Product Details

The CMP CMC05 is a limited clearance zinc sacrificial shaft collar anode engineered to provide reliable cathodic protection for propeller shafts in tight-clearance installations where standard collar anodes won't fit. Its low-profile, donut-style design makes it the ideal solution when space between the strut, keel, or hull and the propeller is restricted.

Manufactured from a high-purity zinc alloy that meets or exceeds US Military Specification MIL-A-18001K, this anode delivers consistent, predictable sacrificial corrosion performance — protecting your shaft, rudder, and associated hardware from galvanic corrosion in saltwater environments.

Key Features:

  • Salt water use only — zinc alloy formula optimized for saltwater and brackish water applications
  • Limited clearance design — low-profile collar fits where standard shaft anodes cannot
  • Interlocking two-piece halves — split design allows easy installation and removal around the shaft without disassembly
  • Stainless steel hardware included — bolt retainers keep fasteners in place for straightforward above or below waterline installation
  • Full circular shaft contact — 100% circumferential contact ensures maximum galvanic protection
  • Pressure die-cast construction — consistent alloy density and dimensional accuracy
  • MIL-A-18001K compliant — alloy manufactured to US Military Specification using high-purity metals

Specifications:

  • Inner Diameter (ID): 1-1/4" (32 mm)
  • Outer Diameter (OD): 2-1/2" (63 mm)
  • Height / Length: 1-1/4" (32 mm)
  • Material: Zinc Alloy
  • Water Type: Salt Water / Brackish Water Only
  • Hardware: Stainless Steel (included)

The CMC05 is part of the Martyr/CMP limited clearance collar anode series and is a direct-fit replacement for propeller shaft corrosion protection where clearance is at a premium. Replace when approximately half of the anode mass has been consumed to maintain effective protection.

Exactly as pictured and fast shipping

Everything came in really quick and packed well. Apparently I just ordered the wrong part.

Great price and easy to order. The website says free freight, when checking out it populated $9.99 shipping. I could not get this to go away. Still a great deal

Fast

Ordering my tire was a breeze. The website was easy to navigate and I received a delivery within the time frame I requested. I would recommend thmotorsports.com.
