Would this bottom end work?
Typically these bikes will go all the way over your ankles in water without an issue and almost to your knees. If your foot pegs were barely in the water it wasn't deep enough to get water in the engine through the intake or exhaust and the engine would barely even be touching the water. They will die easy in a water crossing if you don't lay on the gas due to extra resistance from the water pressure. As to the damage in your engine, I think that was done long ago. I have over 46,000 miles on mine now. I have ridden through water over my ankles on multiple occasions and at 42,000 miles my engine was spotless compared to that. Sorry to hear about the bad news. There is no telling what that engine has been through so it may be best to replace it to get you up and going and then tinker and rebuild at a later date.

If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

I have an 04 engine that I got in trade that supposedly ran when it was parted out. I haven’t even spun it yet as it’s a winter project I’ve been hoarding. I’ve been saving it for the time when I had a day like you had. It’s yours if you want it, but it’ll be more expensive than the 89 buck eBay bottom end.
SORRY FELLAS THIS IS NOT FOR SALE. Just trying to help this guy out.
I swamped an Acura TL in a Florida hurricane so I feel your pain.
If it was me, I’d try Purple’s advice and try to flush it first.
Get your location out here. Maybe others can help.
If you need mine, send me a PM.

You are seriously over thinking this. I bet the rings are stuck in the grooves right? Put a light hone pattern on the cylinder and new rings on that piston and put it back together. Trust me it will run just fine. Change the oil and filter after an hour. You definitely don't need another engine.
If you had the know how, should have drained crankcase direct after immersion. Don’t let it set. If need a dealer to change oil, should NOT be attempting a rebuild. Much more to it than an internet session will tutor to success. Get complete running motor and assembly, you should be able to swap success fully or pay a technician. Cranks don’t get changed, roller bearing crank. One rebuilds them. Bearings rust no good.
Have fun stay stock.
