. If you can't make anything else work, just cut a motor plate to fit. I wish I knew more about using the bottom holes only??? I use a full plate and get the full strength of using the H2O pump holes. I know people have used flat stock before instead of an actual plate or ears, but at my power, I would never even consider it. Maybe a full plate, cut around the H2O pump and use the bottom 2 holes and maybe a head hole??? .
