The CMT-3854130Z is a zinc gimbal (transom) plate anode designed for Volvo Penta SX and DP-SM sterndrives. Mounted directly to the gimbal/transom plate assembly, it provides essential sacrificial protection—corroding in place of expensive drive components.

Parts Desk Insight
This is one of the primary protection anodes on Volvo SX drives. If this one is neglected, corrosion goes straight into the gimbal plate and transom assembly—two of the most expensive parts to repair. Always replace this anode proactively, even if others still look serviceable.
