Question about water box regulator valve o-ring?

[Rossterman]

Was leaking water out of the weep hole. Disassembled the cover and valve and found that the large clamp had backed off and unscrewed. Diaphram was worn but appears to be no hole yet from the metal spring clamp. Replaced it with a SS wire tie. Assembled everything back together and still was leaking out the weep hole. Was noticing that there seems to be no seal between the plastic part connected to the diaphram and the bore of the body. Looks like there needs to be a way to prevent water coming past the bore. I figured the groove marked in the pic was supposed to have a o-ring to do that. Added one and some grease and reassembled and no leak. Just wanted to verify that’s the way it's supposed to work? If not, what am I missing?

I had the same issue. I replace the rubber diaphragm and it still leaked out of the hole. What I end up having to do was to replace the bottom plastic section (the area that the part you are showing goes in) as mine was worn and that is why it was leaking. Purchased a used one and it works great, no leaks.

Well, there is no o-ring there from the factory and tha's just how it is. It's the outer body that distorts and will not seal so you need to replace the entire body with a new one and as far as I know only OSD seadoo sells them now.

Having said that, I know some members here have installed an o-ring into that groove and report no leaks or problems but the jury is still out on whether this is ok or not since the factory did not put one on it.

Yes mine is working fine a year later after adding an oring there to stop the leaking "feeder block"

Hopefully the o ring is one of those things the engineers speced and the bean counters eliminated.

Obviously not related to this seadoo issue but I saw an interesting use of the rave valve technology on a KTM 500 aftermarket conversion:

Take a look at all the aftermarket big bores for the Yamaha 701 based engines used in the big buck standups, they all use the seadoo RAVE valve.
