The Honda 91302-PNA-003 O-Ring (7.45X3.61) is a genuine OEM sealing ring designed for Honda outboard motors, including the BF75, BF90, BF100, BF115, BF135, BF140, BF150, BF175, BF200, BF225, and BF250. As a direct Honda OEM component, this O-Ring (7.45X3.61) is manufactured to the exact dimensions required for a proper seal in your outboard's fluid or pressure circuits. Confirm fitment against your outboard's serial number using the compatibility table before ordering, as Honda supersedes parts at specific serial breaks across these models.
Key Features
- Genuine Honda OEM Sealing — manufactured to the precise 7.45 x 3.61 mm dimensions Honda specifies, ensuring the correct compression and seal integrity this application requires
- Exact-Dimension Replacement — sized to drop directly into the original groove without modification; an incorrectly sized o-ring will not seat properly and will allow fluid or pressure loss
- Broad Outboard Coverage — listed for Honda outboard motors including the BF75, BF90, BF100, BF115, BF135, BF140, BF150, BF175, BF200, BF225, and BF250
- Serial Number Verification Recommended — Honda updates sealing components at production serial breaks; check your outboard's serial number against the fitment table to confirm part number 91302-PNA-003 is correct for your unit
An O-ring is a circular sealing element that sits in a machined groove between two mating surfaces or around a shaft or port, preventing fluid or pressure from escaping the joint. In a marine outboard like the Honda BF-series, o-rings appear throughout the cooling, lubrication, and fuel systems to maintain tight, leak-free connections in a demanding saltwater environment. When an o-ring hardens, cracks, or is compressed beyond its service life, the seal fails and fluid loss or pressure drop follows — making timely replacement with the correct-dimension part essential to keeping the outboard running properly.
