Description

The 194-CMBNT1AA (commonly referenced as CMBNT1AKITA kit A) is an aluminum trim tab anode kit designed specifically for Bennett trim tab systems. This kit provides sacrificial corrosion protection for trim tabs by mounting directly to the tab plane, protecting the actuator and surrounding hardware.

Constructed from marine-grade aluminum, it delivers long-lasting protection in saltwater and brackish environments, outperforming traditional zinc in mixed salinity conditions.

Parts Desk Insight

Trim tabs sit in a high-current corrosion zone, especially near actuators and hinges. This kit protects one of the most exposed areas on the boat—without it, you’ll often see corrosion start around mounting hardware first, which can lead to premature trim tab failure.
