I just bought a j/30 and am troubleshooting a problem with the bilge hose. I realize it may be aftermarket. Does anyone know where it goes after it ducks under the floor? I can see the (1.5"?) old manual bilge hose under the front port engine mount, then duck under the port quarterberth before somehow going back to to the (broken) manual pump then to the thru-hull in the transom.

Cheers
