Looking for an electric pump for my bilge.

I'm having some trouble finding a smallish pump that won't foul with debris.- 12v ideally
- no reason for a float, I'll operate it with a switch
- must input by hose, not mesh/grill

- must be able to run dry and self-prime
- fittings must be large - 1/2" so it won't get clogged with debris
- low flow - I'm not trying to drain a lake here
- not one of those huge 1/2HP things, I want something more portable - like the size of a shoe

I'll have a few feet of hose on input and output, so I can put the ends where I need them.

Apparently, diaphragm pumps are better than displacement or centrifugal pumps for debris-filled water

I've looked through hardware stores and Amazon but very little joy. I'm going to start looking at aquarium stores.

Just wondered if anyone had any other suggestions.
