Super Jet I'm confused with my waterbox..

Your waterbox is mostly cooled by the water entering your stinger, correct? I should probably ask Zack this but maybe you guys could tell me the ideal role a FCV should have? I understand that it varies from ski to ski due to everybody's water pressure being different. Is the goal for it to prevent water from loading up the box at idle/low rpms? Or is the goal to run the waterbox as dry as possible but at the same time to provide only as much water as it takes to keep it from overheating?
The Fcv delays the water entering the box based on adjustment, once open flow is normal. Like you've mentioned, it's roll is to keep the box from loading with water at low rpm's when heat created by the engine is lower.....low rpm, low exhaust flow, lower amount of heat.
A second restricter after the Fcv such as a jet or seat limits amount of water to box once the Fcv is open. So the goals you mentioned are handled by different parts.
On my skis when I remove them from the water and dry the exhaust I barley get any water out the tail pipe, I run just the Fcv.... On my old limited my friend now owned, the water flow out the exhaust tube is large, the diameter of the tube, it's a large flow before it clears, he has no Fcv.

Alright that's exactly what I thought, but I'd say I could use a little insight on when yours opens in terms of throttle placement, not rpms. Just a ballpark. My ski is pretty snappy right now but I'm not sure on enough flow, but I think my waterbox only overheated once when I had absolutely no water going in it.
Haha I see!
Drilled each cracks end out with a small bit, then did 2 layers of biax over that whole side, one being a little smaller that didn't overlap the seam. Also sealed all seams, inlet and outlets, and all rivets with thickened epoxy. Should work fine for a while now!
