Description
Product Overview
The Qiilu Boat Motor Trim Tab Anode is engineered from high‑strength aluminum alloy to serve as a sacrificial anode for outboard engines. Weighing just 6.1 ounces and measuring 7.01 x 5.39 x 2.68 inches, it fits seamlessly into the lower unit of Mariner 25‑50 2‑stroke and 4‑stroke models as well as Force outboards produced between 1997 and 2006. Its knurled head ensures a secure fit, while the corrosion‑resistant material endures harsh seawater environments without deformation.
Usage
