    Moved-Engine not peeing much

    Moving my thread to this section after being asked to. Serial Number for my engine is 0G000085. So I have a 1994 Mariner 200hp and I noticed that when I was on the lake last, it was not peeing out water consistently or very strong for that matter. I went ahead and disconnected the hoses that follow the intake through the engine and blew them out with an air compressor but nothing was lodged in there. I also had my impeller replaced early this year and I am trying to figure out what other options I could take to diagnose what my issue is. Thanks all!

    I would start with a whole pump change including all three gaskets. Bad gaskets could be your problem. Do you have a pressure gauge?

    ALWAYS start at the SOURCE: The Water Pump. Complete pump kit is 96148A8.

    Also, keep in mind that the telltale comes from the Thermostats. There may be little (or no) water until the thermostats open, and stream may come and go as they open and close.

    Stream will also be SCALDING hot.
