Stuck in Reverse

We tried leaving the slip but forgot a line so I tried to take it out of reverse, it was stuck in reverse, so turned the engine off and recapture all the dock lines.  The cotter pin for the gear shift clevis pin broke, and both fell down the binnacle.  We found some and replaced.  Thought it would be easy but a bolt that holds the compass was corroded, required the use of the impact driver(love this tool).  Then the compass fell cracking the case now after some super glue, a bunch of corrosion x, we are mobile again.  Now we've got to go pump out.
