Yamaha Outboard Fuel Filter 2-Pack — 65L-24563-00-00 Replacement
Water in your outboard fuel means a dead engine — sometimes miles from shore. The 65L-24563-00-00 fuel filter is the first line of defense for Yamaha F150, F200, F225, and SX250 outboards. This 2-pack gives you a spare on the boat and one in the shop, so you're never running without clean fuel.

Why This Filter Matters for Marine Engines
Marine fuel systems face challenges automotive engines never do — condensation from temperature swings, ethanol phase separation from sitting fuel, and constant vibration. A quality 10-micron fuel filter traps water droplets and debris before they reach your high-pressure injectors. At $29.99 for a 2-pack, replacing your filter every 100 hours or annually is cheap insurance against a $3,000+ injector job.
Key Specifications
-
Filtration Rating: 10 micron — catches debris but doesn't restrict flow at WOT
-
Water Separation: hydrophobic media repels water droplets
-
Ethanol-Resistant Media — won't break down with E10 fuel
-
Replaces OEM: 65L-24563-00-00, 65L24563, Sierra 18-7517
-
Pack Size: 2 filters — keep one onboard as a spare

When to Replace Your Outboard Fuel Filter
-
Every 100 engine hours or annually — whichever comes first
- After any episode of water-in-fuel alarm or rough running
- Before winter layup — don't let contaminated fuel sit in the system
- If you notice hesitation at WOT or hard starting
- After purchasing a used boat with unknown service history
Installation Tips
- Relieve fuel system pressure per your service manual
- Place a rag under the filter housing — expect some fuel spillage
- Remove old filter, clean the sealing surface
- Apply a thin film of clean engine oil to the new O-ring
- Hand-tighten + 3/4 turn (do not use a wrench — you'll crush the O-ring)
- Prime the fuel system and check for leaks before starting
FAQs
Will these fit my Yamaha F250?
Yes — the F250 uses the same fuel filter as the F225. The 65L-24563-00-00 is the correct replacement for the entire F150–F250 range (2004–2014).
Are these ethanol-safe?
Yes. The filter media is specifically formulated to resist ethanol-blended fuels (E10). It won't swell, degrade, or shed fibers in ethanol fuel — a common problem with budget aftermarket filters.
Can I use this on a Mercury outboard?
This filter cross-references to Mercury Verado 200–275 HP models (2005–2012). Verify your existing filter's dimensions and micron rating before swapping brands.
How do I know it's time to change the filter?
Symptoms of a clogged marine fuel filter: loss of RPM at wide-open throttle, surging at cruise speed, hard starting, and water-in-fuel alarms. If you're experiencing any of these, change the filter immediately.
