Terrova, Ultrex and Ulterra QUEST share the same brushless motor: 90 lb of thrust at 24V, 115 lb at 36V, and a 60-amp max draw. They differ in how you steer and how the motor gets in and out of the water. Pick the Ultrex for direct foot steering, the Ulterra if you want it to stow itself, and the Terrova to save $500–$700.

Steering: cable vs. electric
The Ultrex's foot pedal is connected to the motor by steering cables, so turning the pedal turns the motor directly and instantly. You always know where the motor points by the angle of your foot. Tournament anglers working a bank at speed tend to prefer it.
The Terrova and Ulterra steer with an electric motor in the head. You can use the foot pedal, but these motors are built around the wireless remote, the app and GPS modes. Steering by pedal has a slight delay that some anglers never notice and others can't stand. If you mostly fish from Spot-Lock or the remote, electric steering is the better fit.
Stow and deploy
The Terrova and Ultrex fold down and up by hand, helped by a lift-assist mechanism. The Ulterra does it for you, from the remote, foot pedal, app or fish finder, and adds Power Trim to adjust motor depth on the fly. If you move spots 30 times a day or fish rough water, that convenience is the main reason to spend the extra.
Batteries: all three are the same
Because the motor is identical, battery needs are too. At 24V you need two 12V batteries in series or one 24V lithium. At 36V, three 12V batteries or one 36V lithium. Plan for the 60-amp draw: a 60-amp breaker, and lithium batteries whose BMS is rated for at least 70 amps continuous.
Our estimates with 100Ah lithium batteries: about 3.9 hours of continuous running at half speed, and around 9 hours at 30%. Wind and Spot-Lock in current push draw up, so many anglers fishing full days go to 36V lithium in the 100–120Ah range. See our Minn Kota battery guide for details.
Which should you buy?
Buy the Ultrex QUEST if
- You steer mostly with your foot
- You fish tournaments or run banks fast
- Your pedal sits close to the motor
Buy the Terrova QUEST if
- You mostly use the remote, app or Spot-Lock
- You need a 72" shaft
- You want the lowest QUEST price
Buy the Ulterra QUEST if hands-free stow and deploy is worth about $700 over the Terrova to you. It is for many anglers with bad backs, tall bows or rough water.

FAQ
Is the Ultrex more powerful than the Terrova?
No. In the QUEST versions both produce 90 lb at 24V and 115 lb at 36V, with the same 60-amp max draw.
Can the Ultrex use a wireless remote?
Yes. The Ultrex QUEST includes a micro remote, and it works with GPS modes, the app and connected Humminbird units.
What shaft length do I need?
Most bass boats use 45" to 60". Taller bows and rougher water call for longer shafts so the prop stays submerged. Measure from the mounting surface to the waterline and follow Minn Kota's shaft guide.
