Big Al, The hole lets you know when the seal is going bad, so if it leaks out that hole you better order a pump A.S.A.P. ~Hit-man~ (Cars are the same way)

Big Al
Because I have never replaced the YZ seal,
I am not sure if YZ's are the same as CR's, but on certain CR's you can fix the "peep hole " leak buy simply replacing the outer water seal, that is just behind the impeller.

do you need to change the entire pump if the seal (s) are bad ?

Mine did that last winter when I went out for a ride.
I had left the bike towards the front of the garage near the door where it is noticebly colder. I think this is what caused it.
the seal must have gotten real cold or maybe the cold air dried it out.
I was out riding and thought i had cracked something. It was the only time i did not have my manual in my toolbox............figures!
got home and ordered the $2.13 part and also the oring gasket was about$4 which i replaced also.
but anyway i was happy it was only $6 instead of $600
Super simple too.
just make sure you put it in square.
I used just a little tiny scrwdrvr to get it out very carefully.
I used a socket that was the right size to push it into place.

.It is actually called the WEEP HOLE

That's not thunder ridin' your BUTT .........
It's a whole Damn HURRICANE!!!!!!
