Aluminum Streamline Shaft Anode – 1-3/4" | CMT-X08AL
Protect your propeller shaft from galvanic corrosion with this streamline-profile aluminum sacrificial anode. The hydrodynamic teardrop shape reduces drag compared to standard collar anodes, making it a smart choice for performance-conscious boaters who don’t want to sacrifice protection for speed. Sized for 1-3/4" shafts and secured with stainless steel Allen screws for a solid, rattle-free fit.
Key Features
- Aluminum alloy construction — correct choice for brackish water and freshwater environments
- Streamline (teardrop) profile reduces underwater drag versus round collar anodes
- Fits 1-3/4" propeller shafts
- Secured with stainless steel Allen screws — included
- Sacrificial protection — corrodes preferentially to protect shaft, cutlass bearing area, and running gear
- Split-collar design for easy installation without removing the propeller
Parts Desk Insights
Best use case: The CMT-X08AL is the right anode when your vessel operates primarily in brackish or freshwater — aluminum anodes outperform zinc in low-salinity conditions and are the preferred choice for Great Lakes, coastal inlets, and river boating. The streamline profile is especially well-suited to sailboats and powerboats where shaft drag matters. Replace when the anode has consumed approximately 50% of its mass — don’t wait until it’s gone. For smaller 1" shafts, see the Aluminum Streamline Shaft Anode 1" (CMT-X03AL). For saltwater applications where zinc is preferred, see the Zinc Streamline Shaft Anode 1-1/2" (CMT-X07). For magnesium anodes suited to freshwater-only use, see the Seachoice Magnesium Streamline Shaft Anodes.
