Anode Replacement Checklist for UK Boaters (Season Start and Winter Lay-Up)
Anode checks are one of the simplest maintenance jobs that can prevent some of the most expensive corrosion problems. Use this UK-focused checklist at the start of the season and again at winter lay-up.
Season start checklist (spring)
-
Inspect all anodes (drive, trim tabs, shaft, fittings)
-
Replace any anode around 50% consumed
-
Check for uneven wear (signals bonding or electrical issues)
-
Confirm correct material for your water type
-
Ensure anodes are tight and have clean contact surfaces
-
Do not paint anodes
-
If you boat in marinas, monitor wear early in the season
Mid-season quick checks
-
Quick visual inspection every few months
-
Look for loose anodes or unusual pitting
-
If wear rate changes suddenly, investigate why
Winter lay-up checklist (end of season)
-
Inspect anode wear pattern and note it for next year
-
Replace heavily worn anodes so you do not forget in spring
-
Photograph fitment and part numbers for easy ordering
-
Check for corrosion on underwater metals (don’t ignore it)
-
If anodes vanished quickly, consider an electrical inspection before next season
Common mistakes to avoid
-
Using magnesium in saltwater
-
Leaving half-missing anodes until “next trip”
-
Painting over anodes
-
Ignoring rapid wear in one specific marina
-
Mixing materials across the same protected system
What to do next
Treat this checklist as a routine. It saves money, reduces stress, and keeps your underwater gear protected.
