which thrust washer to use?
 

I have a pair of 25" quicksilver mirage props...part #s 48-13707 and 48-13706, but no thrust washer to go with them. Can anyone tell me what part # washer to use...they are going on a pair of TRS drives and the props have a large diameter bore at the thrust washer end of the hub, by the way, the splines fit the TRS shafts and thelocking top washer fits properly. The mirage props on the boat now have a smaller diameter opening all the way down the shaft hole. Thanks for help
