    Frank,
    If I may interject, What kind of vacuum is generated from the engine in the normal operation? Please educate me as well as what the cutout switch performs in it’s dutys.. I have never applied a vacuum gauge to an outboard…..has anyone performed this test? I would think with two big pistons at 4K would have a substantial reading….or not?
