The Martyr CMT-832598Z is a zinc dogbone-style sacrificial anode for select Volvo Penta sterndrive applications. It is commonly cross-referenced to Volvo Penta 832598 and is designed to help protect the outdrive and transom plate area from galvanic corrosion in saltwater use. Martyr identifies this as CM832598, while current fitment references consistently tie it to older Volvo Penta sterndrive families.
This is a zinc anode, which makes it the correct material choice for saltwater environments. Common published dimensions are approximately 7.3 to 7.4 in. long, 1.6 in. wide, and about 0.9 to 1.0 in. thick, with 2 mounting holes.

Engine Compatibility
Commonly associated with select Volvo Penta sterndrive and outdrive applications, especially older 200–280 series references. Some aftermarket naming also associates it with SX / DP-style applications, but the strongest supported fitment reference is still the OEM replacement number 832598. Always confirm against your exact drive model and existing anode before ordering.
Serial Number Fitment Notice
Please verify fitment using your Volvo Penta drive model and serial number before ordering. This is especially important on older drives, where service history and previous repairs may have changed the anode style currently installed. Matching by OEM part number 832598 is the safest approach.
When This Part Needs Replacement
Replace this anode when it is heavily consumed, pitted, loose, cracked, or significantly reduced in size. A commonly used service guideline is to replace sacrificial anodes once they are around 70% eroded, so the drive keeps proper corrosion protection.
Installation Notes
Install on a clean bare-metal mounting surface so the anode has full metal-to-metal contact. Do not paint the anode. Current references also indicate that mounting hardware may not be included, so check your existing fasteners before starting the job.

Parts Desk Insight
Dogbone anodes are simple parts, but they protect very expensive sterndrive components. One useful fact is that this anode has stayed in circulation across older Volvo Penta drive families for a long time, which is why it shows up under several cross-reference numbers. That long service history makes serial-number verification more important than going by shape alone.
