It converts the steering cylinder’s linear movement into an analog feedback signal, with a 300 mm (11.8 in) stroke and a waterproof body that can be mounted in splash-prone areas near the transom.\u003c\/p\u003e\u003cp\u003eAn 8.5 m (28 ft) cable supports routing from the steering cylinder area toward the helm, and the sensor mounts to the outboard drive unit cylinder using clamp-style mounting hardware so it follows steering travel directly. For outboard autopilot installations, it is used with the LFI3000 Mk2 Linear Feedback Interface (sold separately) to pass feedback to the autopilot steering computer.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e300 mm (11.8 in) stroke for tracking steering cylinder travel\u003c\/li\u003e\n\u003cli\u003eWaterproof feedback unit for transom wells and other wet mounting zones\u003c\/li\u003e\n\u003cli\u003eOutputs an analog position signal from linear steering movement\u003c\/li\u003e\n\u003cli\u003e8.5 m (28 ft) cable for practical stern-to-helm routing\u003c\/li\u003e\n\u003cli\u003eMounting approach intended to secure the sensor to the outboard drive unit steering cylinder\u003c\/li\u003e\n\u003cli\u003eUsed with the LFI3000 Mk2 Linear Feedback Interface (sold separately) on outboard applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eLF3000 linear feedback unit\u003c\/li\u003e\n\u003cli\u003e8.5 m (28 ft) cable\u003c\/li\u003e\n\u003cli\u003eMounting clamps and cylinder attachment hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe feedback unit mounts alongside the steering cylinder so the rod extends and retracts with normal steering travel. During installation, the key checks are alignment and full-range movement: the sensor should not be side-loaded, and it should not bottom out before the cylinder reaches either end of its stroke. Route the cable with a drip loop and chafe protection anywhere it passes through rigging tubes, splash wells, or bulkheads.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis unit is used on outboard systems where the autopilot needs a true steering position signal instead of relying only on drive commands. Clearance around the cylinder matters because the feedback rod needs room to move through its full 300 mm travel. If the steering uses a rotating Teleflex HC5345 cylinder, the LF3000 Seastar Swivel Kit provides wider clamp hardware intended for that cylinder style.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eLF3000 provides an analog feedback signal and is paired with an LFI3000 Mk2 interface on outboard installations so the autopilot steering computer can read rudder angle feedback. Keep any interface and connections in a dry, protected area when possible, and avoid running the cable alongside high-current conductors for long distances to reduce the chance of electrical noise.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis setup fits boats that spend real time on autopilot, such as center consoles on long runs, boats that troll for hours, and cruising outboards where steady course-keeping matters. It is also a sensible add-on when you want predictable steering response at low speed where outboards can otherwise feel “loose” to an autopilot.\u003c\/p\u003e","brand":"Simrad","offers":[{"title":"Default Title","offer_id":52269098500277,"sku":"QBP438198","price":467.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298458_qbp438198.jpg?v=1771541848","url":"https:\/\/www.qualityboatparts.com\/products\/qbp438198","provider":"Quality Boat Parts","version":"1.0","type":"link"}
