If the driveshaft is stuck in the crankshaft, he’s going to have to use wedges to break the gearcase free of the exhaust housing. This will probably break the impeller housing, the impeller key will get yanked up through the impeller housing.

The gearcase will come off, but then the driveshaft is still stuck on the motor.

With smaller motors, I’ve had about a 50% success rate on removing the driveshafts by hanging motors upside down in a vice by the driveshaft, taking a piece of flat stock iron and placing it across the bottom of the exhausting housing, and using an 8lb sledge to pound on the bottom of the exhaust housing.

Not sure if you can do this on a big motor.

With small motors (<10hp), the exhaust housing can be easily damaged doing this. It requires a full teardown by yanking the powerhead clear of the motor, then trying the same process on the bottom of the powerhead (more forgiving than the exhaust housing, and generally larger surface area to strike and place the flat stock over.

I think you may be looking for a new motor, unless you have a parts motor you can swap crank shafts with, and deep pockets to pay for a lot of labor for a mechanic who’s even willing to take that kind of a job on (winter time might motivate the right mechanic to do that job….if you have the parts to replace!).
