winterize

[tbirdkidd]

I am winterizing my Mercruiser 5.7 2004 motor and cannot find the starboard side brass plug to let the water out, I have looked all around the starter above the oil pan and it is not in the same place as the port side. Can anyone tell me where to find it

Re: winterize

I'ts probably in the Y connector with the knock sensor near the starter. Hard to say for sure without a SN, or even knowing if you are carbed or EFI. Merc doesn't go by year. Only 98 and newer.
