The thing is, we can go through lots of what you'd like to be constructive advice, but what it boils down to is this:-
You need that motor to work, every time. If it doesn't, you may be in deep deep trouble.
Your 1st post basically asks for advice for a novice on doing a job best left to the experts, on repairing a long neglected, partially siezed piece of equipment that could have any number of other faults from being left standing.Plus you will be relying on it to get you home.
It's worth paying an outboard shop to spend an hour on it to see if it's worth doing. They'll tell you if it's scrap or not and should be able to tell you what work actually does need doing to it.
Realistically, I'd expect the motor to need a full strip and inspection to work out what's stiff,an internal clean, new gasket set , plus a new impeller, plugs and gear oil. That's nearing the cost of a running motor-before you even add in the cost of replacing broken bolts etc and some labour.
