Ciuouient Lower Unit Rebuild Kit for Minn Kota 4" — 22-Piece Brush & Seal Set, Brushes and Bearings

The Ciuouient 4" Brush & Seal Lower Unit Rebuild Kit is a 22-piece replacement set designed to restore electrical contact and watertight sealing in compatible Minn Kota trolling motors.

If your Minn Kota Ulterra, Ultrex, Terrova, Fortrex, Maxxum, PowerDrive, Traxxis, Riptide or compatible electric outboard is showing signs of wear in the lower unit—such as reduced power delivery, sparking, or water intrusion—this rebuild kit supplies the routine service parts needed to bring the lower unit back to reliable operation. The kit groups brushes, springs, seals, bearings and small hardware into one convenient package to simplify maintenance and reduce downtime on the water.

How will this kit improve motor performance?

Replacing worn brushes and seals restores consistent electrical contact and prevents water from reaching sensitive internal components. That helps the motor run more efficiently and reduces the risk of corrosion-related faults. Regular rebuilds also extend component life by preventing abrasive damage from degraded parts.

• Includes two carbon brushes and springs for steady armature contact
• New seal kit pieces to re-establish lower-unit watertightness
• Armature bearing and thrust spacers to maintain correct shaft alignment

Which models does this 22-piece kit fit?

This kit is engineered to match common lower-unit parts used across many Minn Kota models with similar 74–101 lb thrust and 1/2HP electric outboard configurations. Confirm your motor’s part numbers before installing to ensure a correct fit. The listing includes OEM-style part numbers to make cross-referencing straightforward.

• Compatible with Minn Kota Ulterra and Ultrex 80 lb thrust models
• Fits Terrova, Fortrex, Maxxum, PowerDrive, Traxxis, Riptide models in the 74–101 lb range
• Also compatible with Minn Kota 1/2HP electric outboard models

What specific parts are included in the set?

The kit bundles the small but critical parts you typically replace during a lower-unit service. All included items are listed with corresponding part numbers so you can verify compatibility or purchase individual OEM replacements if needed. The hardware covers both electrical and mechanical wear points.

• Seal kit set, two brushes, two brush springs, and two brush bolts
• Brush plate spacers, Belleville washers, armature bearing, thrust spacers
• Steel washer, tube, and E-clip — full 22-piece complement

How difficult is installation and what should I check first?

Installation requires basic mechanical skills, common hand tools, and careful attention to part orientation and torque. Before starting, confirm the kit part numbers against your motor’s service manual and inspect the lower unit for additional damage that may need professional repair. If you’re unsure, consult a technician to avoid accidental damage.

• Confirm part numbers (#2889460, #188-094, #975-041 and others) before purchase
• Follow torque and order-of-assembly guidance from your motor’s service documentation
• Inspect armature, commutator, and lower housing for wear before reassembly

Who this kit is for: This Ciuouient 4" Brush & Seal Lower Unit Rebuild Kit is aimed at boat owners, anglers and marine technicians who perform routine maintenance on Minn Kota-style trolling motors and small electric outboards. It’s ideal for DIYers comfortable with disassembling lower units, shops that service multiple motor models, and anyone who prefers stocking a full repair set to minimize time off the water. Always verify compatibility with your motor’s part numbers and seek professional help for complex or corroded failures.
