I replaced my Rule 700 drain pumps on the rear bags because both quit sometime last season (one wasn't working when I bought the boat and the other quit towards the end of the season). I replaced them with Tsunami T800's (mounted in the stock positions), but I've been having trouble getting them primed, or that's my assumption. When the bags are full (750's) and I kick the drain pumps on, I can hear them, but barely a trickle comes out. What I do is turn them to FILL, and wait until water starts coming out the drain tube, then kick them back to EMPTY and then they work just fine. With the Rule pumps I never had this issue and the center bag Rule drain pump continues to work just fine. It's a pain because sometimes I fill the bags partially, but then they won't drain at all.
