I have an older Yamaha 175 Saltwater Series 2 stroke on the back of my 21 Parker. I know everyone has always said with ethanol in our fuel we need to run a 10 micron fuel filter - which I have done using a Racor filter with the collection bulb in the bottom. I have yet to see any visible water in my buld - which is a good thing. However this filter runs about $30 give or take a few dollars. I have cross refferenced the number to a standard WIX filter which will fit my fuel filter block. This filter is only $11 but it is also 14 micron.
Here is my question. How improtant are those 4 microns ? I do all my own maitnenance work on my boat. I change filters frequently - I shoot for every 30 days but it probably works out to more to about every 45 days or so from May thru Oct. Not try to be shoot myself in the foot for a few dollars but every little bit helps if you save it wisely. Any thoughts ?
