A trolling motor is a motor plus a controller built in. I would never recommend running a 12V trolling motor at 24V unless the manufacturer specifically said it was OK. It might only last a few milliseconds before the electronics fried. The motor itself would still be OK, but the "trolling motor" purchased product would be dead.
Agreed; if we're talking about something than just a straight motor, a
different set of rules applies. Driving anything more than a simple
power sink - e.g., a diode or a motor - with PWM is not likely to lead
to good results.
