Holes in outboard cowling

A 2013 4 stroke 25hp Yamaha outboard has 3 holes in front side on
The cowling between the power head and water pump. Two of holes are
About 15" above the water pump spaced about 2" apart. The third hole is
Near the top of this cowling.
At idle water flows out of lowest hole. Is this normal?
What is the purpose of the three holes ?
Thanks for all that answer
