    Merc. 200 EFI

    On my 93 Mercury 200 EFI, it runs great but the
    ”pee water” is so hot I can’t hold my hand under it.
    is that a sine of needing a new water pump?

    The pee stream comes from the thermostats, which open at 143 degrees, so that would be scalding hot, it’s normal and don’t do it.

    Wow, that is really good to know. My service guy told me I needed to change it.
    Glad I ask.

    IT’s recommended to service the pump once a year or every 100 hours, which ever comes first. If you don’t know when the pump was last serviced you probably think of having it done for safety sake.
