Default Thru hull water pick up

My boat is starving for water. 575 Engine running hot all new pumps, probably due to transom suction hose. Any thoughts pros/cons?

When your engine is running hot what is your water pressure ?

What kind of water do you run in, ie brackish, silt? Do you have a sea or sand strainer? Flush motor periodically?

My engine builder says absolutely put the key through transom or through haul water pick up on the guy that works on the boat other than the engine says no use the normal pick up through the transom assembly and I’ll drive not sure which way to go

Something does not sound right , I have my pick-ups mounted on the transom and I have 15 lbs of water pressure to the engines and mine do not run hot at all , you might have a water volume problem .

Did you add the sea strainers? if so do you still have the screens in the bottom of the offshore pickups? I was told if you add sea strainers you should remove the screen/grill on the bottom of the pickup.

You know your water pressure but whats your water flow? Remember water pressure can be had without hardly any water flowing and this would be a potential for overheat condition.

It may be a long shot but I had sand granuals jam up the nylon check balls holding them open in the thermostat housing. Part #9. Take your hoses off both sides and make sure they are not hung open,
