i have a 2000 moomba mobius v and i'm not sure if the bilge pump is working properly. don't really ever need to use the bp because i always pull the boat out of the water and let drain on the ramp, but heading on a trip where the boat will sit in the water for a few days and need a bp. anyway, when i flip the switch the accessory light comes on but the bilge pump doesn't make any noise. not sure if it will only come on when water is actually in the bilge or if the pump is bad.
