3500 SCR Macerator pump switch

[grant23]

Does anyone know hoe to pump off my waste holding tank when I'm out at sea...things are getting a bit stinky!

Thanks,

There should be instructions on the switch panel. You probably have to open the valve first as well.

nothing on the AC panel...any other suggestions?

The switch plate for mine is in the cockpit just below the throttle. There are 2 switches. No clue how to use them since I boat in fresh water and pump out the waste tank but I do know there are instructions printed on it, just never read them.

The switch plate is quite large so should be easy to find but it will not be on the AC panel. Maybe look in the head.

Is the boat new to you? Are you sure you have a macerator?

Hi grant, phillbo is correct the switches are below the throttle, you need to hold both of them at once and the pump will start but ensure that you have opened the valve found in the engine room. Good luck
