Lenco 4 1/4" Stroke XD Actuator 5/16" x 3/8" 12v

The Lenco 4 1/4" Stroke XD Actuator 5/16" x 3/8" 12v is a precision hydraulic component engineered for marine trim and tilt systems on recreational and professional vessels. Built by Lenco Marine, a trusted name in boating hydraulics, this actuator powers the automatic trim-and-tilt functionality that allows anglers and boaters to raise or lower outboard motors and sterndrives with the push of a button. Whether you're navigating shallow flats or adjusting your running angle in choppy offshore conditions, a reliable actuator is essential for boat control and engine protection.

This XD-series actuator delivers a 4 1/4" stroke length, providing the range needed to achieve full trim-up and trim-down positions on most medium to larger hull applications. The 5/16" and 3/8" port connections accommodate standard SAE hose fittings found on Lenco integrated pump systems, while the 12-volt DC power rating ensures compatibility with standard marine electrical systems. Internally, the actuator uses sealed rod and piston designs to withstand saltwater corrosion and maintain consistent hydraulic pressure across thousands of cycles—critical when you're running long days on the water and expect instant response when trimming out of a turn or tilting up to clear shallow structure.

Replacement and retrofit applications benefit most from this actuator, particularly for boaters maintaining older Lenco systems or upgrading to XD specifications for improved durability and response speed. Installation typically requires basic mechanical knowledge and access to the trim cavity; ensure the boat is hauled or securely positioned before disconnecting hydraulic lines. Verify your existing pump manifold and hose connections match the 5/16" x 3/8" port configuration to confirm proper fit. At 4 pounds, the compact design fits within standard mounting brackets used on recreational fishing boats, center consoles, and cabin cruisers running outboard or sterndrive platforms.
