Zinc's

How often do you change the zinc's on your outdrives? Our marine just told us every two years, previously we had gone much longer than that.

Look at them. If they are showing signs of deteriorating, replace them. I think I had 3 on my Mariah. When one was looking a little worse for wear, I had all replaced.

Zincs last a long time in fresh water. Actually, I think its something else in fresh water and zinc for salt. Somebody will chime in with better info. If your boat is on a trailer or valet, change may be rare.

Yeah this if you only boat on/in fresh washer. New boats don’t usually come with magnesium so you should check. If your boat has been in the water for a few years and they still look new they probably are not magnesium
