Ray:
Jabsco 29090. Same as the old one that lasted for the 11 years of our
ownership. It was pretty new when we bought the boat.
You will have to replace the joker valve and the flapper valve every
year or so if you don't flush a slug of fresh water
as you leave the boat each time. Uric acid malforms the rubber in the
the valves and crystalizes on them.
The main reason that I chose to replace the head was that the plastic
wore out that receives the screws holding
the plates that contain these values. I had the choice of new head and
smiles from the ladies, or taking the old one
home to the shop, hope to be able to fix it, then spending another
potential sailing day screwing around with reinstalling
it.
I have the old head on the work bench and see that I could have
drilled out the plastic and glued in drywall
screw anchors to refurbish the failed screw-holding plastic. $200 well
spent. We are ready to join the
chaos of the Americas cup spectator fleet this weekend.
Anyone want the old head? It has a new pumping unit.
