Suck gate for x-25. Anyone using one. The stepped hull makes it tough

Has anyone made a suck gate for use in an x25? The stepped hull makes it pretty tough to get one fully submerged. I made one that is very offset (made two actually because they are now different for stbd and port since not symmetrical). But the only way they want to stay in is at about a 45 degree angle downward since all the pressure is on the bottom of the gate and it rotates it around the front suction cup. You can see what I'm talking about in the pictures. The water pressure pushes the back cup all the way to the next groove in the hull making it almost more like a tab than a suck gate. This is the wave it produces (pics below) with just rear ballast hard tanks and a 750 sac above each tank and just me in the boat. Planing out becomes hard with many more in the boat. Still surfable. Just wondering what others have done. I would love to be able to use a symmetrical one and not carry two with me.

A couple things I'd suggest:
  • Ditch the plastic handle
  • Drill drain holes behind the suction cups

Plastic handle doesn't have near the holding power as the aluminum handles on amazon. Update to the better handle and I think that will help a lot with keep it from rotating.

Additionally, to get a better hold, drill some holes to allow the water to escape from behind the suction cups. You'd drill a couple holes on the flat part of the suction cup housing (on either side of the latch to tight the suction cups). Just having holes that allow you to look through the handle piece and see the back side of the suction cups allows water to escape from there that would otherwise cause a softer hold with your suction cups.

I think those two things will help you dramatically.

We surf all the time on my friend's 2013 X25 with a homemade suck gate. He has two plastic handles with one 90 degrees off the other. He only attaches three of the four suction cups. So yeah, it can be done and yes it certainly is a pain with all the contours on that hull.

Mission Delta

We use a Mission Delta on our 2011. Haven't done anything beyond stock hard tank ballast. Found 11.6 produced the best wave with that setup. We're not done working on the setup but this is what we've gotten so far. BTW, my son is 6'3".

You guys just need enough weight to get that thing under water while you're sitting there. It'll be great then.

How do you get that mission Delta under water with stock ballast?!? I have 1500 more lb and still have a tough time getting mine under.

@keith2230 id love to see some pics of that setup I may try replicate it.

I want to see how a gate works as an actual gate for delayed convergence and not turned to a 45 making it more of a trim tab just listing the boat.

No doubt. The guys at Mission suggested an 850 lb sac on the floor or back seats.

We just got the boat so lots to figure out...

It's definitely underwater once we're underway.

That wave doesn't look too bad. I have 1500 extra pounds in the back so I should be able to get a gate of that size underwater. Ill try build one like the mission delta and give it a shot.
