    by Emmett from Pearland, Texas on April 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.

    by Billy from Gadsden, Alabama on September 07, 2015
    Catalog said it was a replacement for the Volvo Penta filter. GSI series engine specs call for a 10 micron. This filter is rated 21 micron. I'll update to correct size shortly.

    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.

    Q:
    Does this replace a mallory 9-37815 or OEM 981911?
    A:
    No this is the correct one: http://www.iboats.com/Replacement-Canister-Filter-18-7861-Sierra/dm/view_id.173336
    Q:
    Does it come with the gasket and O-ring?
    A:
    Yes. The O-ring is attached to the filter and it acts as a seal. There is no gasket necessary.
    Q:
    Do you carry the gasket and o ring for this filter?
    Q:
    I am replacing a OMC filter #174144, the center hole is 1 inch the canister is 4 inches in dia will this unit fit?
    A:
    Sierra cannot give dimensions, they can only match up by application. This is not the correct filter for that OEM number. The correct replacement is part 18-7846.
    Q:
    Will this filter replace Volvo 3862228 ?
    A:
    No you will need 18-7989.
    Q:
    My fule lines are 3/8 id, will this filter work for me ?
    A:
    Sierra cannot match it up by measurements. They can only match it up by engine application. Contact us at the number at the top of the page for more assistance.
    Q:
    I have an older boat, it has a water fuel separator filter (probably original). On the front of the filter, clearly states Sierra 18-7848, on the back, states "replaces OMC (174144). Is this the right filter? On the front, there is only 18-7848, there is no -1 at the end. Thanks?
    A:
    The "-1" indicates packaging only. It is the same part.
    Q:
    Can youbuy just the filter or does it only come in a kit?
    A:
    Filter is 18-7844.
