Both Minnkota and Motor Guide produce electric trolling motors big
enough to use as auxiliaries on small sailboats. Has anyone tried

Does anyone know the motor configuration (permanent magnet, shunt wound,
series wound)?

BS

You will not be able to use them an generators. The incoming power
goes through built in electronic controls for speed and there is no
way that power from the windings would find its way back through that
controller without drastic modification.
