Circulating pump v. Raw water pump

[ers906]

I am planning on putting a new strainer on, just need to pick up the parts. I figure replace what I can and simplify (without the FlushPro). Since I put between 200-300 hours on the boat a year, I tend to go through 2-3 impellers and 5-6 oil changes each year/season (keep in mind the AZ season consists of early March to mid-late November). Try to minimize anywhere problems can occur. Thanks all of you for all of your help

How did you know when you needed to replace the circulation pump?

seal started to go and I started to get water out of the weep hole. still worked fine, just didn't like the small water leak.
