Garmin Force Kraken is Garmin's high-thrust 36V flagship motor — targeting heavy bass boats and challenging conditions where maximum thrust matters. Here's how it compares to the Minn Kota Ultrex 112, the established premium competitor.

Garmin Force Kraken 57" (36V, 125 lb) $$$

Garmin's flagship high-thrust motor — 125 lb thrust at 36V, 6-inch diameter lower unit for efficiency, Force Remote, and GPS Anchor from Garmin's chartplotter network.

Minn Kota Ultrex 112 (60-inch, 36V) $$$

Minn Kota's top-thrust bow-mount — 112 lb thrust at 36V, Spot-Lock, Ultra-Quiet deployment, and One-Boat Network with Humminbird.

Who Needs a 36V 112+ lb Motor

Boats over 21 ft, heavy center consoles, boats with full livewells and heavy gear loads, and anglers who frequently fish in high-wind or current situations where an 80 lb 24V motor runs at full throttle just to hold position. For a 19-foot bass boat in moderate conditions, 80 lb at 24V is sufficient — 112+ lb at 36V is overkill. For a 22-foot tournament boat in wind on a large impoundment, 36V 112+ lb is the right choice.

Frequently Asked Questions

Is 125 lb thrust noticeably better than 112 lb?

13 lb additional thrust is measurable but not dramatically different in typical fishing conditions. At maximum thrust situations (heavy wind or strong current), 125 lb allows slightly more positioning authority. For most fishing scenarios, the difference between 112 lb and 125 lb is imperceptible.

Does Garmin Force Kraken work without a Garmin fish finder?

The motor operates (variable speed, forward/reverse) without a Garmin chartplotter. GPS Anchor requires a Garmin GPS-capable chartplotter on the NMEA 2000 network for optimal performance — the motor uses the chartplotter's GPS for position holding. Without a Garmin chartplotter, GPS anchor may have reduced performance or require the motor's internal GPS fallback.

Should I choose Force Kraken or Ultrex 112?

Same answer as the Force vs Ultrex comparison: choose based on your existing fish finder ecosystem. Garmin Force Kraken + Garmin ECHOMAP/GPSMAP = full integration. Ultrex 112 + Humminbird SOLIX/HELIX = One-Boat Network full integration. Either works on a mixed system via NMEA 2000 for basic GPS function.
