I finally got around to doing this to my 75-2 yesterday and the hardest part to me was getting the plastic all put back and getting the lower screws started back, but overall an easy job and IMO the absolute best video/tutorial on how to do this, thank you for making this video.
I drilled 1 on top and 1 on the bottom, I then fitted Boat Drain plugs. I think the Freeze Plugs Joey used is a good idea as well. I think I will also drill Holes in the Plastic Covers as well so you don't have to remove them.
