'06 210 SANTE Pumps breakers popping

[210 Hopeful]

When I use the belly (not port of starboard) to pump out tank, the fuse pops. If you use it to fill the tank, no problems. How do I fix this? Any ideas? I checked to see if the pump was warm, no that. Instantly I thought to post on PN.

Probably a short on the hot for reverse flow. Are these ballast puppies or aerators?

I will have to check on that. I just bought the boat a few months ago.

Change the impellers. They have gotten hard and will cause high amp draw and trip the fuse. Even if they work in one direction and it trips in the other direction, its the impeller. I had similar problems on my 06 210. Changed all three impellers with the green ones from Nautique parts and it hasn't skipped a beat since.
