My friend had the same problem. He made a gizmo from a sparkplug. It had a zerk fitting in it. He pumped grease in and "voila" no more stuck piston.

DON'T MESS WITH THE CYLINDERS UNTIL YOU REMOVE THE LOWER UNIT AND THEN TRY TO TURN EACH INDIVIDUALLY. COULD BE IN THE LOWER UNIT.<br />SORRY FOR SHOUTING, TOO LAZY TO RE-TYPE more
Remove all of the engine's spark plugs with a socket wrench to alleviate the air pressure within the engine's cylinders. First, pull each spark plug's wire off the tip of the spark plug. Attach an appropriate-sized spark plug socket to a socket wrench; then remove each spark plug by turning the wrench in a counterclockwise direction.
Remove the accessory belts from the alternator, power steering pump, and any other belt-driven accessory. Each accessory attaches to the front of the engine with one or more brackets. The brackets are in turn attached to the engine with retaining bolts. Loosen the retaining bolts on each accessory bracket with a wrench; then slide the accessory toward the engine to reduce the tension on the accessory's belt. Slide the loose belt off the engine to remove it.
Remove the rocker arms and pushrods to remove the amount of force necessary to turn the engine. Each rocker arm is held in place with a single nut located in the center of the rocker arm. Remove the nut for each rocker arm with a wrench, then pull the rocker arms off the cylinder heads. Removing the rocker arms will free the pushrods, which can simply be pulled out of the cylinder head. [links]
Engines rarely seize, but when they do, it is almost always due to a long period of nonoperation. When an engine seizes, one or more pistons have literally become stuck against the cylinder's wall. Thankfully, just because an engine has seized does not necessarily mean that the entire engine must be rebuilt. The keys to freeing the engine are to reduce the air pressure within the engine's cylinders and to reduce the amount of force necessary to break the piston free by disconnecting the components that the engine turns, such as the alternator and power steering pump. more
How to free a seized jet ski engine?
Once you have located the correct cylinder you should insert the screwdriver or tool in as far as it will go. Then, attempting to line it up so that it goes in as deep as possible you will need to apply force to free the seized jet ski engine. [links]
In order to avoid this damage, if you suspect your jet ski engine may be seized, you should immediately stop cranking the engine and go to the testing outlined steps below.

Remove the valve covers from both cylinder heads by removing each valve cover's retaining bolts located on the lip of each valve cover with a wrench; then pull the valve covers off the cylinder heads to access the rocker arms. [links]
