    Check up in the intake grate as well as into the pump. Maybe something got sucked up and made its way into the impeller. Take a flash light and look into the pump. You may be able to see the wear ring and the condition of it. Should be only 1-2 mm gap between the impeller and wear ring.

    Check the pump oil ! make sure the O ring sealed.Sounds just like the pump is gone and it seized up from heat,if thats the case it will need a rebuild with a prop shaft (not driveshaft) jmo goodluck

    If The oil you replace in the pump leak out because of a faulty seal or the o ring on the cone got broken. This might be what happen. Me my self have cross thread the filler screw and water had gotten into mine. But I had cot it in time. I never got any whining. Just had to rebuild the pump. That why it a good idea to replace the oil in the pump ones a year even if it dint need it. This work for me any way. But some say if it not broke don't fix it.

    Ok? but you had to remove the pump cone and replace the oil at that time,....soooo did you make sure the pump oil didn't leak out? or did you even replace the oil?

    The bearing and seal and o ring should all be replace. If the shaft looks good it might be ok. But look at the flat suface where the bearing rides and make sure it not burnt or pitted. Sorry about the hassle you had to go threw. The water got in my filler screw because I cross thread it . So I bought a new cone too. thread lock it and I dab a little silacone over it. Just in case. But it will most likly come off in a few rides. good luck.
