The Honda 90402-V15-003 Seal Washer is a genuine OEM component designed for Honda portable and full-size outboard motors, including BF15, BF20, BF25, BF30, BF35, BF40, BF45, BF50, BF60, BF350, BFP8, BFP9, BFP15, BFP20, BFP60, and BF9 models. Sourced directly from Honda, this seal washer meets the same specifications as the part installed at the factory. Because Honda supersedes parts across serial number ranges, confirm your outboard's serial number against the fitment table before ordering to ensure this is the correct version for your motor.
Key Features
- Genuine Honda OEM — supplied directly from Honda, matching the original part your outboard shipped with for a dependable, like-for-like replacement.
- Sealing Integrity — designed to maintain a fluid-tight seal in marine service, preventing leaks that can compromise outboard performance or lead to fluid loss over time.
- Broad Outboard Coverage — listed for a wide range of Honda portable and full-size outboards, including BF and BFP series models from BF9 through BF350; verify your serial number against the fitment table to confirm fitment for your specific motor.
- Correct Part for the Job — using the OEM seal washer eliminates the guesswork of aftermarket substitutions where sealing dimensions must be exact to work properly in a marine environment.
A seal washer is a sealing fastener component that combines the clamping function of a standard washer with a soft or formed sealing face that prevents fluid from weeping past a threaded connection or drain point. In an outboard motor, these washers are used at oil drain plugs, banjo fittings, and other fluid passages where a metal-to-metal joint alone cannot hold a reliable seal. When a seal washer becomes compressed, cracked, or distorted through repeated use or overtightening, it loses its ability to seat properly and allows oil or water to escape — a small leak that can quickly become a bigger service issue if left unaddressed.
