1996 volvo penta 5.0 gipbycce. She hasn't run in over a decade. I've been working/learning on it for the past year. Getting ready to drop it back in the hole and fire it up. I have the outdrive off so a test tank won't work. I have somewhat low water pressure if I were to put a hose on the intake side of the raw water pump. I could also fill up a 55 gallon drum and let the same hose suck water out of the drum. Any thoughts on which way would be better? Weak water pressure direct from a hose or let the pump draw water from a large barrel? Any idea of what the flow rate is on the raw water pump at idle? Thanks in advance!
