Outback V GI to GIII Ballast Upgrade

Besides cutting the scupper of the stock intake, I also shortened it:



The stock intake was way to long for my liking. I wanted the new pump to be as low in the boat as possible. As you can see in the pic, the thread for the flange nut ends just above it, and the tapered 3/4" pipe thread starts there. I used a bench grinder to grind down the O.D. to the required diameter needed for the pipe thread. I then cut new pipe threads with a pipe threading die. I also ran a drill up the center to open up the I.D. and clean up the casting.

Here are the three new Tsnumai 800 aerator pumps:
