You sound like you know your way around motors.

Dont know your motor but most outboards have

kill switch and key that let motor run when in the open position( open=run,closed=no run)

If you dont have a manual get one.They are worth every penny.Try the library,the tab at the top of the page,amazon.com,NAPA,ebay,etc.

From your post it seems with the help of a manual it would be cake to solve your problem.

Good luck.
