Piping for Thermostat Housing needed

[raritan]

Can anybody help me with the correct hose routing for this housing. At the present time I have another housing without thermostat. It merely has two hoses that go to exhaust manifolds. Any help appreciated as always

Hi two top nipples go to manifolds, large one to water pump and the smaller of the larger ones is the sea water intake.
