EPIC scupper sunk my ski

I have a new fs2 evo coming in like a week or two. I have never run a scupper valve but am starting to think I should plug it from the get go and just run bilges. Anybody have any idea how long it would take for this ski to sink if left up side down? Do I have a minute or so to flip it back over?

Put loctite on the screws of your Rickter scupper, right off the start.

I've seen a Rickter Evo get flipped and sink in 15 seconds. Think about it the ski will sink as fast as the air can come out and with a big 2 inch hole the air can come out really fast. If you plug the hole where's the air going to go?

If it doesn't seal itself on land it sure wont seal itself with water trying to get in.

Mine doesn't come close to sealing on land, but when I drop the ski in the water, I always put my hand against it and it is tightly pushed against the sealing surface. Mine leaks a little like most of them, but I would certainly say it is sealing as tight as it can.

and my 2cents on the subject: Scuppers are great, but scary. They must be checked frequently (for me everytime I drop in I make sure its sealing). On that note, I do not have a bilge, but I keep my buddies and a tow rope close. I ride flatwater only.

And FWIW one way valves have their issues too....God forbid something comes off in your ski (gas tank check valve @%^$&$%^$@) and it goes directly in toy our 1 way valve locking it open for the entire damn lake to get in!

My gas tank check valve now has a safety strap on it!

I use scupper on flat days or days with predictable waves.
On large wave days or days I am going to leave ski floating, I plug it.

This takes 30 seconds to take the plug in and out.

I have a solution to the scupper issue and am going to design it this winter. It is 99% done, in my head. I am POSITIVE it will stop skis from sinking due to scuppers, but still let the water out.

We have ran most kinds of scuppers...and. from our experience. The epic scupper works awesome compared to the rest ...but. like any scupper it needs to be checked... most after market hulls come with a scupper...and the ones they come with leak like crazy...that's our 2 cents...epic magnetic scuppers (#1). Not saying there isn't other options but scupper vs scupper...its the best

Like I said earlier, the magnets cause corrosion and will bulge out and cause a the valve to not seal properly. Maybe that was a bad one because I have not seen but one. Just pointing out that there is possible issue with that part in salt water. Other than that looks well built and love the idea.
 
I checked my Epic scupper a few weeks ago after running it over the summer. The rubber piece was torn on the sides and probably wouldn't have lasted much longer. Luckly Epic had included a spare with it so I was able to swap it out quickly. For my next ski I'm going to run a large Versi-plug with a removable screen in the engine bay to prevent debris from clogging it and holding it open.
 
IMG_20140419_181305_247.jpg I didn't think the recess the scupper, mine is flush with the back of mine on one side and inside on the pump tunnel on the exhaust side. What would be the best way to protect the other side, glue a pvc pipe around it an inch out? BTW I have a sxr based ski wet layup no foam.

If everyone filled the rest of the motor compartment with pool noodles no skis will ever sink. 1 noodle can float a 200lb man so slip two noodles in your ski and bam no chance to sink ever.

It's going to take more than two noodles to keep a ski afloat, the human body is much more buoyant than motor and pump. One noodle will not keep a 200 lb motor afloat ( motor weight just an example). The entire nose area and on each side of the motor are stuffed in mine.20140407_091230.jpg
 
Yes, Buoyancy of the body is totally different than an 80 pound engine plus other completely solid metal parts in a ski. Straddle a pool noodle in the water...take a deep breath and watch you float up...breath out you will sink down to your neck. It's not that simple for your ski. If you wanna not lose a ski in surf every void possible should be foamed in your ski.

Has anybody ever layed two-part underneath their railes? Or even just cut a noodle in half and tack it in with some weldwood under the bond rails?
 
useful info from another board:

1 Liter or 1000cc (or ml) equals 1 kg or about 2.2 lbs. We're going to use 1 foot of showtime's 3.5" diameter noodle. Converting this to metric we use 1"=2.54cm. So, the noodle is 30.48cm long by 8.89cm in diameter.

Here goes: volume of a cylinder=pi(r)(r)(length)or 22/7 X 4.445cm X 4.445cm X 30.48cm = 1892.7cc or 1.89L

Converting the weight of 1.89L of water back to pounds is 1.89kg X 2.2=4.16 lbs. This does not take into account the hole going down the length of the noodle! In other words, the noodle will actually support a little less than 4.16 lbs!

So.......1 foot of 3.5" diameter pool noodle should float about a 4lb piece of metal on top of the noodle.
 
I think a closed cell foam (the blue one that comes in sheets) tightly fitted in the tray area is a must for any standup ski. I've seen a good old square nose floating with the tray up in huge gnarly surf for well over 30min until the waves pushed it to the shore. Even though hood was detached, the ski never sunk . As long as the ski bobs like the good old square nose, it is salvageable.
A/M ski builders should take this in consideration.

Interesting, my scuppers are original Wamiltons from 2000! Yes they leak some, ok a lot but the work. Honestly Wamiltons makes some of the best products.
