Help! jetski fills up with water.

Hi, totaly new to jetskis but bougt myself a superjet 05. thing is it fills up with water nothing wrong with that i guess since im balling ;D. but it dosent come out. ive seen that greay box in the back of the engin room, how does it work? tryed to blow in it and it comes out just next to the jetbeam. so nothing is stuck but still dosent feel like this box taking out much water. so question is what could be wrong? nice to see that there are some forums around and plz excuse my bad english ;D /niklas

Yes, that uses suction pressure from the pump to pull water out of the hull. It is not the fastest in the world so you need to just cruise around a couple minutes when the hull fills up with water to let it work.
 
Have you tried running it in the water with the hood off? It is possible that one of your cooling lines has a leak or is not hooked up. If you don't see water pumping into the hull when you do that then it is just an issue with your bilge.
 
thanks for the awnsers! will run it with the hood of tomorrow, but that bilge you linked isent that the one you have in the middle? or could i move that to the back instead?

make sure the other end of the hose is connected to the reduction nozzle.

see the hose thats not connected to the nipple? thats the siphon bilge.
 
Does it fill up just sitting in the water or does it fill up while riding? Your stock bilge may be clogged.

Sorry for the thread jacking here. But my SN takes on a lot of water too. Only when it's parked though. I have a couple pisser's that are half ass blocked off and sealed, but those aren't bringing in as much water as I'm taking in.
I'd say it sits for half hour 40 min and pisses a good 30 seconds of steady stream. I feel it's gotta be something with the exhaust maybe? Since it only does it whIle it's sitting..
I dunno if having a dry pipe system has anything to do with it.
But I've got the 701 dual carb. Plenty of other goodies as well.

You went way back in time for this one. Lol
It could be a few things. The two main things I would look at it is one the midshaft and two the water lines. If the seal is bad where it seals to the hull it will let water in while sitting in water. Also look at all your water lines especially the ones that are low in the hull. The best thing to do is back it in the water while it's still secured to the trailer. First just look inside the hull and see if water is coming in through the midshaft or anywhere else. Then run it and see if you can spot a leak somewhere.

I have notied that where the driveshaft comes through the hull, right above the intake grate, has a small chunk of what looks like a seal, missing on the lower section.
Could that possibly be a culprit?
I'll post a picture when I get it loaded up this morning.
I still need to build a cart for my hitch hauler, right now I have it sitting on a plastic pallet. Lol

That could very well be the culprit.

@JetManiac On here is the one stop shop for anything you need. Along with uber fast shipping, Just PM him

I concur. He has the best customer service out there and seems to have every part imaginable. Wizzards Powersports is a good place to find good used OEM parts as well.
As far as a shop manual is concerned, you may be able to do a google search and find one you can download.
 
If hull takes on water while off, also check this 90 deg. fitting. It is a vacuum break for the stock syphon. If that hole (#69 drill bit=0.0292") should be clogged, the hull may well take on water while stationary.P1020766.JPG

Tilt it back on the trailer and fill it up with the water hose until the midshaft housing is fully covered. If it's leaking, you will know.
