It would have been better to submerge it in clean water and let soak overnight. Then completely disassemble and spray everything with WD-40. Assemble with new seals/gaskets and test run.

The most important thing to do is get it running again as quick as you can.
Yes, the standard procedure when dunked in salt water is to re-submerge the motor in fresh water IMMEDIATELY. Do NOT let it sit out in the air.
The next thing to do is to get it running again as soon as possible after dissembling the carburetors, draining the water from then and reassembling. There is no need to disassemble anything else.
Get it running and let it run for a good long while, like a half hour or an hour.
