To get the drive washer off, strip the motor down to the crankcase, place it on it's back, and tap the crank with a soft-faced hammer. If you need to give it a good whack, slip a nut on the threads and use a brass drift.
DO NOT PRY IT OFF. That "Washer" is actually a one-way clutch, and any dents in the back will affect its function.
to reassemble, make sure the washer engages the two flats inside the clutch, insert the crank in the back, then torque on a old propeller (Use some flatwashers, new 10-24 nuts and the proper wrenches!) to seat the crank.
