Anodes

Do anodes actual eat away like a block of salt, or do they get "used up" but still appear to be okay? I have a 1991 Evinrude 60 HP. Bought used. Runs fine. Wondering if anodes need changed. Look good, but...have they ever been changed?
 
When you install the new ones as Chris recommended, weigh them and write it down. When they lose about 50% of their weight, change them again.

Also, be sure they have a good clean, oil-free mating surface to the engine. On the big Honda's, there is actually a small cable that runs from one of the bolts for the main anode to a bolt on the stern bracket in order to assure better contact and protection.
 
Yeah, you're better off safe than sorry... anodes are generally not that expensive. Just makes sure you get the right kind for where you'll be boating (zinc, aluminum, or magnesium etc.)
