For starters....
1.) remove the three hoses on the inside of the boat. (attached to the pump) if you do not do this first, you will forget and cause all kinds of problems for yourself!!!
2.) Remove the steering rod, 10mm bolt and nut.
3.) Remove 4 13mm bolts honding nozzle on. with this off you will have a much better view of the wear ring.
4.) Remove 4, 17mm bolts from the pump to hull. make sure you pull off all the lock washers and washers to ease pulling the pump.
5.) This is the tricky part.... Most shops gob all kinds of silicon on when replacing the pump and so it makes it a pain to pull it away from the hull.
You need to pull the pump away from the hull as streight as possible.
They sell a pump removal tool but I just made my own. i cut a length of 2x4 that I set across the rear of the ski and drilled 2 holes in it. I thread long 13 mm bolts with washers through the top two holes of the pump where the nozzle mounts. This pulls it away nicely with a butterfly impact.
6.) now you have your pump and impellor in your grubby hands, the next step is to remove the 3 8mm bolts on the cone. Make sure you have something to catch the oil and nose pluggs.... This stuff reaks to high heaven...
7.) after cleaning out the oil I place the pump impeller side up in a vice. (grabbing the flat end of the pump shaft in a vice)
8.) place impeller removal tool in the impeller and grab a 1/2" drive 3/4 sockett with a huge breaker bar. Twist it counterclockwise till it pops loose. (may take some pressure. I seriously use a 4 foot pipe on the end of my breaker bar and use a popping motion rather than smooth pressure.)
9.) now that you have the impeller out take your new wear ring and put it in the wifes freezer.
10.) back from the freezer you have to get the old one out of the pump. ( I have found the easiest way is to take a sawsall and cut a slit in the wear ring the full length of the pump) Be carefull only to cut the wear ring and not the pump.
11.) now take a large standard screwdriver and a hammer and tap the screwdriver gently between the wear ring and the pump all the way around to seperate them.
12.) Clean all the white corosion off the pump where you will be putting the new wear ring
13.) now after tackling this task go to the freezer and grab that wear ring. (dont dilly dally with it) get it to the garage and slide it in the pump. you may have to tap lightly with a rubber mallet. If it doesent slide in then you didnt clean the pump good enough. Repeat steps 9 and 12.....
14.) reinstall the impellor in the reverse order.
Note: it is very important not to pinch the thrust washer when re-installing the impellor shaft. thats why its a good idea to do it in a vice rather than on the ground sideways.
Once the impellor is tight you should have 1/8 - 1/4 inch play in the shaft back and fourth. if you dont start over and inspect your thrust washer you probably pinched it..
