Kyosho 94108 Waterproof Flexible Boots, Blue - Pair  [KY-94108]

Waterproof joint boots for scale boats

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.

Recommended for Kyosho Boats & Yachts Jet Stream 600 category models, the boots are simple consumable items that reduce the chance of water ingress and abrasive wear in routine use. Their flexible form permits necessary movement without binding and helps to protect nearby shafts and couplings from premature wear.

Installation is carried out in a basic workshop: seat the boot over the exposed shaft or coupling and confirm it does not place tension across the articulation. After fitting, check the joint for full travel and inspect periodically for cuts or loss of elasticity. Rinse and dry after saltwater use to avoid corrosive residue on metal parts.

Keep a spare pair for maintenance cycles and swap them as soon as sealing or flexibility degrades.
