    need info about pump bearings

    i just got a new pump housing complete with SS wear ring -- bearings --seals etc... now on my old pump housing to change the impeller i had to use a spline shaft for the impeller side and a allen wrench on the other side --- this one has a ( i don't know what its called ) round shaft coming out of the bearings with two flat spots for a wrench -- i have never seen this before ( but I'm still a novice to skis ) is this a new style ? a stronger bearing ? -- plus this housing is going to be oil bath -- attached are 2 pics of it -- some info would be a great help -- i just want to make sure i don't make a mistake

    That pump most likely had the Skat double or triple bearing mode done to it. Mine looks the same. Use 2-3 ounces of gear oil in it when you put it back together. I personally use the Sea Doo pump lube. You'll need to send it to Skat Trak to get it rebuilt.

    okay thanks -- my understanding is to run the SS wear ring its better to have the double or triple mod done is that right ?

    You will get less pump shaft flex with the double bearing mod, which will result in less prop flex also. I get very little wear on the prop and liner. I also have my pump rebuilt every year as a maintenance item. It's also easier to change the prop with the flat on the shaft vs. the prop tool and 12mm.
