    Water pressure connection point 150 4 stroke

    S/N 2B129959 repowered friends boat from a 2.5L to a 150 4 stroke and couldn't find a connection point for water pressure gauge connection where the heck is it?
    Also ignition switch is flaky is part number 87-88107A 5 the correct switch now that he doesn't need push to choke?

    Where is his keyswitch mounted (in control, on dash), and if on dash, how are the wires connected (molded in, ring terminals, push-on terminals)?

    The above image shows how water pressure (analog) is connected.

    A 90-degree legris fitting is also available, Part# 840908
