There are 3 zincs (anodes) on your motor. Normally you only have to replace the one on the back of the gearcase just above the anti-ventilation plate every 1 to 3 years if used often in saltwater areas. One other is a large heavy bar shaped item underneath the trim and tilt unit and that one lasts for a very long time if everything is in good shape. The third is inside the gearcase exhaust area on the underside of the propshaft bearing housing. It normally doesn't require servicing and you have to remove the housing and bearing assembly for access.

 

If you are eroding the anodes very  quickly may you have have a problem with stray currents from either the boat's electrical system or from nearby electrical problems caused by neighboring boats or shore current from the dock's 120 volt system. Having copper based bottom paint will accelerate anode wear also. Another culprit is the use of automotive portable battery chargers while a boat is in the water.

 

If severe, you may have to enlist the services of a marine electrician to check the environment for leaking electricity. Look for someone ABYC certified.
