Super Jet dual cooling lines Super Jet

This is how i have my pipe set up. does this look right. havent ran it yet, just just finished the build and have to tune the carbs.

I ran seperate circuits like that for almost 2 yrs with no problems, then I put both lines into the exhaust mani for the cyls to run cooler in Florida 90 degree water and 200psi on pump gas...one benefit to your set up is you can backflush cyls fully without motor running...

Where's the best place to run a through hull tube for dual cooling on a SN? Keeping stock bilge and running a trim tube in the upper left corner depending on position of trim ring. Do people run a cooling tube on the steering side? If so do you make a bend in the tray area so the two lines come out on the left middle side of the Bluckhead near the mani? Or just put everything on the left and run the tubes straight? Any tips or knowledge on this would be awesome!!!! Spend a lot of time on this forum and can't seem to find any specifics.

i run just like that. I Y my head lines together so i only use one pisser for the motor, and i have a flow control thermostat after my exhaust cooling to slow the water down and get the pipe hot. With my pipe my stinger is closed off so it only gets water from the headpipe. The exhaust has a pisser for it so i can watch my motor and exhaust cooling circuits while i ride.

I know people get worried about a plugged line, but the chances of that happening are slim if you dont beach, and fine sand will get blown through the system and out with the PSI the pump puts out. and you can see it while riding, if it plugs shut it down. I like cold water into the pipe, it seems to make more HP.

That's actually called parallel cooking and there is nothing wrong with it. Only thing to consider is that if you have one line to the motor from the pump and 2 lines off the head with a am o ring head that your cooking could go through the motor too fast. You may want to consider wyeing the lines off the head together to one pisser to slow the water back down and build pressure in the cylinder, or you could keep 2 pissers of a smaller diameter or inline restrictor to do the same thing. It's also not a bad idea to tap the manifold for dual cooling and she the one line in to feed the manifold more evenly. You might be depriving your rear cylinder of water.
