Fuel Filter for Honda BF115–BF225 (115–225 HP, Water Separating) – Replaces 16901-ZY3-003

This fuel filter for Honda BF115–BF225 is engineered to meet the demands of Honda’s medium to large outboard engines. As horsepower increases (up to 225 HP), the engines require greater fuel flow and a higher level of protection. The 16901-ZY3-003 filter combines standard particle filtration with a water-separating function – critical for modern fuels which often contain ethanol and can absorb moisture from the air.

Key features and benefits:

• Wide compatibility with Honda engines: Whether you have an older Honda BF115/BF130 or a newer BF150/BF225, this filter will fit perfectly. Honda 4-stroke motors in the 115–225 HP range are used both for recreation (fishing, watersports) and commercial purposes. What they have in common is the need for clean fuel – and this filter is the one-stop solution for that entire lineup.
• Water-separating design: The filter is constructed not only to stop solid particles (rust, sediment) but also to trap water. The internal media or coating repels water droplets, which then collect at the bottom of the filter (or in a dedicated bowl, if one is present). By doing so, it protects critical components like the fuel pump and injectors from exposure to water, which can cause corrosion or uneven combustion. Keeping water out of the fuel system is especially important with ethanol-blended fuels that attract moisture.
• Improved fuel efficiency: When fuel is free of contaminants and water, the engine burns the mixture more efficiently. This means smoother operation, full power when you need it, and even better fuel economy. For large motors like the 200–225 HP, the difference can be felt in more consistent torque during acceleration and less tendency to “bog down” under changing loads. A clean filter ensures the engine isn’t starved or disrupted by fuel impurities.
• OEM quality and easy installation: This filter is built to Honda’s standards, ensuring it fits exactly into the holder/housing of the original filter. Replacement requires no additional adapters – simply shut off the engine, close the fuel valve if applicable, remove the old filter and install the new one, making sure the gasket is properly seated. Then prime the system if necessary and start the engine to check for leaks. The whole process is quick and straightforward, making it easy to include in your routine maintenance.
• Prevention of costly repairs: Water in fuel can lead to engine “sputtering” or stalling – since water doesn’t burn, it effectively starves the engine momentarily. It also causes rust on precision injector parts. Debris, on the other hand, can clog fuel injectors or carburetor jets (in older models). By regularly replacing this filter, you minimize the risk of such damage. The cost of the filter is negligible compared to a potential injector rebuild or engine repair. In essence, it’s cheap insurance for your motor.

For best results, replace the Honda 16901-ZY3-003 fuel filter at least once a year (for example, at the start of each boating season) or more frequently under heavy use. If your boat operates in high-humidity environments or if you refuel from varied sources, always keep a spare filter on board. This will allow you to react quickly if you notice symptoms of fuel problems, getting you back to boating with minimal downtime.
