Do any 24VDC high torque servos exist?

[DD]

The robotic watercraft we are building runs on a 24VDC electrical system.
The servo needs to control steering and needs high torque (>100 lb-in)
especially in choppy waters. I am having trouble finding a high torque, low
voltage servo. Should we just run a 75VDC servo at a lower voltage, or
perform the voltage conversion? Is there a servo that meets our
requirements? We would like to keep the wiring simple. I am puzzled why it
is so hard to find.

Thanks ~ DD

have better luck?
