I was riding my ski today and i hit the gas and it made a pop and wouldnt move and started taking on water so i got pulled to shore to find that some type of bearing or something inbetween the pto and impeller gave out grease everywhere motor runs fine so i am very happy because its brand new but what is the problem. I started to take external pump parts off to see if i could take impeller off and pull out the shaft but after i take off small cone where gear lube is i cant get the square shaft to turn any ideas i am guessing those are reverse threads onthere HELP me please....
