The Honda 94540-03029 E-Ring (3mm) is a genuine OEM retaining ring designed for Honda BF-series and BFP-series outboard motors, including models BF100, BF115, BF130, BF135, BF15, BF150. As a genuine Honda OEM component, this E-ring is manufactured to the same specification as the original, ensuring an exact match for the groove and shaft dimensions it is meant to retain. Verify your outboard's serial number against the fitment table to confirm this 3mm ring is the correct variant for your specific motor build.
Key Features
- Genuine OEM Retaining Ring — sourced directly from Honda, this E-ring matches the original groove profile and diameter for positive, secure retention on the shaft it clips to
- 3mm Variant — the (3mm) designation identifies the shaft diameter this ring is sized for; confirm this matches your motor's specification before ordering
- Broad BF-Series Coverage — listed for Honda portable and full-size outboard motors from the BF8 through the BF250, including BFP portable models; check your serial number against the fitment table to verify applicability
- Keeps Components Seated — a worn, sprung, or missing E-ring allows retained components to shift or separate; replacing this ring restores proper positional control of the parts it secures
An E-ring is a small external retaining ring that snaps into a machined groove on a shaft or pin to prevent axial movement of the components it holds in place. In Honda outboard motors, retaining rings like this one are used throughout the engine, gearcase, and control linkages wherever a component must be secured against a shaft without the use of a threaded fastener. When an E-ring becomes deformed, corroded, or loses its spring tension, the part it retains can shift out of position or disengage entirely, leading to operational issues that can be difficult to trace. Replacing a failed ring with the correct genuine Honda part, part number 94540-03029, restores the original retention force and keeps the assembly functioning as designed.
