Iam running flap and ball scuppers in one tube

So I've maintaining my epic scupper since 2013, on my 5th rubber flap. Late last season hull was taking on water while floating at rest. I ride a deep water channel 35 to 50 feet deep plus with no where to park the ski so it's gotta float.

Inspecting the flap and door and holding the door shut revieled nothing... water still entering the engine bay. Later decided to remove the scupper flap and low and behold it tore up high above the hing point and behind everything while being hidden from view.

I replaced the rubber flap and again and rode. The big leaks was fixed but water still came in. But its back to a normal amount. Magnet is flat, rust cleaned off.

I really would not like this rubber flap to fail and sink my ski. So I decided to buy a ball scupper and run it along with the flap scupper. My theory is if the flap fails and rips off the ball scupper will come into play and save the day.

So a Freind told me he has to silicone his 2.5 ball scupper around the orings or it leaks. Mine is 2.0

So with that info I test fit the ball scupper. my tube has some lake film in it apparently cause low and behold the the orings around he scupper body only hit in 3 places around the inside of the tube. The tube appears to be slightly octagon shaped. Witness marks showed contact at 12 o'clock 7 o'clock and 5 o'clock 3 9 and 6 were clean.. so I removed oring and cut 2 the 12 inch strips of black tape and wrapped the oring s grove first then installed the orings. Added grease and when installing got complete sealing completely around the tube. Knocked it on n with a price of wood and small hammer and centered it and set the set screws. Stinger light checked from engine bay side no light.. all good, reinstalled the flap scupper and forgot about it..

Saturday went for a ride and what do you know absolutely no water leaking into my hull while resting, none at all. All day long none. Wtf Iam
So stoked

Not sure if the water can't just run down the tube because its blocked by the ball scupper body, "has to rise to get thru the small hole at the ball or if it's building up first and then then all seals it off. I'll
Have to check but it.

Running both works so awesome I can't believe it...

I thought about doing this but was worried the flap would let a trickle in that wouldn't be enough water pressure for the ball to stop it, so would be a constant slow leak. Just running versiplug and its 100x drier than my scupper.

If I don't forget I'll bring my stinger light and a mirror and see what the ball
Is doing Saturday. I wasn't expecting any change so Iam real suppressed.. if it's the ball still working with a flap in front of Iam real impressed lol.

I'm the friend who siliconed the versiplug lol. I have had 2 of the slide in oring plugs. Both versiplugs leaked past the oring. @Harbor tape and then oring idea is better then silicone but either way works good, way better than flap.

The day I installed the versiplug I had exhaust smoke in the hull, coincidence? Sucking smoke through the hole while riding slowly? So maybe the flap DOES have a purpose?
Going to find out over the weekend.

Also curious how the water doesn't slowly leak past the ball!

if the scupper just leaks a little how is this enough to push the ball back and seal the hole ?

Draining the water out of the ski does the flapper create backpressure between flapper and ball valve and then allows for a slower drain by pushing the ball back into the hole again ?

Just curious been fighting water for years now with different ideas...

Just a confirmation.. My versiplug does indeed draw smoke through the water at slow speeds causing smoke inside hull.

Installing the scupper flap made all smoke go away, but also caused versiplug to leak slightly.

I have different versiplug and scupper flap then @Harbor

So I tested alittle more today. I Removed the scupper flap completely and the ball scupper seals off completely while
Floating, no leaks still. Also
I have no leak between the ball scupper Body and the pcv tube.

Next I rode the ski in the 5pmh zone 100 yards at slow speed, noted engine started running slightly differerent, came
Back and pulled the hood off and after a few seconds exhaust smoke started coming out the engine bay, so @Jamo07sj my ball lets Smoke in at slow speeds too......

After restarting ski engine cleared out and ran normal again, fresh air haha

Flaps back on, works greats in combination for me....

Water bailing is the same as far as I can tell, never any water in hull that the bilge can pump out

No exhaust leaks, runs great, just wanted to see how the ball scupper worked on its own and if they can let smoke in the engine bay at slow slow speeds.

100% no exhaust leak. Ball lets in smoke at slow speed. We have ALOT of no wake zones in our area with no places to stop / all rip rap no beaches etc.

Flap serves no purpose as far as water blockage, but for me it completely stopped my smokey situation.

All I need to figure out is how to make the flap leak more to make the ball functional, while still preventing smoke.

Maybe we have longer no wake zones then most so most other people never have an issue. Me and @Harbor also have dasas maybe that makes a difference since more hungry for air??

Either way harbor said try the flap I said ok what the heck. The look on my face when I saw no smoke... Lol

Hmm tough call with the versi letting in smoke. Just a small one or full size rickter versi let in smoke?

In my Non rickter hull, The PWC doctor 2 inch Versi with white
Ball, let In smoke in no wake zone speed situations.

The one jamo07sj has is the maniac 2.5 And it has a rubber ball. Both are letting smoke.

For your rickter I'd prolly try the OVP since it has a plastic ball and you don't have to knock the scupper ring off the hull. Try reinstalling the scupper flap and see how much water (if any) the ball lets in and if you can live with it.

Be sure to make sure the orings are are touching and leaving a witness mark all the way around the inside of the pvc tube. You'll prolly have some lake scum in the tube the orings will wipe clean only where they touch. My pvc tube is not exactly round I found out. Octogon shaped. They store pvc tube in racks all stacked up with pvc on all sides, wonder if the weight of all the other pvc tubes is slightly changing the shape of the pvc.

After reading some of your other posts, I may have misunderstood your question on the small versi plug.

I have 2 small versi plugs in my tray for tray drains. In no wake zones they let water back flow into my tray. In a 100 or 150 yards no wake my tray is full and the ski is lisping/sinking in rear. I've added the thrust mini drains into the versi drains aluminum housing and reduced back flow by about 75%.

My point is if the balls open and allowing water in it could also let smoke in but my guess is it would be a lot less...you might look at the thrust mini for your fixed flap.
