Trolling motor advice needed

[Lively1]

So I was out this morning having a grand old time and my trolling motor quit working. That is, the prop doesn't turn but the directional motor to turn it this way and that does work. (It's an older bow mount with foot pedal deal.)  Looking it over, cleaned the connector plug which had some corrosion hoping it would solve the issue, but it didn't.   Then I noticed, wait a minute.. the shaft is cracked.  And bent a little. Must be from when it caught on a dock post backing out a month ago.. Maybe thats where all the water is coming from that drains out the head of the unit after its stowed and I am cruising to the next fishing spot..

 

So.. I'm guessing I need a replacement shaft.. but what else?  Is the motor possibly damaged by water in the shaft? Or water running out the top of the shaft into the head?  How do I figure out what to fix and what to replace?  Or maybe its time to just upgrade to a nice new one with iPilot? (after I win the lottery)..
