and a flybridge.
