Martyr CMT-433580Z is a zinc long bar trim/tilt anode designed for OMC, Johnson, and Evinrude power trim and tilt bracket applications. This is a bolt-on bracket/transom-style sacrificial anode used to help protect trim and tilt components and nearby bracket hardware from galvanic corrosion in saltwater service. Zinc material is intended for saltwater use.
Key Features
- Zinc long bar trim/tilt anode
- Bolt-on bracket/transom-style design
- Used on power trim and tilt models
- Approximate dimensions listed by sellers: 6.86" length, 1.4" width, 0.8" thickness
- Mounting spec commonly listed as 5/16"-18
Engine Compatibility
Commonly listed for Johnson and Evinrude outboards in the 50/60 HP through 225/300 HP range on 1991-and-newer power trim and tilt bracket applications, but listing details vary by seller. Fitment should be confirmed by the existing anode shape, bracket style, hole spacing, and mounting hardware before ordering.
Serial Number Fitment Notice
Fitment should be confirmed by the installed trim/tilt bracket anode pattern and application rather than by engine family alone. Match the existing long bar profile, overall dimensions, mounting hole arrangement, and bracket location before purchase.
When This Part Needs Replacement
Replace when the zinc is heavily wasted, cracked, loose, or no longer maintaining proper protective mass. Trim and tilt bracket anodes should be inspected regularly because they protect exposed bracket components that see constant water contact in service.
Installation Notes
Install on clean mounting surfaces so the anode can maintain proper electrical contact. Confirm the replacement matches the original long bar trim/tilt bracket pattern before installation. Zinc is the correct material choice for saltwater applications.

Parts Desk Insight
This style of anode is pattern-based more than engine-name-based. On OMC trim and tilt applications, the safest match is the existing long bar shape plus the bracket mounting pattern. Even when horsepower ranges overlap, confirming the installed anode profile is the best way to avoid ordering the wrong bracket anode.
