Mercury FourStroke Fuel/Water Separator Question....
Good Afternoon All,
I have a Mercury 115hp FourStroke on an RT188. I was researching the maintenance for the motor and happened to see articles relating to fuel/water separators. Digging through the forum I find many references to OptiMax having an on-board separator; however, I am unable to locate information on the Four strokes models. Based on what I have read concerning ethanol fuels best practice would be to have a fuel/water separator installed. I would like to err on the side of caution and install one. I have a few questions and I am looking for advice.
I am considering a RACOR 320R-RAC-02 or RACOR 320R-RAC-02 with clear bowl. The vest install location appears to be inside the bilge compartment starboard side since the fuel line follows the same path.
- Does a Mercury 115hp FourStroke have a built-in fuel/water separator?
- If one is added I prefer RACOR 320R-RAC-02 with clear bowl however, since I am installing it in a compartment will that be a problem? The documentation states that it is for outboard use and part number RACOR 320R-RAC-01 with aluminum bowl is for outboard/inboard use. Are the terms inboard/outboard used to describe the motor location or the mounting location?
- Best I can tell the Mercury FourStroke consumes 10.6 GPH. Both filters are rated for 60GPH. Avoiding sharp turns or kinks, 60GPH would be adequate correct?
Thanks in advance.

Be sure to provide your serial number when you post on the Mercury 4-stroke Forum (required to properly identify WHICH engine you have, and what filtration it utilizes).
