Where is the discharge hole for the waterpump?

See that big hole at the rear portion of the engine a little ways below the powerhead? That's a exhaust relief hole BUT it is also a water exit. A great deal of water should exit there with quite a bit of force.

The other water exit is just above the propeller.
