That's normal. The cooling water is dumped into the exhaust. That's how
the exhaust is kept cool enough to run through rubber hoses and bellows.

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!
