Engine water pump

I have a 1988 37’ with twin 454 engines and I’m trying to fine a reverse rotation water circulation pump, not the raw water impeller, I found this https://bpi.ebasicpower.com/shop/index. ... s_id=11607

This has a flexible impeller that can be used cow or ccw rotation, anyone know of this one? Or where can I find a replacement? I’ve looked at several sites and most are standard rotation pumps.

The standard circulation pump work either direction. Mercruiser only sells one direction for both motors.
