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

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.

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.

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. 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.
