Tanaka USA website. They have the parts. Find the parts breakdown here before you start so you can refer to the exploded views.

Hopefully just the shear pin on the prop shaft, but could be a broken drive shaft. Those are good motors, I've been running a 3HP Tanaka for 25+ years.

Keep the motor turned off. Put it in gear and see if the prop spins easy in gear.. Its pretty easy to take the prop off and check it. Ive sheared a couple pins in my day

One other thing to check is the centrifugal clutch under the power head. Just remove 3 phillips head screws and drop that down to check, you will also need to loosen exhaust pipe connector clamp(2 screws), so you can drop the lower drive unit. You probably just sheared a pin.
