Hi all,

Where do the port and starboard bilge drains lead? I have attached pictures for reference (excuse the dirty bilge, ink, tar and all sorts of crap in there. Full restore coming soon).

Long story short, the batteries in my 1984 Tournament 190 were re-positioned, revealing a soft spot under the port jump seat. Cut through to find good wood but wanted to fill the gap with a bit of foam. Filled to satisfaction, but noticed it took more foam than expected. Next day, noticed hard foam in the bilge.

I'm guessing they are stringer/ bulkhead drains, but it would be useful to know the source before I go tearing into the floor again. I would love to block the other holes and flood the bilge to eat away the foam, but it's far too set for acetone to have an effect on it. Looks like I'll be redoing part of the floor.

Any replies appreciated. Thanks.
 
Those holes - commonly referred to as limber holes (although they should really be an actual "tube" to avoid stringer contamination) - drain any water that collects on the outboard side of the stringers down to the bilge.

Many thanks Dennis!

Any idea how these are laid out on the Tourney 190? I need to figure out my plan of attack in case the auger doesn't work to clear the blockage. I agree, it should be a PVC tube or something.

Thanks again.
 
On my boat, and I can't imagine it being any different on your boat since (1) the general construction between our two boats should be the same and (2) it's the most common/logical way for this to be done on ANY boat, the limber hole is simply a passageway from the outboard side of the stringer to the inboard side. Essentially, it's just a simple hole.

Is it closed cell or open cell foam? Augering it out sounds like a good plan. You may want to use a bent coat hanger (hockey stick) to further get rid of some of the foam on the outboard side of the stringer. My worry, though, is water could end up being trapped behind the foam and not allowed to drain out as it will be difficult to know exactly where the foam expanded to. Aside from the problems that water can create (the weight of the water, too), there could be freeze damage. I would just make sure to get rid of any foam you can from any/all directions that you can get at it to try and make a clear path for water to drain through.

In the back corner of the "shelf" (where batteries sit under the corner seats), there is a drain hole? You either need to make sure there is a good "no brainer" pathway for water from there to the limber hole, or possibly seal up that drain hole.
 
Got it. Many thanks for this. Strange that there isn't a PVC tunnel of some sort.

Closed.

That's my concern as well. Somewhere the foam took the path of least resistance and went for the limber holes. I live in a warm climate so freezing is not an issue, but wet foam is always a concern.

No drain hole there.


Thanks again. Any other replies appreciated.
 
Just an update on this.

Cut open the floor, figured out how the limber hole got blocked, cleared the blockage, patched the floor. Learned a bit more about the stringer layout on the 192 as well. Will post pics later in the week for anyone who has the same issue.
