T-H Marine CB1 Splashwell Cable Boot – 3", Black Vinyl, UV & Fuel Resistant
The T-H Marine CB1 is a 3" splashwell cable boot designed to seal the splashwell opening around wiring and cables on outboard-powered boats. The open-center design provides a fully open pass-through area during rigging, allowing cables and wiring to be routed through the splashwell without threading through a tight seal. Once rigging is complete, the boot seals around the cables to protect against water intrusion through the splashwell opening.
Constructed from rugged black vinyl that resists UV rays, gasoline, and oil — materials the splashwell boot is regularly exposed to in an outboard installation.

Parts Desk Insights
Best Use Case: The CB1 is the correct boot when you need to seal a 3" splashwell opening around cables and wiring on an outboard boat — most commonly during a re-rig or when replacing a cracked or deteriorated original boot. The open-center design is a practical advantage during rigging: cables can be routed through the open boot without needing to thread them through a tight seal, and the boot then closes around the cables once rigging is complete. The black vinyl construction resists UV fading and is compatible with gasoline and oil exposure, which is important for a component that lives in the splashwell environment. Confirm your splashwell opening is 3" before ordering.
