if you were in Florida with 90 deg water use all 4 outlets over board.
I have my center 2 plugged, water around here is 65 to 75 ish and The engine after break in will only reach about 105 deg...I still have to use 2.73mm or smaller restricters in my 2 outlets to get up 130 deg flat watet type riding..,
You can also use Y fittings and run 2 off the head to one over board, do the same for rear cylinder...
If you have 4 holes in your hull for pissers already you could run all 4 out and check you engine temp after break in, if too cold you could use restricters to get it to warm up..
Iam usually around 135 deg
