cooling and exhaust system help 96 xp

[benj15]

Not too sure what to call this, it is shown under the cooling system section in my manual.

On my xp the hose from the lowest point of the hull under the engine, runs to the exhaust hose right before the threw hull looks like its gummed up with slug and sand almost have way the length of the hose. Is this hose only use to let excess water from the hull out while the engine is not running?

Any help would be appreciated, thats all i can think of for the use of the hose and my seadoo is always on a trailer i wouldn't worry about it untill winter. I have about 3 weeks left. I just want to make your its a problem that can wait a few weeks of running before i clean it out.

Another question. what would be the easiest way to clean it out. i wont be able to reach where the hose attaches under the engine
