Main Floor Drains
 

Where should the floor drain to ? My V-20 just dumps to the shelvs that the oil tank, and the battery sit on.......

Re: Main Floor Drains
 

Depending on the year they either drained into the bildge or they drained via a plastic hose to thru hulls mounted on the sides just above the water line.

Re: Main Floor Drains
 

Its a 87, and i guess i need to run a hose to the bildge from the fitting, right now it just drains on the shelf and it has a hole in it that goes somewhere

Re: Main Floor Drains
 

i called it " Its " i havent named er yet

Re: Main Floor Drains
 

For a 1987, you need through fittings.

Re: Main Floor Drains
 

Here is a picture of my floor drain. It drains from the deck and out the side. Does your V have hull fittings ?
Find out first before you getter her wet.

Re: Main Floor Drains
 

H, I think that's exactly where they were made to drain. The cockpit floor fittings (in both corners) of my '86 ... dump right onto the battery shelf as well. Some here say - that their pre-'88 models drain outside the hull. I have been meaning to take a yardstick and level .... and try and determine whether my floor has any positive height above the outside waterline. If it does, then I could add a hose to the floor fittings and plumb them outside the hull. But I dont think that is going to be the case. If it were, I would imagine Wellcraft would have done it from the factory. The 1988 and later models - had the floor raised a few inches to accomodate draining overboard.

Re: Main Floor Drains
 

I really don't understand that at all, mine is an 85. Every boat I looked at ( a lot ) had thru hulls that the scuppers drained to. I know earlier boats, not sure when it started had scuppers that drained into the bildge area.
???

Re: Main Floor Drains
 

Willy, how well do your floor drains work ? Do you have issues with outside water flowing back in ? Or is there sufficient height differential to prevent that ? Just wondering.

Re: Main Floor Drains
 

As far as I know, I dont have a raised floor with the recessed floor drains. Your V for the year should have scuppers. If they dont, they may have been glassed over for some reason. The scuppers are right at the waterline. But I installed a deck drain with a ball in it to stop water from coming in. Also, if you look at my drain that i posted, I have a ....cant remember what its called now, but there is a rubber flapper inside the valve that stops water from coming in, but lets water out. I picked them up at West Marine. You really need to post pics. of your drain set up so we can get a better understanding as to what you got.

Re: Main Floor Drains
 

They do well on my boat, if you check my gallery you'll see they sit about two inches above the water line. Even so if you got guys standing in the back and your rocking they let water in and then it flows back out. They all do. I've been on big sport fishers that do. You can add a one way drain like I think Hammer did and that should work but they will not be as free flowing and you will have to make sure nothing clogs it up inside.
What I do is before I launch I put in three plugs and they all sit together in the transom compartment. One is the standard screw in garber plug of bronze, the other two are the rubber and metal type garber plugs, the kind that you put in the hole and flip down the toggle to snug it. Those two go in the scupper holes, perfect fit. If I get into any snotty stuff I just pull them right out (two fingers) or if I am washing fish crap off the deck. Etc. If it is just normal fishing and playing, even in a heavy chop I never get any water in the boat so they just stay in.
If I got any water from super models climbing in and out from swimming tubing etc I just pull one of the plugs when I start moving forward and it all runs out in two seconds.

Re: Main Floor Drains
 

I like the one way drain for piece of mind, but do agree with Willy about clogging. I have a screen for large objects, but I track in alot of sand to the boat whenever I climb in and out. Gotta hose out the drains really good to make sure I get all the sand out.

Re: Main Floor Drains
 

Mine's an 87 and drains out the sides as well. It wouldn;t happen to be an I/O, would it. They went to the raised deck about 80 or so, maybe 79.

Good thinking there AIR. He need to post some pics. and we can go from there. ;D

Re: Main Floor Drains
 

My hunch is that the I/O's may have drained into the bildge longer into the prodection run? It's a stretch of a guess, but the I/O's weighed a couple hundred pounds more and had full transom, so maybe wellcraft just let em drain to the bilge?

