Lenco 7 degree Mounting Shim

The Lenco 7 degree mounting shim is a precision trim tab accessory engineered to fine-tune the running angle of your boat's hull. Whether you're running a center console, offshore sportfisher, or ski boat, achieving the correct mounting geometry is critical to fuel efficiency, handling, and ride quality. This shim bridges the gap between your transom and trim tab assembly, allowing you to dial in that perfect 7-degree pitch correction that many hulls require for optimal performance in varied water conditions.

Built to Lenco Marine's exacting standards, the 7 degree mounting shim is manufactured from durable marine-grade materials designed to withstand constant saltwater exposure, UV radiation, and the vibration cycles inherent to high-performance boating. The shim's fixed 7-degree angle correction ensures repeatable, consistent geometry installation without guesswork or field adjustments. Weighing just 1 pound, it's engineered to integrate seamlessly with Lenco trim tab systems, providing structural integrity without adding appreciable weight to your rig.

This shim is essential for anglers and boaters who've already invested in a Lenco trim tab system and need to correct mounting offset caused by transom geometry variation. Installation is straightforward—position the shim between your mounting bracket and transom, then secure per Lenco's factory specifications. If your boat porpoises at cruise, or if your Lenco trim tabs aren't responding as expected despite correct electrical function, a mounting angle correction via this shim often resolves the issue. Verify compatibility with your specific Lenco model before ordering.
