Default 525 EFI circulating pump

Hi,
I was wondering if anyone has successfully used an alternative circulating pump on the 525 EFI motor? The factory part number is 811573A04 available for around $400. There are several pumps available that cross-over to the 811573 pump, but those were primarily used on the earlier non-closed cooled motors. Thanx!

I will check later for you guys I possible have them in stock for 195 each shipped to your door. I have all my water circ pumps made here in the USA. For all Marine engines including the LS and a few Ford marine versions as well.. Mercruiser last year started using the exact place as to where I get my pumps made. These are all marine rated water circ pumps. I have to check and see what I have left currently. THANKS
