Common Question of SI-TEX 12CI Pumpset
What does the 12CI Pumpset provide?
The SI-TEX 12CI Pumpset is a 12VDC hydraulic autopilot pump set for compatible steering systems. The 12CI designation identifies intended cylinder capacity. Confirm hydraulic fittings, hoses, control computer, battery, wiring, pump direction, and hydraulic autopilot system compatibility before installation.
What cylinder size fits it?
The 12CI designation indicates compatibility with a 12-cubic-inch hydraulic cylinder, subject to SI-TEX documentation. Confirm the actual steering-cylinder volume, hose dimensions, pump capacity, voltage, current draw, control unit, and mounting requirements before purchase.
Does it operate a windlass?
No. The SI-TEX pumpset controls hydraulic steering and does not handle chain, rope, gypsy, or anchor drums. It is not an anchor windlass component. Use dedicated equipment for marine anchor retrieval.
