SI-TEX SP-70-8 Mechanical Dash Drive w/Built-In Feedback

Description

Using a reversing DC gear motor and built-in rudder feedback, the SI-TEX SP-70-8 Mechanical Dash Drive connects directly with compatible mechanical cable-steering helms. This 12V rotary drive uses a standard quick-connect cable and a reversible rotary cable-motion arrangement. Its 215 mm behind-dash depth and 3.9 kg, or 8.6 lb, system weight should be considered when planning dashboard space, helm connection, cable routing, and structural support.

The drive supports up to 150 lb of cable thrust and draws 3A to 5A during typical operation, with a 12A peak-load requirement. SI-TEX SP-70 and SP-80 computers provide the stated processor compatibility. The internal rudder-feedback sensor is part of the drive assembly and removes the need for an external feedback rod only where the compatible steering system accepts this configuration.

Key Specifications of the SI-TEX SP-70-8 Mechanical Dash Drive

• The 12V rotary dash drive connects to compatible standard mechanical cable steering through a direct dashboard helm interface.
• A reversing DC gear motor provides reversible rotary cable movement for use with compatible SI-TEX SP-70 and SP-80 processors.
• Integrated rudder feedback is part of the drive assembly, removing an external feedback rod in compatible cable-steering installations.
• Maximum cable thrust is 150 lb, requiring verification of the existing cable, helm, and steering-system load capacity.
• Typical current draw ranges from 3A to 5A, with a 12A peak-load requirement for 12V circuit planning.
• Behind-dash mounting requires 215 mm of depth, allowing room for cable routing, helm connection, and service inspection access.
• The 3.9 kg steel and ABS drive assembly requires suitable dashboard support for the documented steering-drive installation.

Drive and Steering Integration

This SI-TEX dash drive is a mechanical actuator, not a complete autopilot package. A compatible SP-70 or SP-80 processor, matching push-pull cable system, suitable helm interface, and 12V power circuit are required. The drive connects at the dashboard helm and relies on proper steering-cable alignment for the mechanical interface.

Plan installation around the 215 mm drive depth, direct helm connection, cable routing, accessible mounting location, and 12A peak electrical load. The product data describes a protected interior-drive configuration but does not state an IP rating. Follow SI-TEX documentation for installation, alignment, electrical protection, feedback configuration, and commissioning.

Why Choose the SI-TEX SP-70-8 Mechanical Dash Drive

The SI-TEX SP-70-8 Mechanical Dash Drive combines a 12V reversing gear motor, direct push-pull cable interface, internal rudder feedback, and behind-dash mounting. Its 150 lb cable-thrust limit, 3A to 5A typical current draw, 12A peak demand, 215 mm depth, 3.9 kg chassis, and SP-70 or SP-80 compatibility provide relevant integration details for a mechanical cable-steering autopilot system.

Setup and Network Considerations

Confirm compatibility with a standard push-pull mechanical steering cable and SI-TEX SP-70 or SP-80 processor before ordering. Check the dashboard for 215 mm clearance, plan the quick-connect cable route, verify direct helm compatibility, and provide a 12V circuit capable of supporting up to 12A. Use SI-TEX documentation for mounting, drive alignment, cable connection, feedback setup, and autopilot commissioning.

Warranty and Support

SI-TEX warranty terms vary by product and region, and the supplied specifications do not provide a named warranty period for the SP-70-8 drive. Mulmarine.com can help you review cable-steering compatibility, dashboard depth, internal feedback configuration, 150 lb cable-thrust limit, SP-70 or SP-80 processor requirements, and 12V circuit capacity before purchase. Review the applicable SI-TEX warranty coverage and documented package contents before ordering.

Before Ordering the SI-TEX SP-70-8 Mechanical Dash Drive

Confirm that your vessel has standard push-pull cable steering and a compatible SI-TEX SP-70 or SP-80 processor. You should verify the 215 mm behind-dash depth, direct helm interface, cable route, 150 lb cable-thrust limit, 12V circuit capacity for up to 12A, 3.9 kg mounting support, and complete mechanical autopilot requirements before purchase.
