Short life of heat exchanger zink

We get only 6 months from the heat exchanger zink on our Perkins 107. I added a ground wire from the exchanger to the boats zink but there was no improvement. We had a exchanger failure 6 months ago that I suspect was related.

Probably was related since most manufacturers recommend you change that zinc monthly not every six months.

Re: Short life of heat exchanger zink

Most probably do not replace their zincs monthly but more likely start the season with a fresh one. Perhaps you should check yours monthly for a while and see how fast a fresh one is wasting away. Once it is two thirds gone, may be time for a new one. Six months would be a long time for a zinc I thinc.
