It has a quick release on it to remove it. You would need to figure on the wiring and cables connected to your boat with some type of connector to make it removable. It's easy to remove if it is the original. If it is too the ultrex, it has a little different mounting system so not sure if it is as easy to remove.
The Ultrex version takes loosening the three clamp bolts to remove it. The motor bracket stays attached to the motor.
