I am in the Great White North in the deep freeze now. I plan on running the hoses in the spring when I get the boat out of winter storage.
I will let you know the results.

oh. Yeah I’ll have mine done in a couple weeks. Doing new fairing as well. I also added the link to my previous post about the Ts I’m swapping too for a cleaner look. Good luck when you get to it. Lol

So does anyone think I’ll need check valves for this?

I don't see any reason why you'd need any kind of check valve.

My water pressure has always been on the high side on 502mpi's. I have CMI's and may try something similar.

That’s what I was thinking. I’m sure at times some of the manifold to riser water will go intake but that would just warm up the engine faster. Only having one side done for first test proved very effective. So doing the other side should remedy all pressure issues.

So would someone please enlighten me as to why this setup would be better than a pressure relief valve between rwp and engine, dumping out a thru hull fitting.? Other than no additional thru hull

that would work also. My Strainers have a pressure relief port I just want less hoses and rigging in the bilge. This is an easy add without drilling or anything. If I had pressure issues from pickups/speeds I might go that route but this is engine based pressure. Rpm builds pressure not speed

Isn't engine based pressure based on rwp speed and amount of flow thru engine/exhaust .Just seems to me like it would be cleaner bleeding pressure under motor instead of a bunch of t;s and hose up top .
