Suzuki DF25–DF140 Fuel Filter (Older Models) – OEM 15410-87J10

This genuine Suzuki fuel filter (part number 15410-87J10) is specifically crafted for older Suzuki outboards in the 25 to 140 horsepower range. These engines, manufactured roughly between 1999 and 2007, rely on a clean fuel supply whether they use carburetion (like the DF25/30) or electronic fuel injection (like the DF40/50/60 and up). Over time, the stock filter can become clogged with impurities from the fuel tank, leading to reduced performance or hard starting. Replacing it with an OEM filter ensures your Suzuki’s fuel system is brought back to factory condition.

Installation is straightforward: the filter resides in-line in the engine’s fuel system under the cowl, often in a transparent plastic cup so you can see the fuel. By keeping up with filter changes (Suzuki recommends at least annually or every 100 hours), you protect your outboard from fuel starvation and potential engine damage. Notably, this filter also cross-fits some Johnson/Evinrude 4-stroke outboards (25–70HP) from the early 2000s, since those were built by Suzuki – meaning one part can support multiple brands.

• Recommended for owners of older Suzuki motors who want their boat’s engine to run smoothly – whether the motor is used for fishing, cruising, or as a kicker, clean fuel is the key to reliability
• Especially critical for pre-2007 models, where tank deposits can clog the fuel system – this filter prevents rough idling and makes cold starts easier in the morning
• Johnson/Evinrude compatible: If you have a Johnson or Evinrude 4-stroke 25–70HP from the early 2000s (Suzuki-built), this filter (Suzuki #15410-87J10) fits and will provide the same protection
• OEM vs aftermarket: Replacing with a genuine Suzuki filter ensures materials and dimensions exactly meet spec – you avoid risks from aftermarket filters (poor sealing, less filtration) and ensure maximum reliability
