Honda 40101-881-A04ZB Oil Case (Oyster Silver Metallic-U)

The Honda 40101-881-A04ZB Oil Case (Oyster Silver Metallic-U) is a genuine OEM replacement designed for BF8 portable outboard motors. As a direct Honda OEM component, this part is manufactured to the exact specifications of the original, ensuring it integrates correctly with your outboard's lower unit. This color-matched case — finished in Oyster Silver Metallic-U — is the correct variant for BF8 units produced in that color, so confirm your motor's color code before ordering.

Key Features

• Genuine Honda OEM Construction — sourced directly from Honda, this oil case meets the original design specifications for the BF8 portable outboard motor, with no compromise in fit or form.
• Color-Matched Variant — finished in Oyster Silver Metallic-U, this case is a specific color variant; verify your outboard's color code to confirm this is the correct unit for your motor.
• Serial Number Verification Advised — Honda supersedes parts at production serial breaks, so cross-check your BF8 serial number against the fitment table to confirm this is the right case for your motor.
• Structural Integrity for the Lower Unit — a correctly fitted oil case keeps the lower unit's gear oil sealed and protected, preventing contamination and maintaining proper lubrication of the gearcase components.

The oil case is a structural housing in the outboard's lower unit that encloses the gearcase and retains the gear oil that lubricates the drive gears, pinion, and propeller shaft. It forms a sealed cavity that keeps gear oil in and water out — essential in a marine environment where the lower unit runs submerged. A cracked, damaged, or improperly sealed oil case allows water ingress and gear oil loss, which leads to rapid wear or failure of the gearcase internals and can leave the motor unable to transmit power to the propeller.
