Troubleshooting & FAQ
How do I know if this fuel filter fits my specific Honda outboard?
The best way to confirm fitment is to check your engine's model and year against the compatibility table above. You can also verify by comparing your existing filter's part number to the numbers in our Part Number Matrix.
What’s the difference between this filter and the older 16900-SA5-003 part?
The 16900-SA5-004 is the official superseded part for the 16900-SA5-003. It is the current, genuine Honda replacement and is functionally identical and fully compatible with engines that originally used the older part number.
How often should I replace my outboard's fuel filter?
As a general rule, it's wise to replace your inline fuel filter annually or every 100 hours of operation, whichever comes first. Refer to your Honda owner's manual for the specific maintenance schedule for your engine.
What are the signs of a clogged or failing fuel filter?
Common symptoms include engine hesitation or bogging down at high speeds, difficulty starting, rough idling, or a noticeable loss of power. A visual inspection might also reveal sediment or water in the filter if it has a clear housing, though this model is opaque metal.
