Opinions are appreciated~the schematic starts with a one and one quarter inch pickup~to the sea strainer~to the pump~to a collector for both pump outlets~to the power steering cooler~to the transmission bell housing cooler~to a thirty two o eight caterpillar engine cooler~to the engine oil and transmission thermostats ~to a collector that splits the flow between both inlets on the Eickert crossover~out the one and one quarter inch outlets in the BDS intakes~to the CMI low cat headers~to dry tail pipes with a dump~the steam ports at the back of the intake go to the back of the header water log~we do not have inter coolers~I think I like the extra insurance from the dual impellers ~excess pressure or spikes will be dumped overboard with a pressure relief valve after the coolers but before the thermostats

A suggestion of having the pressure relief valve at the sea strainer instead. On my boat there is a seperate fitting on the strainer with a relief valve that will dump out the stern.

If one pump looses an impeller you're gonna have to stop because it may clogg a cooler,just a thought...

I'm running the same pump as yours with similar routing, except using the bell housing coolers for engine and trans. Like Brad's, the sea strainers have a pressure relief valve at the top for pressure spikes. The spikes and steam ports dump over the side.
