That's pretty bad, dunno if I've seen worse save for in a junkyard where a head has been off for 10+ years and filled with water.

Too bad about the rods, but at least the crank got saved. That is a classic case of rust beneath the piston on the skirt. When the piston goes down, it just digs up that rust and makes it impossible to ge the pistons down to where you can get the clips out. If you get desperate to save the rods, you can sometimes go ahead and split the cases and take the crank out and carefully carve away at the pistons the get the pins out. Or sometimes drive the out going the other way (North you might say), that way you are not beating against the rod, only the already useless piston. But sometimes you cant even get the piston to go down far enough to get the barrel past the studs on the case. Sometimes you just have to do what you just did. Painful . . .

Back when I worked on Jet skis we had that problem all the time ! Guy sumerge the ski then it won't start so they park it then about a year later they want to fix it .

Just use to raise the cylinders up and drive it apart with a air hammer .
