scupper change from floor to transom
 

I have a 76 23 cc with large floatation bracket and 225 yami 4. boat drains fine and does well until you have a coulple of big guys in back. Can i get some feedback from the guys who have gone through the transom without raising floor. ie how well it works, how hard it was etc. It looks like it will be hard to get in there but it looks doable without cutting floor. I have already recored some problem spots in floor . thanks

Interested to hear people's experience with this as well. I have a similar project in mind for my 23.

c'mon can't believe nobody has any feedback on this , how bout it folks help a brother out.

Lets see some pics of the boat, and the existing water line. Each boat is a little difrent, its hard to tell without seeing it.
Whats a 'large' floatation bracket?
Whats your motor weigh?
Your stringer boxes are going to prevent you from going in from the bilge to attach hoses. Whats your plan for those?

Pics would help.

Chances are you want see that big of a difference. Maybe add some ping pongs to the transom if you were togo that route would help alittle.
Your floor really needs to be raised if it is still original.

Floor Scuppers
 

23' s don't need floor raising. My Floor scuppers ran thru the transon even before my barcket install without issues. I raised them about 1" with this current setup.


1.) Fill / Glass in old Floor Drain
2.) Glass in fiberglass tubing
3.) Gemlux Flapper type S/S drain thru the transom with 5200
4.) Tie in drain tube & Scupper with ridgid bilge hose & S/S clamps

i prob have the heaviest motor of anyone on a 23-a 250 verado (chipped to a 275 now). About 650 lbs. The scuppers on my rig were done by prior owner exactly as Chuck says to the letter. It is only wet if 2 guys are in the back corner, and one of the guys is over 250 pounds. Case in point, me at 175ish with an equal sized fellow this weekend,full gas,50lbs ice,gear, we had dry feet. AT rest. Both in the corner, and we tested that on purpose actually :). We were talking about it in fact.

If the floor was raised a little it would be perfect, but unless i need to do the floor its not gonna happen for a few more years at least. Even then I may keep the floor at its current height, since I may not totally remove the floor to redo.

At rest the boat is self bailing right now, and its an Armstrong bracket for a 25" motor. I think the hermcos prob have a little more float but thats conjecture on my part. If i had a dream bracket it would be the hermco, with more floatation going outward than exist today. You dont need a dive ladder to get back on the brackets, and only need room for tabs.

I have the rubber flaps, they do let some water in if my fishing bud is north of 250 and we are both in corner. I prefer the flaps as i think in a pinch they would evacuate more water that than the ping pong ball types, but thats preference. IMO less to go wrong with the flaps, i dont want to think about my scuppers and ping pong balls if a wave comes over, just want them to work. HOwever if raising the floor say another inch or 2, Id go with real big scuppers like the rectangle style with flaps. Again overkill, but i do know someone who took a rogue wave offshore in their classic 23 with scuppers out the back, and bigger is better for scuppers.

Yeah they all will mostly selfbail at rest sittin in a slick creek.
Every older Seacraft I have been on, twins/singles, motor on transom/motor on bracket, floor raised/not raised, etc.... have always had wet floors at some point.
My 83' 23ft I redid, I raised the floor 4.5 inches, moved the gas tank forward, had a bracket, 2 stroke yammy 225hp would still have water in the floor on occasions. Most of my fishing and rigging is done at the back of the boat so there was always 2-3 people in the back and 50gals live well and fishing in at least 2-3 swell with a wind chop. Usually there was water in the boat. (Harkers Island Nikes, Wanchese Slippers what ever you want to call them are a must (White Boots)).. Defianltly does not scare me away from the boats. Shoot about any boat I have been on under 25' has a draining problem when you are in seas with the crew at the back. Only the 30ft's and up I have been on self bail really good. (Contender,Yellowfin,HydraSprot).

IMO I would never own a older 23' that has not had the floor raised. From my past experiences the Seacrafts I have been on without the floor being raised had wet floors all day.

Shoot even my 77' MA I raised the floor 5". It selfbails good but there have been times where I said damn another inch or two be nice. Refering to the floor that is :-0

Thanks for those pics. Very helpful. That is exactly what I will be doing this offseason.

Quick question, when your boat is at rest are those scuppers above the waterline?

RC

yes

thanks a lot guys , gonna try and post a pic.

thought some of you might be interested in embroid work

Thats purty. How many inches of the back of the boat are in the water. At the rear corner from top of water to chine?

Very nice Paul!!! I'm betting the Dusky in the background "is green with envy" to even be in the same marina as your SeaCraft. Sorry....I couldn't help it. ;)

seacraft 84, it is about 2 1/2 " without the transom livewell full.

I'm guessing that the "T" is to drain the boxes in the stern?

Transon Boxes & Rod Holders = NO water in the bilge

I have a 2001 SeaCraft20. I am thinking about adding scuppers above the waterline and above the floor so that water would run out if I got alot of water in the boat. The scuppers I have are self bailing but water does not leave very fast unless one is going forward, which may be tough to do if the boat was in the situation where there was alot of water in the boat. A consideration would be that if there was alot of water in the boat, would the scuppers then be under water and rendered useless? Any thoughts? These would really be emergency scuppers. Thanks for your input.

scuppers
 

I am thinking of adding above the waterline scuppers to get rid of water should I ever have several inches in the boat.With the scuppers I have( 2001SeaCraft20) the boat must be moving forward to get the water out with any kind of speed. AM I better off w a pump on the floor? I don't think it is as straight forward on the 20 as it is with the 23.

So you want to add scuppers above the deck to drain faster when there is allot of water, sort of like an overflow. :confused: If you're not draining fast enough and you think it might me dangerous, enlarge your current scuppers to let more water through. The bigger the hole more water drains out.

Capt Chuck, where do you get the 1" fiberglass tubing?

If I remember, it was Widfire Marine here in Stuart. It might have been an old extendo stick.

Check out McMaster Carr

We have had zero issues glassing to PVC but I like the suggestion of using pieces from a wiggle stick.

I've used these a lot for scupper tubes too. Also from McMaster Carr.
Made with straight up polyester resin. A little stronger than the garolite and rated for outdoor use.

Thanks Fellas! Do you guys make the drain from the deck to the transom pretty straight or slight angle downward?

My boat is just about ready for the season and i'm thinking of tackling this beforehand.

Right now I keep the scupper drains plugged from the deck and can easily remove but looking to convert to "maintenance free"

I prefer marine exhaust hose (black stuff) to the white hose....heat it up with a heat gun and can bend it a bit as well. i use it for everything > white hose...but prob overkill. I also believe in 2 stainless clamps each end, orientated so each nut is on opposite sides. again overkill. Use some soap to help get hose onto the stainless fittings....

tip - I get clogs up on my limber holes as the 4 stringers are tabbed to transom....mainly the outermost section, something to eyeball here and there on a trip. these are the little weep holes to drain water into bilge go thru each stronger. if talking about water evacuation..
