Default slush in boat

I just bought a maxum 2300crs and in the boat under the engine is a lot of black slush.

if i pump it away with bilge pump it fills again but it doesnt overflow.

anyone any idea where it might come from judging the picture?

That's a very dirty bilge.

Is the boat sitting in the water and does it refill just sitting still? or does it only happen when the engine is running. Many sources of leaks.

Yeah, more information needed. If that boat is in the water I'd have it pulled and all the bellows inspected. That is a LOT of water in your bilge.

What is all that gunk on the other side of the stringer?

It probably doesn't overflow because at about that depth you'll hit the level switch on your bilge pump and it's pumping all that oily water over the side.

Mine gets filled by rain water from a leaking rub rail, but there are lots of potential sources.

Like Phillbo said, make sure it's not the bellows as if they get worse and your boat lives in the water, you could overwhelm the bilge pump and sink the boat.

Suggest getting a wet/dry shop vac, vacuuming it out completely and then watching for a while.
