The Honda 90703-PNA-300 Dowel Pin (4.2X10.3) is a genuine OEM component designed for BF115, BF135, BF140, and BF150 outboard motors. As a direct Honda OEM part, it is manufactured to the exact dimensions required to maintain precise alignment between mating components. Verify your motor's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this listing covers specific production ranges.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this dowel pin meets the exact dimensional tolerances your outboard was built around, ensuring correct positional alignment between paired surfaces.
- Exact-Dimension Fit — the 4.2 x 10.3 mm specification is a precise call-out; using an incorrect size risks misalignment of critical mating components, so confirm this matches your motor's parts diagram.
- Broad BF-Series Coverage — listed for BF115, BF135, BF140, and BF150 outboard motors; check your serial number against the fitment table to confirm the correct part for your specific unit.
A dowel pin is a small cylindrical locating fastener used to align two mating parts — such as housings, flanges, or covers — so they seat in exactly the right position relative to each other. Without it, components can shift slightly during assembly, causing uneven gasket loading, misaligned bores, or improper sealing. When a dowel pin is lost, damaged, or omitted during a rebuild, the reassembled joint may look correct but will be off-position, leading to leaks or accelerated wear on the mating surfaces.
