Description
Tecnoseal Zinc Saildrive Anode for Yanmar | Boat Supply Store
Prevent galvanic corrosion in saltwater environments with this specialized Tecnoseal zinc split collar anode. Engineered as a direct replacement for Yanmar SD20, SD25, SD30, SD31, SD40, SD50, and SD60 saildrives, it provides essential sacrificial protection. This anode utilizes the electrochemical properties of zinc, which is preferentially corroded, safeguarding the more valuable components of your saildrive and propeller from deterioration in marine conditions. The split collar design facilitates a simpler installation process compared to solid anode designs.

Common Concerns Answered
Are fittings included with this anode?
No, fittings are not included with this Tecnoseal anode and must be purchased separately. This ensures you can use the specific hardware required for your installation.
How do I ensure this anode is compatible with my specific Yanmar saildrive?
Verify your saildrive model against the list: SD20, SD25, SD30, SD31, SD40, SD50, or SD60. This anode is designed as a direct replacement for these specific Yanmar designations.
What makes this anode better than a solid anode?
The split collar design of this Tecnoseal anode offers a distinct advantage in installation ease compared to solid collars, simplifying maintenance and replacement procedures.
Frequently Asked Questions
What is a split collar anode?
A split collar anode is a sacrificial anode designed with a break or seam, allowing it to be easily fitted around existing drive components without needing to disassemble them entirely. It fastens securely once in place.
Why is zinc used for anodes in saltwater?
Zinc is utilized for anodes in saltwater because it is more electrochemically active than the metals in your saildrive and propeller. This means the zinc will corrode preferentially, acting as a sacrificial element to protect the submerged metals from galvanic corrosion.
Which Yanmar Saildrive models does this anode fit?
This Tecnoseal zinc split collar anode is specifically designed to fit Yanmar SD20, SD25, SD30, SD31, SD40, SD50, and SD60 saildrive models.
Do I need to purchase fittings separately for this anode?
Yes, fittings such as bolts and plate adaptors are not included with this anode and must be acquired separately if not already possessed. Tecnoseal offers compatible plate adaptors (PLAC-1) and bolt kits (KIT01305-1).
What is the original Yanmar part number for this anode?
This Tecnoseal zinc split collar anode replaces the original Yanmar part number 196440-026600.
