'98 Nitro Motorguide Tracker Trolling Motor Woes

[nuke]

I have a MotorGuide Tracker Pro Series 60 trolling motor on my '98 Nitro and one side of the casting that holds the motor shaft to the support has cracked.  Since I'm probably upgrading the boat in about a year, I'm not spending $500-$1000 on a new trolling motor.  Does anyone have a used or dead same model trolling motor in their back pocket?  I could probably get an old Gator mount but I really don't want to have to drill new mounting holes.

I posted the above in the trolling motor section, but re-posted it here since other Nitro owners may be better suited to offer some assistance.
