    Default Ballast pump not working but has power

    Took her out for the maiden voyage and everything is working well except for starboard back ballast pump. 2018 Moomba Mojo. It is getting power and I can here it running. I went ahead and changed the impeller and the old one wasn’t in bad shape. The pump itself has no foreign bodies in it. Where else can I check to trouble shoot why water won’t flow?

    Elementary thing but did you make sure the through hull valve is open?

    Check for any clogs in the hoses.

    Having the same issue but with the front / center ballast. Rear are both filling.

    - are there multiple valves for each ballast?

    - location of the valves on the hill? Boat is on a lift

    There are multiple ball valves but they are usually next to each other. I can reach all of mine with the transmission dog house removed.

    Yes, got it. They were all open. Next order of operation is to check the pump for debris and check or replace the impeller?

    I’ll check the ball valves and the inflow ports for debris.

    Thanks for the ideas. Will report back.

    Ball valves are in correct position. I did the best I could clearing the hoses and found no debri. I won’t be able to test until I hit the water again. I hoping it was just the impeller.
