Need some help please 1998 gp1200 /bought set of used triple pipes,Got instructions from factory pipe .On my water manifold there is an extra fitting in the end ,not illustrated in the directions.factory says this is just and extra cooling line ,but didnt tell me where to hook it in to.Any body know

That extra slot is for dual cooling. You need a second cooling line coming from the pump area. I believe Riva sells the blocks that go into the pump area or you can drill and tap it out. I can not remember what it was that I did in order to run the second cooling line into my 97 when I had it.

With my 97 1200 I just plugged the line coming off the end of the filter and instead of running the exit lines out of the pipes to the exit hose on the pump I ran them through squirters which I mounted on the front side of my ski so I could see the flow of the water. Then you know your pipes are getting water I have 5 squirters total.
