Yes that's it. On the wear ring. The pump you have listed above looks to be a plastic pump. I purchased three pumps all from ebay. Factory Aluminum fresh water. SBT also makes a new Aluminum pump. Not sure on the part number. Use the 267 000 046 part number for your search to cross reference. I will keep an eye out for you also. If I see one come up, I will send you a link.While doing research, I found this on SBT. It seems to show a pump from 2002-2017 130/155 will work. That expands the search quite a bit. Indicates it even fits several years of the jet boats.
Is this a typo or not? They claim their pump fits all these years.

On another note when you replaced the wear ring on the pump did you drill and replace the 4 little screws? That is what keeps the wear ring from spinning.
