    Serial number

    Can anyone tell me the location of the serial number on a
    1993 XR6 150 hp motor. I've looked everywhere I can think it would be. Thanks in advance.

    The original location is on the right (starboard) side of the mounting bracket on a label. If that is missing there might be a Welch plug (round silver disk about the size of a half dollar) on the block, usually near the top with it punched on it.
