Hose GTI 130

[SeaDooGTI130]

Just bought my first SeaDoo, a used GTI 130.
Found this unconnected hose, se pic.
It's clamped on top of the exhaust manifold.
Looks like a ventilation hose.
Anyone know what to do with it?

This appears to be the exhaust gas recirculating hose, taking unturned gases from the engine, and it connects to the intake air area, as shown in the third picture. There should be a nipple on the side of the air intake to connect the hose to. The air intake is under suction, as air is brought into the engine and these gasses get recirculated into the engine to be burned again.
