If its just stuck rings, you are laughing.

You will get a wide variety of responses on what to use from vinegar to Deep Creepto ATF/Acetone mixture to "insert concoction here"

If you get the rewind off, try to rotate the flywheel back and forth and see if you get just the slightest movement. If so, it’s likely to be just stuck rings. You should be able to free those up fairly easily with some Penetrating Witch’s Brew of your choice. 😉

I would be sure that the sticking is not just in the lower unit so I would remove the lower unit. Have to anyway to put in the pump impeller. Good luck with this project!

The most important tool for this job is Patience ❗ ❗
What ever you put in the cylinders to soak
let it set and soak a few days before you try it.
And most important, Don’t force it.
Good luck.

my really bad stuck 9.5 took a good 3 weeks to free up but proceed as per your gut feel,
1- took out the cyl head …
2- both cyl were half way…so I spread in some penetrating oil
3- waited few days and tried to rotate the flywheel ….. nothing moved 🙁
4- added more juice and repeated flywheel moves back and forth every few days for weeks
5- after a few weeks got the big fellow out and used a 1.5 inch x 12 inch round peg to alternately & gently smack the pistons..and added juice
6- after a few days the "marked" flywheel moved a few degrees 😀
7-continue with the big guy and alternately wacked the pistons each time seeing a few degrees rotation on the fw and adding juice
8- one day….happiness …total movement 😀 😀
9- reinstalled the cyl head…. compression was low 70’s

runs great next to my 75 ETEC

I remember our neighbor at the beach, he had one, not sure if it was a 53 or 54 though, it had electric starting too. The man was very particular about his stuff, so the rig was in immaculate condition, even considering it was used in salt water. I remember watching him commission the rig ever year, but can honestly say I don’t remember seeing him use it! He would manually crank the engine to avoid wear on the starter motor. Bill Marvin was his name, I’m sure he has passed by now, but I hope someone preserved that boat…

Sorry to hear it is stuck, but I’m betting you can free her up without too much more than a new head gasket, some penetrating oil, and the previously described patience! Be sure to pay attention to the great advice about the gearcase being stuck though, drain the gear lube to evaluate…You will want to pull that gearcase off anyway, to replace the impeller and clean/lube the driveshaft splines.
