2003 GTX 4tec, IMPELLER and Wear ring?
I took my ride plate off today cause it need some work, so I got to looking at my wear ring gap between the impeller and the wear ring and it looks as if I can fit a coin between the two.
Is that bad? What would happen if I didnt replace it?

yes that is bad, you should barely be able to slide a peice of paper in between!!!!!
there is a spec, but basically if you can see light from around the impeller or it is worn unevenly or damaged/gouged, the wear ring should be replaced.
also look at the impeller for dings or bends.
the 2003 OEM pump housing was plastic, it warped under heavy loading, so many people upgraded to a 2004 and up pump. you can usually find a used pump for 200-300 dollars. then you just need to replace the wear ring and put in your 2003 impeller and you are all set up.
do a board search on plastic pump and there is tons of info.
i have a 2003 GTX SC and i ahve done the upgrade.
if you dont want to upgrade at this time at least you can do the wear ring flip trick!!!!
look up "flip wear ring"!!!
how is your cooliant leak and runnig problems??

how can i tell for sure what year my ski is, I was told it was a 2004 but i looked at the hid and didnt see any 4 in it what so ever, but there was a cuple 3s, i dont know what digit is the year in HID, Only VID.
And how could it posibly wear out? just water is going though?
Also I got the running problem fixed, now I have to replace my ride plate cover and gasket cause its badly corroded. thats where i was loseing the coolant.

ur vin will start with either ZZN tunil 2004... or YDV from 2005 to current
so for example... ZZN12345A303
the A means first month of the year... January
the next digit is year of manufacture -2003
the last two digits are model year - 2003
u can have this for example....
L means december for 12th month of the year and 12th letter of the alphabet
7 means built in 2007
08 means it's an 08 model machine

Yeah mine starts with ZZN, I need to find this wear ring.

if the pump housing is plastic, it flex's when under high pressure, and the flex wears the wear ring out prematurely.
