pulled my jet pump off and the drive shaft came with it. I pulled it off of the jet pump assembly and placed it back into the hull carrier.
my question is, should I be able to turn that chaff by hand and see it turn up by the engine pto?
Yes, but it might be difficult with the spark plugs in.
Typically when you pull that rear driveshaft the rear couple will fall down and disengage from the middle driveshaft.
