Kyosho 94108 Flexible Waterproof Boots for RC Boats 2 pcs  [KY-94108]

Protective boots for prop shafts and linkages

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.

Made to suit Kyosho Boats & Yachts Jet Stream 600 category models, these boots are intended as consumable protective items that reduce water ingress and wear on nearby components. Their flexible construction preserves motion range without binding while helping to protect shafts and couplings.

Fitment is simple: pull the boot over the exposed joint so it sits without tension across the movement point. After fitting, cycle the joint to confirm no binding. For saltwater operation, rinse and dry to minimise corrosive buildup on metallic parts.

Keep an extra set in your spares to avoid downtime, and replace boots at the first sign of cracking or loss of flexibility.
