Don't discount anything until you actually open it up. If the water was cold and did not have much dissolved oxygen, there might not be as much damage as you would imagine. HOWEVER: now that it is out of the water and in the air, time is of the essence. It is imperative that you disassemble it immediately and dry all internal parts.

unless damaged, coils and CD boxes are sealed and should have survived.---unless the engine was a hundred feet under.

Flush with fresh water and dry using a hair dryer, forced air dryer or such. I have pulled engines out of fresh water that had minimum damage from being under a while.

I would spray it with 2 cycle oil after drying and rotate it by hand to try and get lube inside.

Don't do this if any mud or debris has entered the intake. If that happens, you will need to tear it down before rotating or you will do additional damage.

The thing to worry about most are the bearings. I had one that sunk and was recovered and ran good for about five hours and then came apart. Upon investigating, we found the bearings had pitting on them.
