I have a ModVP type tunnel, and because wakeboard boats, it's constantly taking on water.  My problem is that the outer sponsons fill up and I've got no way to empty them except with my kids squirt gun or pulling the plugs.  I can't put a bilge pump in each sponson because the gas tanks go all the way to the transom and fill up all but about an inch of the sponson. 

J-drains would work, but I don't like they stick open if a piece of debris gets in 'em, so that's off the table.

I was thinking of setting up kind a piece of tube hanging off the back of the boat just touching the water in hopes that it would create enough vacuum to suck the water out, but I have no idea if that would work.

a self priming pump with accomodations for a hose on the suction side would work, but I've got no idea where to start looking for those, as most are listed for specific applications, rather than listed by how they work. 

any ideas?  I have to pump it either out of the boat or just into the center keel, where I have a bilge pump.  Also trying to keep it under a million dollars.

Pat, just steal one of those ballast pumps out of a rollbar boat, they certainly don't need it. If you take a long hose you could pump the water
out of your boat into whoever is being the dick for the day. Ha ha ha !!!
Just don't put it in ours, i've got
enough problems already .
Hope that helps

No J-drains, I don't trust 'em.

Had a stupid idea today...maybe a good one, we shall see.

I was checking out my blue-point vacuum that runs on compressed air.
I'm gonna try a v-drive style water pickup and make a Venturi pump, whenever the boat is on plane, it should suck water outta the sides.  With my luck, I'll probably hook it up backwards and sink the POS

Stupid compressor still cycles every 10 seconds, but witch's tits ain't got shit on the temp inside the cab.

I'll play with some different entry nozzles to see what works.

Got any pics of the garden hose rig?
