Hello, I have a 1969 mercury 1000 and am wandering if its harmful to the engine if i run the water hose to it while the engine isnt running. I cant get water to come out of the pee hole and im trying to check the hose leading to the hole for dirt.
Actually, this can be extremely harmful!! If you're not getting a tell-tale there's a good possibility you need to replace your water pump. Hooking up the rabbit ears wth a worn out water pump does absolutely nothing except waste water. Your motor could easily burn up after only a few minutes if not cooled adequately. Hope this didn't get to you too late. Good luck!
