I have come to the experts. The best of the best.
I posted my problem on The Hull Truth....Nobody would touch it with a 10 foot pole. http://www.thehulltruth.com/boating-...ication.html#b I posted on the Sea Hunt owners group. No concrete responses. http://seahuntownersgroup.yuku.com/t...VING-ME-INSANE Its time to get serious. Video here: http://www.youtube.com/wa...5n1ae4I&feature=youtu.be I own a Sea Hunt BX 22 with scuppers that are horizontal and is terribly slow to drain. I want install scuppers that are vertical like the ones from TH marine. Any tips? ![]() |

Have you contacted Sea Hunt about this issue? They might be able to give you some suggestions. The vertical placement seems to be contributing to your problem, and I wonder what size your drain hoses are? I have two boats with floor drains and they drain freely. Do you have access to your drain lines? I would write to Sea Hunt @ 2348 Shop Road, Columbia, S.C. 29201 or call them @803.755.6539 and get their input on the problem. If they can't help, then I'd start thinking about alternate solutions. Additionally, Is it possible that you have some debris clogging the drain hoses? I would flush each line out with a garden hose held right up against the drain and see if you clear any debris out. I do it a couple of times a season because of leaves or other small debris that find their way past the scuppers.

The key to the good performance of the vertical SeaCraft scuppers is a wedge thats about 1/4" tall right in front of the scupper outlet, shown in picture below. It creates a significant amount of suction that really pulls the water out when you're up on plane. I suspect the aeration created by the adjacent vertical step between the center and outer panel of the variable deadrise hull also helps.
Second shot shows the aeration that reduces drag and makes these hulls so soft riding!

If you're talking about that wedge on the bottom, no, SeaCraft's came from the factory like that.
There was a wood block installed between the hull and inner liner where the scuppers are. The brass tubes eventually corrode and start to leak, causing the wood to rot. Here's a couple of shots from the top I took when I repaired mine. I installed a pvc/wood dowel from the bottom to create a plug, filled the hole with thickened epoxy, redrilled the hole and then replaced the brass tube. There is a well about 3" across and 1" deep (2-3" deep in later models with raised decks) in each corner of the cockpit where the scupper tubes are located. You could probably create a more durable version of the same thing using a bronze or Marelon thru-hull fitting. But the wedge on the bottom in front of the outlet is the key to creating a lot of suction!

Bushwack. Thanks for the inspiration!!!
So I am kicking a few ideas around. I still need to determine if I should close off the old scuppers or leave them be. Of course if I close them off it will be a little more work fiberglassing. I like your idea going straight down with drain pipe and not using hose. I just have to find a spot in the cockpit run it thru. I have box stringers whch are about 6" wide so I dont want to drill thru those. |

Well water does always seek level. Have you thought about plumbing extra drains with check valves to the motorwell and adding drains to the transom at the motorwell and leaving your current configuration intact. If the depth of the inside of the motorwell and floor make sense I'd be leaning that direction myself. Then again without standing in your boat in the water and with a tape measurer I could be completely wrong.

Ok guys. Found something today at HD that may work. I will shave the lip down to the taper.
![]() ![]() looking from the center of the boat to the starboard side at the non working horizontal scupper: ![]() Same scupper looking aft. ![]() The new drain will go directly under the existing drain: ![]() The pad at the stern where the new thru hull will go: ![]() |

^ I ended up not using the sink drain kit. The fittings in my last post are schedule 40 PVC. What do you think?

Sandy, if your going to be a serious writer you must play nice for the first two e- books, poems, articles...
![]() LT, I have no problem with the pvc or the bigger diameter; but why not stick with you're initial thought and go straight out the side instead of running tube aft to the old drain. After seeing your viddy and realizing your scuppers drained out the side i realized you simply have too many turns in the plumbing; and if the knuckleheads at sea hunt used sealant, then that much more flow loss can be expected. Assuming you can reach both ends (I know it's a stretch) plug old holes and have real scuppers (like Sandy's previously mentioned ovals) just fore of the old that shoots straight out.
