That's normal. The cooling water is dumped into the exhaust at the end of
the riser.

I have a '94 5.7 L Mercruise in my boat. Recently while running on the
hose when flushing i noticed steam coming from the exhaust on the prop and
the exhaust on the bottom of the outdrive. It wasn't a tremendous amount
but never noticed it before. Any basic suggestions to troubleshoot ?

THanks!
