I posted this in the General forum, but I always like specifically asking here because everyone here is so helpful.

In that post I attached two pictures. My 191 has what is in the first picture, except that there are two spray heads, not one like in the picture. I am adding pump out in one way or another. I have to replace the drain valve because one of the barb fitting on it broke, so that's why I was considering a different valve like the Flow Rite System 3. The catch is that I have to plug one 3/4 thru hull hole if I switch it to system 3, which only uses 2 through hulls. Any thoughts? Worth changing things or no?
