Default Sea Ray Sundancer 250 DA bilge queation

Thanks for your suggestions. All are relavent and I'll be following-up over
the week-end. I am familiar with the sump "box", under the cabin stairs.
Stay tuned for an update Sunday night. Marty

Thanking those who responded. The fact about isolated bilges seems
clarified, and this is important for me to figure what is going on. Also,
I gather the contained shower sump keeps the soapy runoff out of the
bilge.


IF it is, in fact, operational, it is designed to collect shower drainage
*and other drainage that is routed to the sump* (extremely important
concept) and therefore keep it out of the forward bilge compartment. If
it has gone non-functional, it will, in fact, overflow and fill the
compartment with all drainage sources plumbed to the sump. You must
inspect the sump. You will likely see more than one inlet hose going into
the sump, and only one outlet hose. They should all be labeled. Since
you admit that you haven't used the shower in quite some time, you
absolutely need to test the sump pump to see if it is operational. Run
some water through the shower drain and see if the pump is turned on via
the internal float switch being floated by the shower runoff. If it does
not turn on, which I believe is a distinct possibility, you have found
your problem. If the sump is operational, then you know you have to look
elsewhere for the water source.

By design, there is no way for water to enter the forward compartment
directly. That's why there's no pump in the compartment other than the
one in the sump. That doesn't mean that something hasn't gone wrong
somewhere, and is allowing water to enter the compartment, but it's not as
likely as water entering the sump by design, but the sump not pumping the
water overboard and therefore allowing it to overflow into the
compartment. Here's some possible scenarios:

1. Rain water is leaking into the head area (shower), possibly through an
open or defective portlight, and is draining by design into a
non-functional sump, then overflowing into the compartment.

2. Rain water is draining by design from one of the other plumbed drain
sources into a non-functional sump, then overflowing into the compartment.

3. One of the inlet hoses to the sump has come off the sump or is
otherwise leaking its contents into the compartment before it gets to the
sump.

4. Rain water is leaking into the cabin, soaking the cabin floor, then
filling the compartment (reverse thinking from your assumption that the
water is first going into the compartment and then overflowing onto the
cabin floor).

5. Rain water is indeed leaking directly into the forward bilge
compartment due to some defect that has appeared somewhere in the boat,
and then overflowing onto the cabin floor.

Understand this. These self contained pumps are cheaply constructed and
very much prone to failure. Your boat is a 1998 model. If your sump
hasn't failed, it's past due. Mine is a 1999 model, and the wiring in the
sump has failed twice. And if the pump in the sump is non-functional, any
water entering the sump WILL overflow into the compartment, and then
overflow onto the cabin floor. I've had it happen twice. The first step
in your diagnosis should be to determine if the sump pump is functional.
It's an extremely easy thing to test. Takes two minutes by running water
into the sump from the shower drain and waiting for the pump to activate.
Also, the sump is designed to be serviced by the owner. There is a filter
of sorts inside the sump that collects hair and soap scum, and needs to be
cleaned periodically to keep water flowing correctly into the sump.

If the sump is operational, then your best approach would be to have
someone stand on the foredeck (and just about everywhere else) with a
water hose, spraying down the boat with as much water volume as can be
mustered, while you are in the cabin looking for leaks. The leak could
manifest itself directly in the forward bilge compartment, but allow for
other possibilites. The water could be taking a circuitous route to the
compartment.
