    http://partsfinder.onlinemicrofiche....=13&A=169&B=25

    300 pump
    http://partsfinder.onlinemicrofiche....=13&A=191&B=25


    only thing i see different is that i dont have the nut.... anyway wish i took the pump out first, now that i have this out i cant believe how simple it would of been to thread my own shaft...

    That's another difference.

    um its 2 dual row bearings towards the hull and one by the impeller. looks identical to the 300x setup minus nut, i am going to machine and thread my old shaft to fit the nut and re install the original stuff the ski came with.

    gonna keep the new stuff as a spare and i think i am going to upgrade to a 260 next year anyway so ill have everything i need to upgrade that pump.

    are you sure it has twin bearings up front? it doesnt look like it to me how can you see the front bearing has black seals.
    up front there is a circlip which holds the black seals in place in the centre of the seals is a spacer and the bearing or bearings if fitted press in from the other end. hope you arent thinking the seals are yhe front bearing thats all
    like we have said 1000 times just mod your original shaft turn space for the extra bearing then turn the thread on the rear.

    it has two bearings that are and inch wide each,and look similar to the bearings i used to do in my rear carrier for my race quad.

    Front Bearing reads Koyo 6303R-6RD P/No 920453740

    well as long as there are two you are right then just sounded to me you were confusing the spacer and seals as the second bearing in the front. still dont know how you know the front bearing has black seals because you cant see it without removing the second front bearing the one pictured with the brown seals the other is behind hidden from the seals and spacer !!! btw i think the front bearings are only 19mm wide and the spacer would be 25mm. i seriously dont think you have the dual front bearings in that pump.

    Agree. Take the the seals out and look again. That shaft doesn't look modded.

    better still push the bearings out with the spacer then turn it over and push the seals out that way you wont damage the seals and you can use them again

    you guys are right i mistook the seal for bearing seal. anyway the bearing seal reads Koyo 6303R-6RD

    what spacer? it goes seals, 2 bearings and that is. bearing are back to back, now that i am looking at it looks like the front bearing is actually . front bearing is 25mm, inner is 19mm according to caliper.
