The Honda 99101-KPB-1020 Main Jet (#102) is a genuine OEM component designed for BF15 and BF9 portable outboard motors. As a direct Honda OEM part, it carries the exact sizing and calibration required by the carburetor on these motors. This main jet is listed for both the BF15 and BF9 — confirm the jet size (#102) matches your specific unit before ordering, as carburetor jet specifications can vary across serial ranges. Always verify part number 99101-KPB-1020 against your motor's parts diagram to ensure this is the correct selection.
Key Features
- Exact Fuel Metering — a genuine OEM main jet delivers the precise orifice diameter the carburetor depends on for correct air-fuel ratio at wide-open throttle; an incorrect jet size causes rich or lean running across the entire power range
- OEM Sizing (#102) — the #102 designation identifies the orifice calibration; match this number to the jet size called out in your motor's parts diagram before installing
- Fits BF15 and BF9 Portable Outboard Motors — listed for Honda BF15 and BF9 outboards; Honda supersedes carburetor jets at serial breaks, so check your motor's serial number against the fitment table to confirm applicability
- Drop-In Replacement — this jet installs directly into the carburetor's main jet port with no modification, restoring fuel delivery to the original Honda specification
The main jet is a precisely sized orifice inside the carburetor that meters the volume of fuel drawn into the engine at mid to wide-open throttle. Its calibrated size governs how much fuel mixes with incoming air, directly affecting power output, fuel efficiency, and clean combustion. When a main jet becomes clogged, corroded, or worn, the motor will run lean — losing power, running rough, or refusing to reach full throttle — or rich, resulting in excessive fuel consumption and fouled plugs. Replacing a faulty jet with the correct genuine OEM part restores proper fuel delivery and brings the outboard back to its designed operating characteristics.
