SI-TEX SP-70-7 Mechanical Dash Drive w/Built-In Feedback

Description

Connect a compatible mechanical cable-steering helm to the SI-TEX SP-70-7 Mechanical Dash Drive, a 12V rotary actuator with an internal rudder-feedback sensor. The drive uses a reversing DC gear motor and direct dashboard helm interface for standard push-pull cable systems. Its 215 mm behind-dash depth and 3.8 kg, or 8.4 lb, weight should be included in dashboard clearance, cable routing, mounting support, and service-access planning.

Maximum cable thrust is 150 lb, while typical current draw ranges from 3A to 5A and can reach 12A under load. The drive works with SI-TEX SP-70 and SP-80 autopilot computers through a standard quick-connect cable. The integrated feedback sensor removes the need for an external feedback rod only within a compatible mechanical steering installation.

Key Specifications of the SI-TEX SP-70-7 Mechanical Dash Drive

• The 12V mechanical rotary dash drive connects directly to compatible standard push-pull cable steering through a dashboard helm interface.
• A reversing DC gear motor provides the documented rotary cable movement for compatible SI-TEX SP-70 and SP-80 autopilot computers.
• The internal rudder-feedback sensor forms part of the drive assembly, eliminating an external feedback rod in compatible installations.
• Maximum cable thrust is 150 lb, requiring confirmation that the existing helm and steering cable support the drive load.
• Typical current draw ranges from 3A to 5A, with a 12A peak load for electrical-circuit planning.
• Behind-dash mounting requires 215 mm drive depth, plus room for direct helm connection, cable routing, and inspection access.
• The 3.8 kg steel and ABS drive assembly requires suitable dashboard support for the documented mechanical actuator installation.

Drive and Steering Integration

This SI-TEX drive is not a complete autopilot system. It requires a compatible SP-70 or SP-80 processor, mechanical cable steering, a suitable helm connection, and a correctly sized 12V electrical circuit. The internal feedback sensor is integrated into the actuator, while the rest of the autopilot system remains separate.

Confirm dashboard depth, steering-cable routing, cable geometry, helm connection, and service access before installation. The product information identifies a protected interior drive but does not provide an IP rating. Follow SI-TEX installation instructions for mechanical connection, cable alignment, circuit protection, feedback setup, and commissioning.

Why Choose the SI-TEX SP-70-7 Mechanical Dash Drive

The SI-TEX SP-70-7 Mechanical Dash Drive combines a reversing 12V motor, 150 lb cable-thrust limit, internal rudder-feedback sensor, direct push-pull cable connection, and behind-dash installation. Its 215 mm depth, 3A to 5A typical draw, 12A peak load, 3.8 kg weight, and SP-70 or SP-80 processor compatibility provide specific checks for a mechanical cable-steering autopilot system.

Setup and Network Considerations

Confirm that the boat uses a compatible standard push-pull mechanical cable-steering system and an SI-TEX SP-70 or SP-80 processor. Check the dashboard for 215 mm of drive depth, then plan the direct helm connection, cable route, 12V circuit, and access for inspection. Keep the drive and cable system aligned according to SI-TEX installation documentation.

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-70-7 drive. Mulmarine.com can help you review dashboard depth, cable-steering compatibility, 150 lb cable-thrust capacity, integrated feedback requirements, processor compatibility, and 12V power needs before purchase. Review the applicable SI-TEX warranty coverage and documented package contents before ordering.

Before Ordering the SI-TEX SP-70-7 Mechanical Dash Drive

Confirm that your vessel uses compatible standard push-pull cable steering and an SI-TEX SP-70 or SP-80 processor. You should verify 215 mm behind-dash clearance, direct helm fitment, steering-cable routing, 150 lb cable-thrust compatibility, 12V circuit capacity for up to 12A, dashboard support for 3.8 kg, and complete autopilot installation requirements before purchase.
