The rest of this job is very easy, as it is almost a reverse of the breakdown. Begin by installing your new prop onto the prop shaft. Make sure you use plenty of thread lock, and crank it down as hard as you can. Your prop is the last piece you want to lose on the lake! Now replace the cone at the rear of the pump stator assembly and tighten it back on. It wouldn't hurt to place some grease on the exposed bearing surfaces before you re-install the cone.
Before you can put the assembly into your ski, you have to install the new drive shaft o-ring that comes with your prop. Liberally grease this with marine grade grease, and slide it onto the drive shaft. You should easily identify its resting position as a recessed point on the shaft.
Now mate the prop stator up to the pump housing. It would probably be easier to install this with two people, one to hold the drive shaft, and the other to place the pump back in. Make sure you have the stator assembly properly aligned. (There are tabs that should lock in place when mated correctly) When everything is aligned correctly, the pump stator assembly will slide in and lock. Don't worry, you can let go, it won't fall out. (Well, you shouldn't bump the ski at least!)
