You have to get the water from the foot to the powerhead with this tube.

It would help to know what kind of setup you're talking about. Assuming Mercruiser, I'd say it's Ok. The tubes job is to get the exhaust gases directed thru the prop hub to help in starting from a dead stop. It aeroates the prop to let the rpms come up a bit. The early engines used an exhaust boot. It was discovered that V8 engines would cause the boot to swell and get abraided and fail. Thus the tube was introduced. Hope this helps.
