Re: 50 force drive shaft broke
They can be difficult to get out but before you go with esoteric remedies, try setting the engine vertical and tapping firmly on the crankshaft nut. Use an aluminum or brass block to actually hammer on so you don't **** up the threads. If it does come out, it will be a splined piece about 1 1/2 inches long--you won't miss it on the ground.
Since they almost always break cleanly, If the splined piece doesn't come out, try a long rod with some super glue on the end.
