There are 100+ anodes and anode fittings in this category, each listed by part number with the motors it fits. That includes anodes for Evinrude motors, which BRP stopped building in 2020, and older Johnson and OMC models.
Most of the range is made up of zinc anodes for boats and outboards running in salt water, and most product names state the material. Where one doesn’t, check the product page or ask us.
When choosing a sacrificial anode, boat owners should go by the water the boat spends most of its time in. If it moves between water types, inspect the anodes more often and change them as needed.
Don’t mix zinc and aluminium on the same outboard or sterndrive. The aluminium anodes end up trying to protect the zinc. If you’re changing alloy, change every anode at once.
Anode wear tells you how hard corrosion is working on the motor, so read it before you replace it.
Wearing faster than usual. Mercury’s corrosion guidance names the conditions that drive it: time sitting in the water, a connection to shore power, a stainless steel propeller, and warmer water, which is more conductive. A boat on a warm Queensland mooring, plugged into shore power and running a stainless prop, has all four working against it. Mercury also warns that a broken bonding wire, or one left disconnected after a service, accelerates galvanic corrosion.
Not wearing at all. Mercury points out that a boat motor anode which never corrodes is a bad sign, not a good one. Check for paint on the anode, a mounting surface that isn’t clean and free of paint, a disconnected bond, or a surface film. Mercury says a stiff brush will remove the film. The last thing to check is the wrong alloy for the water, such as zinc on a boat kept in fresh water.
Mercury lists the gearcase, transom bracket and trim rams as the usual places to find a boat motor anode. A full check covers:
A sacrificial anode on a boat gives less protection as it dissolves, so Mercury’s guideline is to replace anodes when they are 50 percent consumed. Inspect them often if you run in salt water, and plan on replacing them at least once a year.
If the old anode is too worn to read, match from the motor: model and serial number first, then the parts diagram. Our Yamaha serial number lookup and Mercury serial number guide show where to find both and how to read them.
Check the year range on the listing as well. Yamaha anode 67F-11325-00 is listed for 1999 to 2004 motors and 67F-11325-01 for 2010 on, while 68V-11325-01 covers 2004 to 2006 and 68V-11325-02 covers 2007 to 2009.
When they are about half consumed, which is Mercury’s guideline. Inspect them often if you run in salt water, and replace them at least once a year.
Yes, in salt or brackish water, as long as you change every anode on the motor at the same time. Don’t mix the two alloys.
In some water conditions anodes build up a surface film that stops them working, and Mercury recommends removing it with a stiff brush. If the boat lives in fresh water, zinc is the wrong alloy.
Common causes are long periods in the water, shore power, a stainless prop and warm water. A broken bonding wire also accelerates corrosion, so check the bonding if wear has suddenly increased.
