so first for the disclaimer.
This is a somewhat how to for an 07 launch 24 ssv. if you have no mechanical skill please do not try this as it is involved and you can f your boat up something good. read through this and take a look at the pics and if you want to give it a shot go for it and good luck. If not pay your dealer. yeah it sucks but its better then you messing it up and then having to pay even more to fix it.
First step:
when you hit something hard which i did take a look at the prop and assess the damage. obviously your prop will be bent but spin it and look at the end of the shaft where the cotter pin is and see if it spins true. if there is no wobble then your probably ok and only need to have your prop fixed. if not its new shaft time! Call your dealer and order the parts. tell them what kind of boat you have and order the shaft and v drive transfer case (transmission) seal. those should be the only two parts you'll need.
