Changing my triple pipe water routing
I'm trying to get rid of some of the pissers on my boat and also want to change the location of them. Right now, there are 5 grouped on the back right, and they cause the footwell to fill up with hot water, when idling. 2 are from the head (aftermarket) and 3 are from the pipes. I would ideally like to pipe the (2) 3/8" lines from the head to the stock pissers up front, under the rub rail...but I have concerns that they may be a little small, even though mine are currently going through 3/8" 90* pissers, as specified by Speedwerx. If they won't flow enough (they have a slightly smaller outlet than the Factory Pipe type), then I'd like to split the front head outlet to the two pissers, and pipe the rear outlet through the stock outlet in the transom. Any thoughts?

On my old tripple I used all stock outlets for the pipes and only dumped maybe two heads over board. Others have done the same.

So do you think the two stock outlets up front flow enough to exhaust all of the engines cooling water?

Looking at this again. Will the 2 stock pissers up front flow enough water to dump the entire engine cooling through them? I want to hook the 2 outlets on the head to these two outlets (I will send the pipe water through 3 pissers out back). I also have to be careful to keep the water pressure in the motor low enough so that it doesn't push past the head o rings, into the cylinders...they don't seal as well as a gasket. Ideally, I'd like to switch to 1/2" cooling lines, but then I'd need 1/2" pissers.
