The Martyr CMT-DPHKITA is an aluminum anode kit for Volvo Penta DPH and DPR sterndrives, built to help protect the drive from galvanic corrosion in saltwater and brackish water service. Seller and manufacturer listings consistently describe this as an aluminum kit for DPH/DPR applications, with mounting hardware included.
This kit is commonly listed as including a transom shield anode and a cavitation plate anode, making it a practical replacement set when servicing corrosion protection on the drive rather than replacing only one consumed piece at a time. Cross references commonly shown for the kit components include 3588745 / CM3588745 and 3863206 / CM3863206.
Key Features
- Aluminum anode kit for Volvo Penta DPH / DPR sterndrives
- Designed for saltwater and brackish water use
- Commonly includes transom shield anode + cavitation plate anode
- Mounting hardware included on multiple listings
- Helps reduce galvanic corrosion on expensive sterndrive components
- Common component references: 3588745 / CM3588745 and 3863206 / CM3863206
Engine Compatibility
Fits Volvo Penta DPH and DPR sterndrive applications. Multiple current listings specifically identify the kit for DPH / DPR drives, while one listing phrases fitment as DPH drives and includes the same DPH/DPR transom shield component pairing. Because drive variations and service history can affect fitment, confirm against your exact Volvo Penta drive model and existing anode layout before ordering.
Serial Number Fitment Notice
Please verify fitment by Volvo Penta drive model and serial number before ordering. This is especially important on sterndrive corrosion parts, where running changes, prior repairs, or mixed component installations can affect what is currently fitted on the drive. The published listings support DPH/DPR application, but serial confirmation remains the safest match method.
When This Part Needs Replacement
Replace the kit when the installed anodes are heavily wasted, pitted, cracked, loose, or reduced enough that they are no longer providing effective sacrificial protection. Sterndrive anodes should be inspected regularly during haul-out or service intervals, especially in saltwater and brackish water where corrosion loads are higher.
Installation Notes
Install on clean bare metal contact surfaces and do not paint the anodes. This kit is commonly sold with mounting hardware, and replacement is typically performed as a set to restore balanced protection across the drive. Confirm the included components match your current drive before installation.

Parts Desk Insight
A full anode kit is often the smarter buy on DPH/DPR drives because these drives are expensive to repair, and unevenly worn anodes can leave one area of the drive less protected than another. Another useful detail: aluminum anodes are widely promoted by Martyr for salt and brackish water because they offer broad protection and avoid the passivation issues zinc can have in some brackish conditions.
