I had my 1992 Hunter 30 surveyed (pre-purchase) back in mid-July. It has a Jabsco head (original???) plus the Jabsco electric flush conversion. The surveyor noted that the pump was a bit sluggish and indicated that it is time to replace the impellers. He advised that I needed to do that soon, because continuing to use it could damage the pump. I've owned the boat for about three weeks now, and I haven't used the head at all. Friday I had someone on the boat doing some other work. He was looking at some of the wiring and was trying to trace down the wiring for the electric head. He asked me to turn the head on. I turned the knob, but nothing happened. We played with it for a while longer, and it appears that the pump is not working at all now. This guy recommended a new electric conversion kit.So, I've been looking. The new electric kit is $299. I know the Raritan PHII that Peggie recommends is only about $275. So I'm wondering if I would be better off with an all new manual head or if I should have an older head with a new electric conversion kit. BUT, I measured today to see if the Raritan head would fit, and the height is a problem. The book says the Raritan is 14 1/2" tall. I only have 13 1/8 inches between the floor and the bottom of the fold down shower seat.So I need other options . . . Any words of advice?
