For some reason whenever we try to turn on the pump it doesnt fill imediatly. Its make a low hum and doesnt pump. We waited a couple of minutes and finnally it would start. <BR> <BR>Does anyone have this same problem and is it normal? If not what would be a reasonable solution? <BR> <BR>We have a gravity I ballast system. <BR> <BR>Thanks

are you driving the boat then filling

No usually not. We only dorove it once and still same thing.

my moomba does the same thing, I am sure it is just like priming the system then it starts, it is working though

moomba uses a scoop grate drive the boat to 20mph and then turn on the ballast it will fill fast .

normal on thsoe style pumps, my supra does the same thing.

Thanks for the help guys. Very much appreciated.
