I need a thingamygig

[Trimix]

I don't know what its called, but mine has a crack in it and could do with replacing it (queue for wise cracks)

The rear splash well drains out through the transom and to stop water coming back up this drain on the outside there is a transparent valve with a ping pong ball in it. (high tech)

That's the thingamygig that has a crack in it. So in order to Google a replacement can someone tell me what its actually called

Cheers.

Actually, I've Googled it now I know what its called and found a few. But they all seem to be in the States.

Hi Trimix..
I am not a fan of those, my Gemini came with one as standard,
but what I found is they are susceptible to foreign objects wedging them open.
I got a concerned call from another boat owner a few years ago
when on a mooring in Cornwall, as my rib had water
lapping over the transom it was sitting that low and all because
the ping pong bailer had been forced open by a small piece of label
from a 2 stroke oil bottle, that must have been floating around.
I took the bailer out, replaced it with a screw in bung, and fitted a second bilge pump!

Mmmm, I good point.

I will have a look when I get home, but my boat has a different arrangement to most.

Its got two drain holes that empty the floor into the bilge, where there are two pumps (permanently wired in)

Then there is the extra drain hole from the boat that empties outside the transom - this is where this scupper is fitted.

So I suppose if it failed, the boat still has two escape routes via the bilge for this to be emptied.

The floor is above the water line I think so this is only a scupper for when / if the waves come over the side.

But I need to have a think and look when I get home.

Aye, any alleged non return valve to empty your bilge will inevitably be held open by dirt / sand / whatever is carried aft by the water.

I had the same story with an OMC Express which uses (used ) a rubber disc arrangement with equal unreliability!

I would go bung / elephant trunk., then you aren't relying on a battery.