Re: Main Floor Drains
 

Well sorry I am late on this but my 84' is an I/O and she also drains into the bilge. the through holes in the back of the deck go right onto the battery shelf in the bilge area.

I have also thought numerous times of trying to plumb them through the side of hull. But not sure of the deck vs. water line? Anyone ever try this? just curious? Every time it rains when my boat is at the marina, she fills up to the bilge pump level and sits real low in the water :-/

Re: Main Floor Drains
 

That was my hunch. I can think of two reasons. The thought with full transom that you would be alright, or that with 350 Chebby she might sit a just a bit lower than with a 380lb outboard?

Those are my thoughts on the why's?

Re: Main Floor Drains
 

Air,

So do you think i could go to through holes with my original 470 Mercruiser? Or would the deck be below the water line?

Re: Main Floor Drains
 

My 1991 I/O drains overbd, the ovrbd holes are about 2-3" below deck level

Re: Main Floor Drains
 

garagenc

i would love to see a pic if you can

thanks

Re: Main Floor Drains
 

I'll check to see if I can find the camera and take one now. check back in a little.

Re: Main Floor Drains
 

THANK YOU SIR 8)

Re: Main Floor Drains
 

Somewhere about 1988 they raised the deck maybe 2", at the expense of cockpit depth. I'm just guessing here, but I'd bet that pre 88 I/O's drain to the bilge and 88 and later dran overboard. I'm sure Wellcraft had a good reason.

I'm not sure if there is a waterline difference between Outboard and I/O boat or not. Maybe Wellcraft just though that with a full transon it would be OK? Bilge pump can handle rain water, but with a notched transom they wanted the floor to drain better? I'm reaching here....

Re: Main Floor Drains
 

Here you go I took 2 of the outside (port & stbd) and one from the inside, the inside is 2-3" below my dk level, the rod box is remvd and the image is shown below the main dk lvl.

ps the chrome outlet is the dk drn and of course the blue line is the water line, but I never get water back into the boat unless I have a 350lb+ guy in there standing right at the drain. Also the plastic overbd drn and is 2-3" abv dk level. The inside pic shows the shoulder support for the dk so that should give you a idea of the placement.

let me know if I can help further.

Re: Main Floor Drains
 

so is it the white one? what is the stainless one? live well feed?

is there any type of anit-reverse flow device in the drain? what i mean is can water from outside come into the bilge?

Re: Main Floor Drains
 

I modified the pics to help describe it further
see if that helps

Re: Main Floor Drains
 

i only see one hole on the inside pic, where is the other?

Re: Main Floor Drains
 

I have a 75 and all goes to the bilge, I have wanted to try to make a self bailer, but I would need to see more pictures! ;D
Were are your drains on the deck? and how do they stop the water from going down threw the engine cover?

Thanks!

Re: Main Floor Drains
 

Whats a "dk drn"?

Re: Main Floor Drains
 

my 81 outboard drains from the corners of the cockpit to the splash well, just 3/4 hose plumbing it. I guess its self bailing in theory, but two 3/4 outlets are nowhere near enough. I plan to open up the cockpit drains to at least 1"(maybe even bigger) ID, and drain them over board rather than to the splashwell. Do the outlet drains work better on the side of the boat or the back?

Re: Main Floor Drains
 

dk drn deck drain,

The second outlet you see (plastic) is for my bilge pump on 1 side and on other side it's for my aerator.

I have clips that screw in that block off the eng cvr, my drains are located about 1-2" fwd of the aft bhd.

I can take pics of the eng cvr block off's and the deck drain ("dk drn") if anyone would like, but it will have to be tomorrow, I have to leave for work in the next 20 minutes.

Re: Main Floor Drains
 

Thanks garage, I'm not the sharpest.

Spare, I think the drains are on the side to allow them to be higher in relation to the waterline than if they were out the back, the transom being the lowest part of the boat. *If you run them out the back you would have to be sure to put flappers on them, otherwise water will shoot in when you back up.

Re: Main Floor Drains
 

That black hose is on the edge of popping off. Be careful.
