Couple of questions for the Liberty Owners with Macerator Pumps. Mine has a pump mounted on top the black/grey tank that is plumbed to the bottom of the tank by 1 1/2" PVC and then has a garden house hookup under the starboard engine access door. I put a quarter tank of water in and the pump runs, but won't pick it up.

1. Is the pump self priming

2. The dash switch is a momentary rocker switch. I find it hard believe you have to hold the switch down to pump the poo out.

I know this is Jdub's forte, but he's not good with Liberty questions.
