Red gear oil pressure (engaged) - Answer-186-265
Jacket water temperature - Answer-140-185
Idle RPM - Answer-650
What does the raw water system cool? - Answer-Coolant, Air, Fuel, Red gear oil, Exhaust
How does coolant work? - Answer-Closed loop system that absorbs heat from the engine and its
components and releases that heat to the raw water system though a heat exchanger.
What kind of coolant - Answer-DDC Power Cool Plus Marine (50/50)
What does the jacket water cool? - Answer-Engine, Lube oil, Turbo
