525EFI Water Pressure Concerns
New to me boat with 525's. Starboard water pressure gauge is reading 15-20psi while the port will peg the gauge well past 35psi. We did replace a broken plastic Perko flush/check valve for one of these https://www.supplyhouse.com/sh/contr...oduct_id=40615
Not sure what's going on here. Thoughts?

I usually see 25-30psi with dual water pickup drives and 525s. Even with strainers I still back flush the coolers individually and am always shocked what gets thru. Oil, PS and fuel coolers allow for many areas to form a blockage

Service manual says max water psi is 43. I routinely see over that with no problems and I've talked with others who see over 50 with no problem. I'd be more concerned about the low pressure engine.
