Mercruiser 350MPI
I just purchased a 2003 Sea Ray 320DA with Mercruiser 350MPI engines, V drives. Engines have a OEM flush kit with a label that states engine must be running when you flush system. My question is do you shut the tru haul valve, then turn on fresh water, and then start engine to flush. A engine manual did not come with boat.
