Title: 170 Fishbox drain question.
Post by: wingtime on January 23, 2013, 04:32:56 PM
OK guys.  As you may already know I located the source of the water intrusion into the hull of my 170.  I found the hose for the fishbox drain disconnected and laying in the bilge of the boat...  

(http://i80.photobucket.com/albums/j196/wingtime/1987%20Aquasport%20170/DSCN2444.jpg)

The fish box drain fitting seems to be clogged up as you can see in this pic:

(http://i80.photobucket.com/albums/j196/wingtime/1987%20Aquasport%20170/DSCN2454.jpg)

My question is does anyone have a suggestion of cleaning it out?  Or should I just replace the fitting?  Also what is this thing?  Some sort of a sink drain?  Is there a check valve inside that thing?  Should I replace it with a like fitting? Or should I get some sort of a livewell drain or something?

Thanks!

That looks like a barbed fitting (90) that was screwed on to the original straight drain fitting.

Bye Bye..... :idea:

Yup Capt Bob nailed it.  I took a closer look at after work and took some more pics.  I was able to clear the junk out of it.  When I was doing that i could feel what felt like a kink in the barb.... so risking loosing my phone in the bilge I stuck it in there and took a few pics to see what was up...

Here's the drain fitting in the fish box:

And the 90 degree barb that is screwed onto it:

Yup it has a kink in it... looks like someone over tightened the clamps and crushed it.  I tried unscrewing it but that sucker is on there.  This should be fun.

A little PB Blaster penetrating spray should help :thumright: If that doesn't help loosen it, if you have a heat gun and can get it down there, try heating it a little to help loosen it up...Let us know how it turns out :salut:
If it won't come off you can use a stiff wire to pick the gunk out :thumright:

Bruce, that barb if effed up!  Try and get some acetone by the threads of the fitting, if possible, let it soak on that bond joint.  Then stick a screwdriver into the barb, gives you some leverage to spin it...

I was able to get the gunk out of the barb.  I was thinking the same thing Bob.. stick something in the barb for leverage maybe even a 1/2" rod or something like that.  I can only get one hand in there and even then I can't reach very far since my forearm get stuck.  I was hoping I could just change out just the barb and leave the drain fitting.  You think there might be some joint compound or glue on the threads of the 90 degree barb?


Fernando... air saw?  then what?  :shock:

I would think yes. Clearly the PO throw a band aid at it the issue. To me it looks like someone got a pair of pliers or a pair of vice grips on there and chrushed the barb.

Pete that's a nice drain.  Is there a way to plug it if you want?

Bruce, glad you found the problem. Agree, get the old one out, the one Pete has is sweet.

The one I used was like a shower drain  http://www.marineeast.com/a_sch/sch_det ... &pid=02_14 (http://www.marineeast.com/a_sch/sch_det.asp?cid=02&pid=02_14)
 but they do have one with a plug...

Pete, I believe a sink drain is what is in my boat now so your suggestion is spot on.  I don't think it is an issue with your 225 but based on Fernando's input these drains are barely above the water line.  So with a couple of people up front water may come up into the fish box.  Again I haven't had the boat long enough to know if that is the case with the 170 or not but I think it is.  I hope to try and get that thing off of there after work today.

Well after I came home for work tonight I decided to see if I could get the 90 degree elbow fitting off the fish box drain.  I stuck a screw driver into the barb and tried to unscrew it.  Of course the entire drain turned.  There was no real way to hold the drain from tuning. So I introduced the drain to Mr. Die grinder and his buddy carbide bit!  Working from the top of the drain I worked my way around cutting into the drain until I saw the back side of the threads.  Luckily the drain was brass so the carbide bit mad quick work of it.  The I just reached in and snapped off the fitting...  and here is the result:

I went to Worst and of course they didn't have what I needed.  They had the brand Pete suggested but only the short threaded type which wont work.

Well the fishbox drain is fixed.  Turns out finding a 1" 90 degree drain locally with enough threads was tricky.  I ended up having to order this thru hull fitting:

After fishing out the hose and bedding in the drain here is the end result:

Good job :salut:  
Investigating, finally finding the disconnected hose, finding the plugged fitting and then figurimg out a way to get it out, locating and installing the new one and re-connecting the drain hose...  All takes time  :thumleft:

Yeah and almost getting your arm stuck in a 4" pie plate hole is fun!  I also managed to do it without dropping anything in the bilge too!

Ok I took the 170 out today to see if the fish box drain repair stopped the water intrusion into the hull.  I checked the fish box with two people up on the casting deck and there was no water coming up into the box. All looked good. I went back to the ramp pulled the plug..... And there was still water darn it!   There has to be a hole in the rigging trough that I can't see or something.

Nice job on the install bro,check to see if the bilge pump thru hull gets near the water when there is more weight in the stern,I've had that happen to me in an 18 footer,every time the thru hull went under a little water would come in thru the bilge pump.

I replaced the bilge pump thru hull.  It's very high up on the starboard aft side.  If it is under water I'll get a bunch of water in the bilge cause the transom will be underwater!   :mrgreen:

I feel there has to be something going on under that rigging trough cover.  I'll  just have to pop it off and see what is going on under there.  I want to pull those screws and seal them anyways.
