You need to Tee into the last point of salt water injection prior to the water entering the exhaust mixer/elbow.

Would advice to put small seacocks inline to prevent any chance of seawater returning up into the exhaust system. Shouldn’t happen if you have anti-syphon valves on your cooling system, but seacocks provide extra safety should a hose fail, or if you are to leave your boat for any length of time you can close them. (as you should do to all seacocks when leaving the boat unattended)
