Another scupper post

thehermit · #1 10-11-2006, 11:24 AM

OK I have searched many a post on the "in floor scuppers" on the 20' CC. My question is: Has anyone ever tried switching the 1969 and 1970 scuppers that drain through the deck and then out the transom to the 1971 and later that version that drain through the deck and out the bottom? I am re-doing the transom on a 1970 and the scuppers drain pretty much below the waterline. Some of the other posts on the 1970 boats mention as soon as you get in put the plugs in or else-water on deck. I wonder is this the same on the scuppers that drain out the bottom?? (1971 and later) I am not planning on rasing the deck. Just wondering if there is any benefit at all to re-routing the thru hulls to the bottom. Curently the thru hulls and the deck drains are connected via a (original) rubber hose. THANKS . THE HERMIT

The problem with the water-on-deck in the 20' isn't related to where the scuppers are located, it's due to the deck being too low.

I had through-the-floor scuppers in my 20' and through the transom scuppers in my 18'. Both boats had wet feet syndrome prior to raising the floor. Either boat was fine just sitting in the slip by itself but as soon as humans were introduced into the equation, the water came right on in.

One thing you can try with those scuppers out the transom is the ping-pong ball type covers. Several companies make them (Rabud, etc) and while not perfect, they do help some.

Having had both styles of drain (scuppers), I would never change from the out-the-transom style in favor of those through the floor straight-down scuppers.

Ikan,
Did you ever consider eliminating the deck drain and building a scupper to drain through the area of the jump seats and out the transom. By my estimation this may rasie the scupper outlet at the transom by as much as 2" but you would definately be giving up the good bailing of the deckdrains while on the mooring. I think others have tried this as well (Goerge's 20' in the Gallery).

No, I was well aware that my floor/deck was right at sea level, so in my situation, no locational change of the scuppers was going to change the fundamental problem. Once my floor was raised 2.5", the problem was solved. I no longer have a splash well or any plugs for scuppers, merely two 2" holes right out through the transom.

If you are having water intrusion issues and yet have no plans to raise the deck, I would suggest Rabud ball scuppers in addition to plugs for the drains in the cockpit.

I may very well misunderstand what your are proposing but I would think that if the floor is at sea level, physics dictates that you are going to have water issues regardless of how high above water the outlets (scuppers) are. Any spray/rain that gets in will still have to get out and I think the outlet will need to be the lowest part of the equation or the water will merely back up inside the tube.

My scuppers as they are now (notice how the floor/deck in the first photo actually slopes slightly down to the center, this effectively chanels any water/spray right into those drains) :

I went with TH flaper succupers out the transom on23 they work good

So basically it dosnt matter the setup if the original floor is left alone. OK so you keep the bronze thru hull and mount the ping pong ball scupps over the top somehow?

The ping-pong ball scuppers aren't perfect, but they will likely help you out quite a bit. Try to keep the leaves out of them and they do pretty good. Some brands, such as Flow-Max ( http://www.thmarine.com/product.cfm?PRID=55 ) have a single set-screw that allow you to bayonet the outer part off and let debris out very easily, this is a very nice feature to have (it's not on the Rabud's).

I fully realize that raising the floor is more involved than many want to contend with. That being the case, get some decent ping-pong scupper covers and some plugs for the cockpit area and be careful in rough conditions - if you take on serious water, get that thing on plane as soon as you can.

Man! Every time I see those pictures I realize that boat is just TITS! Nice work. I want to come fish it!

When I redid my transom in 99 I was not aware of this site. I believe my system was factory. Floor drains in rear corners, dropped 1.5 inches or so, turned 90 degrees then went under the storage compartment and livewell, and out the transom. But it had all been replaced with (rigid, H-D type PVC plumbing Sh!t) with threaded fittings outboard and capped. You've seen the crap. Looks like the outside of an Igloo cooler. The glass guy I used convinced me to simply drain those originals directly into the bilge and pump it from there. Do I now have the true defination of a Sinkcraft? After reading Otto's experience of last weekend, I need "QuadCrash" pumps. Standing by with little confidence. Part II. Nice boat Mark!

Take 95-South after March 1 and we'll fish it! a handful of members have visited and you are welcome to do likewise/

Vezo, I still have that original setup you talk about. I think I'd rather have wet feet than pump into the bilge. As i understand it if you are running she will bail nicely. One friend installed a clamshell over his thru floor scuppers to stop water from shooting up through as he comes down on waves. I think i will stick with the original layout.
