Suzuki Outboard Fuel Filter 15410-98500 (DF4–DF70 & DF150/175)
One part number, numerous applications – the Suzuki 15410-98500 fuel filter is used across a wide array of Suzuki outboard engines, acting as a common safeguard for their fuel systems. This inline filter is found on small 2-stroke portables (like DT4, DT5) and 4-stroke DF4/DF6 engines, mid-range 4-strokes (DF9.9, DF15, DF40, DF50, DF60, DF70 from early 2000s), and even the first-generation Suzuki EFI big block motors (DF150/175 circa 2007-2009) as a low-pressure filter before the high-pressure pump. Its primary job is to screen the fuel for any contaminants – be it dust, rust, or fuel tank debris – and to ensure only clean fuel reaches your engine’s carburetors or fuel injectors.
Suzuki’s engineering demands reliable filtration, and this filter meets those demands. It's built to exact Suzuki specifications, so it provides the correct fuel flow needed by each engine model while still trapping particles that could cause harm. By keeping impurities out, the filter helps avoid issues like lean running, power loss, or injector damage. It is a relatively small and inexpensive part, but extremely vital: failure to replace a clogged filter can lead to engine stalling or costly repairs.
Use Cases & Recommendations:
- Applicable to a variety of boats: from small inflatables with a 4hp kicker to larger fishing boats with a 175hp outboard – if your Suzuki uses this filter, keeping it fresh will keep your trips running smoothly.
- For older 2-stroke models (DT series) and early 4-strokes, this filter often handles fuel directly from portable tanks where contamination risk is higher; inspecting it regularly and replacing when dirty is crucial.
- On larger EFI engines like DF150/175, this filter protects the expensive high-pressure fuel pump and injectors by catching debris in the fuel – follow Suzuki’s guideline to replace it at scheduled intervals (often every 100 hours or annually).
- It's wise to carry a spare Suzuki 15410-98500 filter, particularly if you cruise in areas with limited service. A quick swap of a clogged filter can be the difference between a minor delay and a major tow back to shore.
