I have a '97 SeaRay 270 DA (Sundancer) and have exactly the same problem as above (or below). I think that what has been suggested is accurate without any doubt. I have a couple of questions and hope thats SOMEONE!!! knows the answers as it's causing me lots and lots of grief.

Ok. 1. Assuming that the sump pump/bilge wiring needs replacing and that the sump pump itself has corroded wiring, how can access be made easily into the very tight cavity in which it is located. I would like ideally to remove the stair well from under which it resides but cannot work out how to do it??? Does anyone have any experience or ideas? I have contacted my local SeaRay dealer and they do not even have a manual for the deconstruction of the boats!!!!

2. Does anyone know for sure if the the other input into the sump (knowing that one of them is def. teh shower drain) is the air cond unit? I was guessing that it maybe the water tank overflow run off, but this is just a guess. I would love to know for sure. IF it is the ac, then how does it get water into it if I dont ever use the air con????

ok lastly,3. I also need a new boarding ladder and am finding it extremely difficult to locate an after market one. Not keen on paying A$900 for a new OEM ladder.

Any help would be greatly appreciated.

I did not. On my Sundancer, which is admittedly larger than his 250 but is
of the same vintage, there is absolutely no way for rainwater to enter the
forward bilge area directly. There is simply no way outside water has any
direct access whatsoever to that area, which is exactly why Sea Ray did not
install a bilge pump in the compartment. While it is possible that his 250
might be different than my 290, I highly doubt it. It is entirely possible
that there is a drain source that could route outside drainage water into
the sump. What my post suggests is that the water that is in the forward
bilge area did not enter the bilge directly, but rather through the
overflowing sump. This may or may not have anything whatsoever to do with
recent rains. My post was intended to suggest that the owner reverse his
thinking. He was wondering why the water in the bilge compartment was not
removed by the sump, and my post was intended to alert him that the sump
itself is very likely what put the water there in the first place. Perhaps
you missed the part where I mentioned that I've had it happen twice on my
boat.

In other words, I offered a potential diagnosis and solution based on
personal experience that required just a little bit of thinking outside the
box, a place your mind refused to be led, resulting in your comment which
offered a grand total of nothing.[/quote]
