type 4 water routing

[Officer Mike]

this is what i think that i am supposed to do.. let me know what you guys think. also i havent decided to go with dual cooling or not.. should i?

dual cooling:

1 tap the pump run it through stock bildge
2 run one line to the bottom of the manifold (bigger of two holes?)
3 second line (drill tap the top of manifold) put line there
4 from the fitting on the bottom of pipe by coupler to the back fittnng on ADA head
5 i kno connect the two on the pipe.. run a mikuni jet in the stinger side.
6. back side of head outboard
7. last fitting by stinger outboard

is this right?

and for single cooling is it the same, just minus the second in on the drilled/tapped manifold in?

thanks guys

My dual cooling for type 4 is...........

in to bottom of manifold
in to bottom of pipe

out head to pisser
out head to pisser
(jet in stinger) out stinger to pisser

Has worked well for me.

 

[Officer Mike]

both the heads are outs? so then the water gets into the block through the exhaust man?

Yup, one off the head over the side, the other to the back of the pipe.

Up until this year I have ran mine the following way. I ran this set up year around in the North West with no restrictors and water temps down to the high 30s with no problems.

Dual lines from the pump.
1 to the exhaust manifold
1 to the exhaust chamber.
2 from the head over board.
1 from the sting over board.

But because everyone is so worried about cold seizures with this set up. I tried switching it around.

1 line from the pump.
1 to the exhaust manifold
The head teed with 1 line to the exhaust chmaber.
1 from the stinger over board.

1 line from the pump.
1 to the exhaust manifold
1 from the head over board.
1 from the head to the exhaust chamber.
1 from the stinger over board.

This is how I ended up.
Dual lines from the pump.
1 to the exhaust manifold.
1 to the exhaust chamber.
The head teed with 1 line over board.
1 from the stinger over board.

With these four different set ups I noticed no performance gains or losses. I did notice my engine ran a little warmer with set up number two during the winter other than that nothing.
On a side note I have had my cooling line plug twice with set up number 2 and 3 but never with 1 and 4

Just an observation Kevin, if you loose your cooling water to the motor you are toast. I always like a 2nd line cooling the cylinders, just in the event one plugs.

 

[crashski]

Yeah I know. I always watch my pissers when I start the ski and after its been beached. With two different cooling lines it’s varying clear quickly if a line is plugged. With running dual lines to one point you can have a line plugged and never know it until the other line gets plugged.

thanks guys.. i appreciate it. anyone have any other suggestions?
