13. What does the E stand for at the end of part number?
The E stands for edge mount. A standard Lenco Trim Tab requires at least 15" of transom space from where the trim plane is mounted near the bottom of the boat to where the actuator mounts to the transom. On an edge mount you only need 11" of transom space. We do this for boats with limited transom space, and to fit under swim platforms and rub rails. The edge mount is available in the Troll-N-Tab and Trim Tab models.
