    repost waterbox question... =)

    hi, tested my slx 780 yesterday



    and i found out that my waterbox is too hot when i just run the skii for a minute, so what i did, i removed the strainer on the pilot of the exhaust pipe, and cleaned it, and also the leaking hose at the bottom of the exhaust manifold, and observed again, water comes out of the pilot already but im not sure if it is sufficient for the waterbox to cool down, so how hot should the waterbox be? can be touch by hand? for seconds?

    The hottest part under your seat should be your cylinders/heads. If your waterbox is getting hotter than that, you likely have an issue.

    Just make sure that your cooling system is flowing properly and not plugged up anywhere, along with your (hoses and all).

    As long as your box isn't way hotter than your engine/exhaust, and not melting hoses, and your cooling is flowing, I wouldn't worry about it.

    I have the same issue, waterbox is hot and burns my hand. The cylinders are all just warm. From my searches it sounds like the 780 exhaust runs hotter. What is the "normal" temperature of the water box on a 780?

    Check your filter screen located at the top of the pipe. (hose is connected to it)

    I took the screen out and it was clean. The orifice was also clear. I ran it with the hose off and a stream of water flows from the orifice. Took it for a ride for about 15 min. and touched the muffler and burned my hand. But the cylinders are warm (I can keep my hand on them). Any ideas?
