Furuno PUMPLA11-12 12v TYPE1 L Linear Drive Unit
Furuno PUMPLA11-12 12v TYPE1 L Linear Drive Unit — Product description
Upgrade your boat's autopilot performance with a reliable linear drive unit built for demanding marine environments. This compact hydraulic actuator seamlessly connects autopilot systems to mechanical steering setups like wire, cable, or chain drives, delivering precise control and effortless handling on the water.
Engineered for vessels up to 22,000 lbs displacement, it combines a heavy-duty brass cylinder with a powerful drive unit, ensuring smooth operation even in rough seas. Boaters appreciate its rugged construction that stands up to saltwater exposure and constant use, minimizing downtime and maximizing your time enjoying the helm.
Why This Linear Drive Excels on the Water
Unlike basic actuators, this unit offers balanced cylinder design for even pressure distribution, reducing wear and extending service life. Its stainless steel braided hoses resist corrosion, while the 12V motor pulls just 3-6 amps on average—perfect for battery-conscious setups without draining power reserves during long passages.
- Effortless Hard-Over Performance: Achieves full rudder swing in about 13 seconds, ideal for quick maneuvers.
- Impressive Torque: Generates up to 6280 in. lbs. at 8-inch rudder shaft distance, handling stiff steering systems with ease.
- Compact Footprint: Fits tight engine rooms or lazarettes without sacrificing power.
- Quiet Operation: Minimal noise from the hydraulic pump means undisturbed navigation, day or night.
Perfect for sailboats, powerboats, or trawlers where responsive steering enhances safety and comfort, especially during autopilot reliance in open water.
Inside the Robust Design
Crafted with marine-grade materials, the 2-inch bore brass cylinder paired with a 1.5 x 9-inch RAM provides a 9-inch stroke and 13.1 cubic inch swept volume. At 500 psi, it delivers 785 lbs of thrust—enough to overpower wave-induced loads on larger hulls.
The solenoid draws only 1.5 amps at 12V, ensuring compatibility with most DC systems. This setup translates to reliable performance across a wide range of boat types, from coastal cruisers to bluewater explorers.

Streamlined Setup for DIY or Pro Installs
Integration is straightforward: mount the drive unit securely, connect hoses to the cylinder, and wire to your autopilot's control head. Pre-filled with marine hydraulic fluid, it minimizes air purging hassles. Align the cylinder parallel to the rudder post for optimal leverage, and you're set for plug-and-play operation.
Pro tip: Pair with a helm pump for full hydraulic steering redundancy, boosting reliability on extended voyages. Regular checks on hose connections prevent leaks, keeping your system primed.
Ideal for These Boating Scenarios
- Offshore Fishing: Holds course steadily against swells, freeing hands for rods.
- Weekend Cruising: Smooth autopilot takes over for relaxed passages.
- Liveaboard Comfort: Precise tracking reduces fatigue on long hauls.
- Upgrade Path: Matches performance needs for mid-sized vessels seeking better control.
Longevity Through Simple Care
Flush the system annually with marine-grade fluid to avoid contamination. Inspect seals quarterly for wear, especially after heavy use. This proactive approach ensures decades of service, far outlasting cheaper alternatives prone to pump failures.
Frequently Asked Questions
