What You'll Learn
The fuel filter is located under the cowling on the left-hand side
The fuel filter on the 2005 Yamaha HPDI 250 is located under the cowling on the left-hand side. This is the small plastic filter housing that can be accessed by removing the cowling and looking from the prop. The filter is inside a clear plastic bowl, which can be tricky to remove due to swelling caused by ethanol in the fuel.
To replace the fuel filter, first remove the cowling to access the filter housing. Disconnect the wire for the water-in-fuel alarm from the blue connector using a screwdriver. Place a rag under the bowl to catch any fuel that may leak out. Use channel locks to try and remove the clear bowl; it may spin off, but if not, gently pry it free with a screwdriver.
Once the bowl is removed, you can access and replace the fuel filter. This filter should be changed regularly, especially with the use of E-10 fuel, which can cause the plastic bowl to swell and make removal more challenging.
It is recommended to check and replace the filter every 200-250 hours or 3-4 years as preventative maintenance on a well-maintained engine. This interval may vary depending on the size of the engine and fuel tank and the frequency of use.

The fuel filter is inside a clear plastic bowl
The fuel filter on a 2005 Yamaha HPDI 250 is located inside a clear plastic bowl. This bowl is situated under the cowling on the left-hand side, when looking from the prop. The bowl can be removed with channel locks, but it may require some force as the ethanol in the fuel can cause the bowl to swell, making it difficult to remove.
One method to counteract the swelling is to place the bowl in a freezer for a few minutes, allowing the plastic to shrink, before quickly remounting it. It is recommended to put a rag under the bowl when removing it, as some fuel will leak out.
The fuel filter should be changed every 200-250 hours or 3-4 years as preventative maintenance. This process can be tricky due to the swelling issue, and some people opt to replace the entire filter assembly, although this can be costly.
The filter is one of three that the owner can change. The first step is to remove the wire connected to the water-in-fuel alarm, disconnecting it from the blue connector. This can be done gently with a screwdriver.
It is worth noting that the fuel filter located inside the clear plastic bowl is different from the spin-on boat-mounted fuel/water separator, which is also present on some Yamaha HPDI engines.
