    21 Micron filter by Emmett - Pearland, TexasApril 26, 2013
    This is labeled as a replacement for the Mercury 35-802893Q, but when received the specs reflect it is a 21 Micron filter! NOT the 10 Micron filer I need. I had looked for the specs on-line before ordering and they were not listed. The 10 Micron P/N is 18-7945 according to the West Marine website.

    Affordable and quick. by Daniel - Hills, IowaJuly 06, 2012
    I haven't had a chance to run it in the water yet but it works on the muffs. Not too much to say, it fits right and was shipped quick. Shipped out of Ankeny, IA and I live in Hills, IA so I had my parts the next morning.

    Great product! by Michael - Noblesville, IndianaOctober 07, 2013
    I like the fact that the hose barbs came with the kit and that the filter was shrink wrapped to protect it. Installation was a breeze. One note for other installers: pre-fill the filter with gas before you screw it onto the housing it will make start up much easier.

    Great Product by Stephen - Hubert, North CarolinaJuly 04, 2013
    If you do not already have one of these installed on your boat, you should waste no time getting one soon! The one I received did not have the two plugs for the unused ports. Luckily I already had some so installing it wasn't a problem.
