It is commonly used on boats up to about 50 ft when paired with a compatible Simrad autopilot computer.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12V DC reversible hydraulic gear pump for autopilot steering control\u003c\/li\u003e\n\u003cli\u003eFlow rate: 1.6 L\/min (98 cu in\/min) for responsive course corrections on mid-size hydraulic systems\u003c\/li\u003e\n\u003cli\u003eSupports cylinder displacement from 160 to 550 cc (9.8 to 33.5 cu in)\u003c\/li\u003e\n\u003cli\u003eO-Ring Boss (ORB) ports for clean, leak-resistant hydraulic connections\u003c\/li\u003e\n\u003cli\u003eIncludes 3 x ORB-5 to 9\/16 UNF fittings for common marine steering plumbing\u003c\/li\u003e\n\u003cli\u003eWorks with Simrad NAC-3 or AC42 autopilot computers and supports SteadySteer setups\u003c\/li\u003e\n\u003cli\u003eSpecified for installations on boats up to 50 ft when the full steering and autopilot system is correctly sized\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eMatch the pump to your steering cylinder displacement before ordering. This unit is sized for cylinders between 160 and 550 cc, which covers many hydraulic rams found on larger outboards, stern drives, and inboard boats.\u003c\/p\u003e\u003cp\u003eThis pump is one part of a complete autopilot system and requires a compatible Simrad autopilot computer (NAC-3 or AC42) to control direction and operation. It is not a standalone steering component.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the pump in a dry location with airflow and access for service, then keep hydraulic runs as short as practical to help steering response and simplify bleeding. Avoid placing it where it will see constant spray, bilge water, or direct engine heat.\u003c\/p\u003e\u003cp\u003eThe hydraulic ports use ORB sealing, so the seal is made at the O-ring rather than on the threads. Keep O-rings clean, start fittings by hand to avoid cross-threading, and tighten evenly.\u003c\/p\u003e\u003cp\u003eAfter plumbing, bleed the steering circuit completely and confirm there are no leaks under load before relying on the autopilot away from the dock.\u003c\/p\u003e\u003ch6\u003eOn-board use\u003c\/h6\u003e\u003cp\u003eThis pump is a common match for coastal cruising and sportfishing boats with hydraulic steering that need autopilot control for long runs, trolling, or holding a steady course in chop. It also fits larger center consoles and small to mid-size cruisers that fall within the listed cylinder range and boat-size guidance.\u003c\/p\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003ePUMP-3 MK2 reversible hydraulic pump (12V)\u003c\/li\u003e\n\u003cli\u003e3 x ORB-5 to 9\/16 UNF fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRecheck hydraulic fittings after the first few outings and inspect periodically for seepage.
