Hardin Marine 620-700 water plumbing
#1
I'm installing a Harden Marine cooler and have a question regarding the raw water plumbing. The old oil cooler was mounted on the engine bell housing, the Harden cooler is too big and needs to be relocated to the stringer.
Is it possible to run the raw water from the inlet through the strainer to the cooler then the raw water pump instead of inlet to strainer, pump, cooler as it was with the old system? Basically running on the suction side versus the pressure side of the pump?
If the answer is do not run on the suction side, why??

Recieved the following reply from Hardin Marine, thanks Jeff.
The pump will have work harder to suck water thru the oil cooler. 99% of the industry goes to the oil cooler after the pump.
