Your 7 minute time sounds a bit slow. Mine was a not too far off the rating with the normal thru-hull fitting. Before drilling, just pull the pipe off the thru-hull and test it with the pipe opening at the same height as the hull. That will show the time for thru-hull with no thru-hull constriction. If it speeds up things significantly, then you might get part of that result with a drilled out thru-hull. Your pipe looked corrugated in the photo, like the flexible, thin wall stuff some use for boat plumbing. I used the straight-sided clear vinyl type. That might also have an effect on the flow, especially since the loop you use makes it longer than mine.
