Tom-N-Jerry’s Boats – Protecting Your Aluminum Boat from Salt Water Corrosion

The staff at Tom-N-Jerry’s Boat Center in Mount Vernon, Washington specialize in aluminum boats and know that they can sometimes get salt oxidation marks on them, which can quickly lead to galvanic corrosion. If you own an aluminum boat, there are several things you can do to help prevent your boat from becoming a victim of galvanized corrosion.

  • Don’t mix metals. If you are going to mix metals be sure to use metals that are close to each other in the galvanic series.
  • The bolts on your boat should be less active than fittings. Bolts are small so any loss of metal is more serious.
  • Do whatever you can to electrically isolate fittings from each other. This is important to do even on small craft.
  • Anodes should be securely fastened. Make sure that there is a firm contact with the metal that needs to be protected.
  • When it comes to anodes, you never want to paint them. The metal that it is fastened to also needs to be free of paint, scale, and dirt.
  • Never allow an impressed current voltage to exceed 1,300 millivolts when protecting aluminum.
  • Always repair any scratches and paint chips that expose bare metal.
  • Don’t use lubricants that contain graphite aboard a boat that is made from aluminum.
  • Wash down the boat with fresh water after every use to remove any salt that has built-up.

Protect your aluminum boat and equipment from the rigors of the marine environment. If you have questions or concerns regarding your aluminum boat, contact the knowledgeable staff at Tom-N-Jerrys Boats, specialists in aluminum boats.
