On most gear cases, when they start to operate, the gears want to try to move apart. In modern gear cases, where the pinion gear is fastened to the drive shaft, the whole drive shaft lifts up. I’m not that familiar with your gear case but I am wondering if maybe that is designed to happen in yours, too? That might lift the impeller to a good operating height?

Long live American manufacturing!
