What goes here?

[surferdude345]

Im putting the stock exhuast back in the ski unfortinatly and i saw this and it looked like something should be here... Any ideas? Also could somebody post a pic of the stock cooling line set up?
Thanks

In case you can't tell from the pic - its the back of the exhaust manifold right by the drive shaft

thats where the flush kit goes. the only other line you need to hook up is the one below the one circled. that is the water comming from the pump.

but it looks like you need to plug it.. "brass 1/4 pipe thread plug ?"
