Kyosho 94108 Blue Waterproof Flexible Boots - 2 Pack  [KY-94108]

Flexible waterproof covers for hull drivetrains

This Kyosho 94108 pair of waterproof flexible boots is an RC-scale replacement part supplied in blue, sold as 2 pcs. It serves as a compact protective cover for exposed drivetrain and linkage points on model boats, keeping water and debris away from moving joints while allowing required articulation.

Intended for use with Kyosho Boats & Yachts Jet Stream 600 category models, the boots are simple wear items that help prevent water ingress and abrasive damage during normal operation. Their elastic profile lets components move freely while providing a barrier that protects nearby shafts and couplings.

Fitting is a basic workshop task: slide the boot over the exposed coupling or joint, making sure it seats without stretching across the pivot. Confirm unhindered movement after fitting and check the rubber regularly for splits or hardening. After saltwater exposure, flush and dry parts to reduce corrosion risk.

Store a spare set as routine maintenance stock and swap them out when flexibility or sealing performance declines.
