Yeah. The prop came off no problem.
The thrust washer behind it was a bear to get off, though. Sprayed some PB Blaster penetrating oil on the splines and pried off using two screwdrivers on the back side of the thrust washer. A little tap tap & back/forth on the levers & it POP!-ed off. Fortunately, all of the prying didn't gall the aluminum gear/exhaust housing.
Got the lower unit disassembled in about 15min no problemmo after that.
New prop shaft is already on the way.
If this were an airplane or some other mission-critical application, I'd be doing a complete teardown to make sure the crank isn't bent. There must have been an AWFUL lot of force transmitted into those gears to twist the shaft like that.
But the gearbox looks pristine so..
