I had a pair of 525 SC's with Super Chillers and ran them thru one strainer. The way I had it set up was with two thru hull pickups located each side of the center line of the pad, much like Monstaaa has suggested here, then two seperate lines plumbed up into the single strainer, then two seperate lines up to each of the intercoolers, then out and to thru hulls on each side of the boat. Worked great, as long as you go into the intercooler on it's low side and exit higher you'll never have any issues with traped air, and you can easily see if all is working by looking at the dumps on the side of the boat.
I would wonder about a screen in the pick-up itself, if it were to plug up you might have to take the boat out of the water to clear it, or at least unhook the hose to blow back thru it, and if it is below your water line that's not good. A good strainer should take care of itself in most conditions.

becarefull how far below the bottom you go as this will in fact slow you down from just the drag. plus slow you down from the disruption of the water in front of the props unless you have wide centers.
also call fountain for a price on the pickup. or maybe stainless marine

BKSAE, Pick ups can steal speed no doubt about it. Its a fine line to get enough for the motors and not dragging too much. It doesn't matter too much at 70, but 90 and up it matters a lot. Stepped bottoms get even more involved as you start to pass air into the cooling system and pressure gauges can't distinguish between air and water.

How much pressure do you have? Do you have pressure gauges on the chillers too? I didn't mean to discourage you. You just have to be aware of whats at happening. There are numerous ways to go about it. Are you just going to feed coolers with the new pick up? If so it wont have to be very large and one may do it.

BKSAE, I think 8 lbs through inter cooler is a good number to shot for. Where do you catch water for chiller now? Can you see the dump from the helm or reach from cockpit? If you pick up water for chillers with a pick up similar in size to pick up for motor, run through a strainer and split to coolers. Find a stainer that will bleed air off top and then trim pick up to get ideal pressure. Having not seen your set up understand I am making general suggestions. Avoid aluminum pieces in thru hull pick-ups and places you can't reach under motors.

Will a single -12 size pick-up feeding to a single strainer, like Lathams 9" tall one, then splitting to each chiller provide the 8 lbs you suggested. Thanks for the time and suggestions.
