exhaust pipe connects to the exhaust manifold, which connects to the main engine.
The exhaust valves are the hottest component of the exhaust system of an internal combustion engine.
Exhaust
I would say it is the exhaust system.
The exhaust system is what muffles the engine sound keeps the fumes out of vehicle and away from the vehicles occupants and also filters the exhaust fumes out.

the oxegen sensor on most cars is usually located either in one of the exhaust manifolds or someware in the exhaust system
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
A blocked water box will prevent water from flowing into the exhaust system. Because jet skis have a fully-enclosed engine space, cooling of the exhaust system is vital to prevent overheating. With no cooling water flowing into the exhaust system, the exhaust system will overheat. Exactly what happens depends on the model and to some extent on luck. But usually one of the exhaust connections will burn through, causing exhaust to leak into the bilge.
I would say it is the exhaust system.
That is condensation due to the exhaust system being cold and the heat from the engine makes the exhaust system / pipes sweat. As the exhaust system heats up then that will stop. Now you said WATER not antifreeze. If you had engine coolant running out of the exhaust then it would be the color of the antifreeze and it would be steaming WHITE and then you would have an engine problem, MAYJOR. You said water. Drive it you have no problems. That is normal.
