SCUPPERS SCUPPERS SCUPPERS!!!!!I need your help!

[Bushwacker]

If you're concerned about self-bailing at rest, Gillie's right, the scuppers out the back with the ping-pong ball check valves work well, although debris can keep the balls from sealing.

However, if you're worried about quickly removing a large volume of water from taking a wave over the bow in what may be a boat with low freeboard (maybe a flats boat?!), I think the suction in the vertical SeaCraft type scuppers with the wedge forward of the exit will beat gravity every time! The SeaCraft scuppers are about 1" ID; going larger would also help. And if you go with vertical scuppers, make sure you can get rubber plugs for them, because you need the plugs unless your deck is several inches above the waterline!

This is something that butters my biscuits. Having fished on some commercial boats, I always shake my head in dismay when I look at new "small craft" and think to myself.....have any of your designers EVER taken green water in a small boat? Really, you think those scuppers are gonna save my bacon?

I don`t see scuppers on Wagons, I see CULVERTS. Things that can actually move water. What a concept.

As Gillie said, you must determine if they have a proper angle to allow gravity to slowly do its job.

Do you have water coming in at rest?

With 1 or two in the corner?

Do you have a heavy motah on the back?

We need more intel.

Do you have corrugated scupper lines or smooth hose?

Do you have flappers?

Have you called the factory?

I have thought about puttin` big honkin` oval scuppers in my rig.

Hummm........Sandy, I'm thinking 3"x 6" oval would do the trick. Don't want to go too big because the bugs you catch and toss in the boat from your super secret lobster spots, while using your new Lloyd Bridges approved scuba gear, would slip right back out through the scuppers.

I`m building a Hedonism resort for them. Bugz check in, but they dont check out.

Bud, get the launch.

Don't worry we'll leave the light on for ya!

Wow thanks for the responses! I though you guys had given up on me.

The boat is a Sea Hunt BX22 with a F150 stroke so its not rated for maximum HP which I believe is 200 or 250 HP.

As you can see in the video the thru hull exit is right at the boot stripe which depending on where someone is standing may or may not be underwater.

There is not much elevation difference between the existing thru hull and the existing horizontal scupper. Bottom line is there is nothing in that configuration I wish to reuse. It will be used to augment my scupper modification.

This is what a figured out and what someone else told me - Basically horizontal scuppers (the kind that I have only work at their FULL capacity when the water level is about the top lip, which is a lot of water in my case.

However vertical scuppers always work at the full capacity as long as the lip is below the draining water which is always the case.

Its all about water levels and equilibrium. I probably have 3 inches between my deck and the water level outside the boat. But as long as i have some distance there, the water will still drain with vertical scuppers.

I dont mind wet feet and get that now anyway. water can come in and water can go, but when I go (hit the throttle) I want the water gone and crud with it.

So after looking at tons of 90 degree vertical scuppers, none are going to work since I am hampered by clearance underneath where the scupper would go. Right now I am sizing out pvc for some sort of the custom fit. The discharge would be a new thrull hull on the bottom of the boat.

I am thinking of something liek this. The L piece on the right but I got to figure a way to keep it snug with the deck and I wish the wall thickness was a little better.

Take that cheap ass crap back where you bought it.
