    All the little black oil lines that go from each cylinder the the six way splitter to the return hose to the oil pump. I got the hose I need but broke a brass nipple was able to remove it safely. The center one behind the power bank with the solinoids. Can I get those at the hardware store or are they specific to mercury

    I would get the hose and fittings from a Mercury Dealer.

    And each hose is cut to a very specific (and very important) length. Reference the Service Manual, OR the Parts Catalog for appropriate lengths (see the "Bleed System").
