    A great idea for sure. But, keep in mind that an exhaust leak into the water pump wouldn’t show up with the "drill test". True, it might show up if you pick the gearcase up to expose the water pump once it is primed, but that is kind of a tricky thing to do.
    One thing is for sure though. You have definite pump problems if nothing flows out of a copper tube during this test.
