    I second the "Yes."

    I've got a Racor S3213 with a clear bowl on the bottom of the filter.

    I believe it is not recommended by Mercury to add any secondary filters in the fuel system the engine is already equipped with a VST sysyem additional filters can cause fuel flow restriction which can cause performance issues.

    Please see the Forum Announcements, and provide the REQUIRED info when posting. Thanks!\

    DEPENDING on where your engine serial number falls, it MAY BE RECOMMENDED, or it MAY BE STRONGLY DISCOURAGED.

    This is the 4-stroke forum. Optis, depending on displacement, go in one of the 3 other Mercury forums above this one.
