Water out back of engine low

hello everyone. 


I am am a proud new owner of a new 40 etec. Just took boat out for short test run today and had only one slight concern. Water flowing out of engine in back seems weak. What I mean by that is my old mid 70s merc; water shot out at a pretty good pressure and more so at faster speeds. New Etec water didn't dribble out, but little change with speed and hardly seems to come out with any great pressure

so what's normal?  I checked owners manual & I would say they draw it like it come out! Ha

thanks guys!

The 2, 3, 4 cylinder and the  60° V4-V6 engines utilize a  high-volume low- pressure water tell-tale. It has a gentle flow out the back of the engine through a 3/8" diameter tube as part of the EMM and fuel cooling system.


The big block motors are of a different design with a small-diameter high-pressure tell-tale that you may be familar with that sprays a strong but narrow stream of water.

Thanks for the response. Kinda of what I was assuming, but didn't want to take any chances. Going to check with Duanes Marine in Virginia just to be certain. They have been great this far and don't wish to take chances up in Voyagers over memorial weekend
