The Honda 91252-935-004 Water Seal (15mm) is a genuine OEM component designed for Honda portable and outboard motors, including the B75, BF100, BF15, BF75, BF8, and BF9. As a factory-original part, this seal is manufactured to Honda's exact specifications, ensuring a correct fit without guesswork or modification. Confirm your outboard's serial number against the fitment table before ordering, as Honda supersedes seals at serial breaks and listing coverage may vary by production run.
Key Features
- Genuine OEM Sealing Performance — manufactured to Honda's original specification, delivering the dimensional accuracy a water seal depends on to maintain a leak-free barrier in your outboard's water system
- Direct OEM Replacement — this is the correct Honda part number 91252-935-004, designed to drop into place exactly as the original, with no rework required
- Broad Outboard Coverage — listed for the B75, BF100, BF15, BF75, BF8, and BF9, including both portable and full-size Honda outboard motors
- Check Your Serial Number — Honda updates seal fitment at specific serial breaks, so verify your outboard's serial number against the compatibility table to confirm this is the right version for your motor
- Leak Prevention — a worn or degraded water seal allows water ingress into areas it should not reach, potentially compromising lubrication or cooling performance; replacing it promptly protects the integrity of the outboard's internal systems
A water seal in an outboard motor creates a pressurized barrier that prevents water from migrating along a rotating or reciprocating shaft into the motor's internal components. In a marine environment, maintaining that barrier is critical — seawater or fresh water that bypasses a failed seal can contaminate lubricants, accelerate internal wear, and lead to costly damage over time. Replacing a degraded water seal at the first sign of weeping or leakage is one of the most straightforward ways to protect the long-term health of your Honda outboard.
