Is that the way the lines were routed when you got it?

I can't expand the pic, but it looks like you have two of the headpipe fittings going back to the head. I'd use this drawing, and just run the extra fitting you have on your head to a pisser instead of plugging it. I also put a tee in the line going to the stinger with the tee going to another pisser.

Pic is too small to tell anything.

I had one of those, and they're completely different than a b-pipe. There is a water jacket between the manifold and headpipe. The mating surface looks like the pic I attached.(I can't draw very good either) So the head pipe gets water directly from the manifold and the head. I don't know if both holes connect to all 3 fittings on the headpipe or if they are separate water jackets. The manifold also feeds water to the cylinders like every other exhaust. I only had single cooling, so I ran the lines like the pic I posted a few threads up. The only thing I did different was put a tee in the line going to the stinger for a pisser to dry the waterbox out a little. For dual cooling I would just run the other line off the head to another pisser, and make sure you have good pressure coming out both of them. Then adjust restrictors to get the water temp where you want it.

650 coffman dual cooling
Hi ,
I hooked the lines up like shown on my picture but the second pisser would not piss at all.....sigh
This could be because I used the bildge hole as second line, the hole is very big should I block it off or run it out,basically leave it and then tap the pump with a smaller hole like the normal cooling ?

Which pisser isn't working? The one off the head or the tee to the stinger? I wouldn't connect those two fittings on the head back together like that. Take one to another pisser, and the other back to the head.
If the bilge outlet is still hooked up like stock then that definitely won't work as a cooling line. It sucks water out. It won't force water in. You need to tap the pump for a new fitting.

coffmans waterlines......I know I am annoying :0)
Hi ,
I am lost.....sigh
Bildge is blocked, new line taped in pump.....lets get this straight.....
>> Dual cooling << Head has 2 outlets NOTE "" HEAD PIPE 3 outlets...""
2 Lines from Hull >> both into the exhaust manifold ( has to inlets ). CLEAR
Then different versions offered...
A) Front Head to pisser/ Front Head Pipe to Stinger T to pisser control valve after pisser to stinger /Back head to low Head Pipe/ block second head pipe outlet ???
B) Front Head to pisser T into front Head pipe/ Back head pipe to Stinger/ Back head to second front head pipe T to pisser.
C) Front Head to pisser /both front Head pipe T the to back Head/
Back head pipe to Stinger T to pisser.
Thank you for your help !

run the rear head fitting on the head out.
run the front head fitting to the header's front 90' fitting.
the 90' fitting on the rear of the header goes to the stinger-end of the pipe body.
that can be t'd into the stock rubber fitting.
if you dont t off the stinger line, the 3rd fitting on the header that goes straight up can be used for the rubber 90' fitting, but i would just block it off until you get it wet and make sure evertything is good.
if you use both water lines from the pump, you may have too much water going through the motor and pipe and it wont rev up.
good luck
