I believe that the water tell tale discharge hole is actually in the rear water jacket cover which looks like a cylinder head. Look at the bottom of the cover and you should see a small hole drilled into the water jacket cover and it is angled to the starboard side. Use a drill and clean out the hole as they get plugged up with sand and grit. I am sure I will be staked out face down on the ground over a fire ant hill if I am wrong.
