Zinc Version – Please Check Before Ordering
This listing is specifically for the ZINC version of the anode.
Please check which type of sacrificial anode you require before ordering.
SSI Marine also stocks an ALUMINIUM version for these applications, which is listed separately.
Important – Please Check Compatibility
Please do not order by horsepower or appearance alone.
Before purchasing, please check:
- Exact engine model
- Engine year
- Engine serial number
- Existing anode
- Original Yamaha part number
- Required anode material – Zinc or Aluminium
If the anode looks the same as yours, this does not always mean it is the correct one for your outboard.
If you are unsure, please send us your engine model and serial number before purchasing and our technical team will be happy to help.
