No, not uphill at all. If you have a look at some crossed drains such as mine, http://groups.msn.com/baylinerbuccan...o&PhotoID=2193 You'll see that the boat would have to be heeled at 45 degrees or more for the drain hoses to be level. Even with a level hose, the hydraulic pressure of the water level being higher than the through hull would continue to push water out, but slower. The through hull fitting would have to be higher than the scupper for the drain to not work at all, and at that point the cockpit would be self draining (over the side).

That makes sense - interesting photo!

I'm used to wide, low cockpits with drains connected together and led out the back to empty the cockpit quickly You learn something new every day on Sailnet!

It does seem that boats with a narrow transom like mine are more likely to have crossed drains.

I took that pic the day I bought my boat. It was more for a record of what it looked like for reassembly than anything. In the foreground is the empty Volvo saildrive mount. Now I have to mess with my stupid outboard. It's a PITA, and it spoils the lines of the boat.

Yep...crossed wouldn't work on mine...depends on the boat and the location of the through hulls...mine are both below the waterline.

Molded floor for drain

Cam,
Here's a pic of the floor in the cockpit area. With the floor molded like this it's pretty hard to get the right fitting. I still think that the "I" fitting will work if it not to big or tall. Remember I took out a standard lavatory tail pc. so it fits perfect in the lower area which catches the water. The screen plate just layed over it with a couple of screws holding it in place. I really wonder what was installed originally. Any thoughts?

Probably what you took out!
Would a flush head thruhull fitting fit? If not, maybe you could get one turned down a little on a lathe.

I think you just need to find another small plastic piece to go back in there. Anything else is gonna require a bunch of glass work. What is the dimension on the outside of the lip of the lower hole?

Cockpit drain supplier

Hey All,

Update on the search for a replacement cockpit drains for the Irwin. Turns out Marineeast.com has a line of drains that will fit in the recessed area of the molded cockpit floor. The drain fitting has a 2" flange and 1-1/4 dia. body with locknut. the lower body is barbed for a hose.

Opinion!

Help again everyone,

These cockpit drain are something else! What would you guys do? I'll let the pics do the talking for me. And just maybe someone that has a 30' Citation will look and see what's installed on there's. Please Help! Cam: I'm not sure what to do! the plastic thru-hull sticks up alittle to high and the hole is smaller, I just might have to use the lav. tail pc.
