Unless you do tank testing to determine  the exact water flow at the stern 
at varying speeds,  it would be hard to  get the location exactly right.  On 
the big boats that I have been on  they vented the exhaust down  and out 
from the very bottom of the boat.  There was a bypass for idling at the dock 
that exited near the stern at the water line.

I once tried to incorporate this design concept into a 50 footer  but it was 
rather crowded  with  the required wet exhaust pipes plus a bypass.  My 
mentor, Mike Harling  expressd the opinion that  it was not practical for 
smaller than hulls of about 70 feet.
