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.

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.

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.

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
