Water in hull

 Hey guys, Im pretty new to jetski fishing and have noticed that my 08 waverunner deluxe is filling with quite a bit of water when I anchor up or drift.

There is no problem with the bungs and I cant see any structural damage to the outside of the hull. Basically when i stop driving for more than an hour or so it fills up.

I'm just wondering if this is a design feature or if i have a problem? It seems as though driving it after fishing seems to gradually pump the water out?

Problem might not actually be the bungs but the sockets they screw in to. Pull them out and reseal then screw them back in.

My problem was a hose part of the cooling system popped off the right side of the engine about half way down filling the hull while the engine was on only. Pretty sure its 3 hoses all part of the cooling system all entering engine next to each other. Be sure to check under the lip of the bumper guard around the whole outside of the ski, my mate had a crack the length of the whole ski from nose to tail. that doesn't really match up with the water emptying out under way though, unless you have a bilge pump?

Thanks for the suggestions

Thanks for the suggestions guys, Ill do a more thorough check of the outside and reseal the bung sockets.

But yeah its definitely only when im stopped. The bilge pump empties it out as im driving but its not healthy as I can only go about 10kmph max full throttle for a good five minutes, not to mention the potential saltwater damage to the engine.

I was just wondering if it was normal for it to fill up or if I have a problem, apparently i do :(

Definitely not normal. If you cant find the problem out of the water might be an idea to head down to a quiet ramp on a quiet day and hold the ski on the water at the bottom of the ramp with the seats off to see if you can see where the water is coming in. Your next problm will be the saltwater corrosion inside of the hull, if you decide to get the leak fixed be sure to get all the hose clamps replaced as they'll be the first to deteriorate and you'll have the same problem I did

 Before you go spending your hard earned cash- and you will pay a couple of hundred dollars for them to find the leak.  Do as Beau has suggested. If you are getting that much water in the hull,you will see where it is coming from.

Also do a search on "Waverunner getting water in Hull".    Looks like the reverese grate is a common issue. There's heaps of info and fixes to check first.

Good luck with it.

 Hi mate, i had this happen

 Hi mate, i had this happen to me on my  08 VX deluxe, the issue was with the pump housing. the guys at jet power said it happens because the glue they use to seal the pump housing, the best thing for you to do would be to fill you hull with fresh water and see it coming out near the pump housing. i took mine straight into jet power to get fixed. not a cheap repair as they take the motor out to fix it. deff worth while getting all hoses and clamps replaced when they fix it. i hope it is not this issue but sounds the same. i have no isses since been fixed i have also installed a bilge now.

^Was reseaching it last night and a lot of people have had that same problem with the vx110's. Just filled mine up and it looks like thats the problem (it was leaking out of the intake grate). Ill still take it to the ramp to make sure though.

Can I ask how much I should expect to pay roughly if that's the problem? and how much would replacing the pumps and clamps cost? I'm a broke uni student haha.
