Zincs

[wfujewell]

I need to replace the teardrop and shaft zincs on my boat every season as they are just about 99% gone and the larger hull anodes every three seasons. Is this rate of wear excessive?

I wind up having to replace my shaft and tab zincs about twice a year and the big anode about every other year

Seems to be pretty common in my marina - I hate seeing power cords in the water...
