Is anode replacement the right service?

Likely suitable if:

  • Existing anodes are visibly depleted or missing.
  • You are lifting the boat for seasonal maintenance.
  • You are already planning antifouling or prop cleaning.
  • You have changed water types (e.g., salt to fresh) and need different anodes.

May need another service if:

  • You need a full hull clean and coating (Antifouling).
  • The prop is heavily fouled with barnacles (Prop and Shaft Cleaning).
  • You need advanced electrical bonding diagnostics.
Alternatives: Antifouling | Prop & Shaft Cleaning

What Anode Replacement Actually Does

Anodes are sacrificial metals attached to the hull and running gear. They corrode intentionally to protect more valuable underwater metals (like the propeller and shaft) from galvanic corrosion.

  • Anodes are a separate below-waterline maintenance item from antifouling.
  • They must be matched to the water type (salt, fresh, brackish).
  • They are normally checked while the boat is lifted ashore.

Signs You May Need This Service

  • Anodes are visibly depleted (more than 50% worn).
  • Anodes are missing completely.
  • You are changing the environment where the boat is kept.
  • It is time for the annual lift-out and maintenance.

Before confirming the right approach, Watts Marine should check:

  • Boat length, type, and location.
  • Whether the boat is ashore.
  • The water type the boat will be moored in.
  • Condition of existing anodes (if visible).

Service FAQs

What do boat anodes do?

They act as sacrificial metal, corroding away so that your expensive underwater gear (like props and shafts) does not corrode.

How often should anodes be replaced?

They should be visually inspected annually when the boat is lifted. Replace them when they are about 50% depleted.

Do I need zinc, aluminum, or magnesium anodes?

Zinc is traditional for salt water, Aluminum for brackish/salt, and Magnesium is exclusively for fresh water.

Do you cover Gillingham, Chatham and Medway?

Yes, we handle enquiries across these areas depending on boat location and access.
