August 28, 2018

ANODE ACADEMY – WEEK #1 – CORROSION – What does it look like under your boat?

Corrosion occurs in all types of water, salt, brackish and fresh. As a boat owner, it’s important to be aware that any type of metal that is in contact with water is subject to corrosion.

Below on the pictures, you’ll see various types of corrosion unique to each different metal. The rate of corrosion may be affected by the type of water, the type of metal and electrical activity around your boat.

  • Propeller – Bronze (most common) followed by Stainless Steel and Aluminum
  • Shaft – Stainless Steel
  • Rudder – Bronze or Stainless Steel
  • Trim Tabs – Stainless Steel
  • Hull – Fiberglass (not subject to corrosion), Steel, Aluminum, and Wood (Fasteners are highly susceptible to corrosion).

Stay tuned next week to learn more about how “GALVANIC CORROSION” and “ELECTROLYTIC CORROSION” occur.
