    Default 15 hp 2 stroke carburetor pump diaphragm

    I purchased a Quicksilver repair kit, 1395-823707-2.
    This has the gaskets and diaphragm for the water pump.

    The question is, where does this neoprine gasket go?

    The documentation does not show this gasket.

    that kit fits several different carbs and hp motors. So.you may not need that diaphragm.

    Its for the older models that dont have the metal reed valves in them.(The diaphragm has reed valves as part of, first pic here)
    Second pic is the later type.

    Yes the later carbs have a plastic spacer with check valves built into it.
