Bill, Is the "Skipper" model the larger all bronze head? If so that is what I have on Calypso. To reduce the galling/sticking of the main pump I have been rinsing fresh water through after a day/trip then adding a treatment/lube compatible with our holding tank treatment.
Some holding tank products advise not to use oils that will create a layer on top of the holding tank's contents, in particular the KO and CP products created by Peggie Hall. I have rebuilt Calypso's bronze head several times to renew the pump leathers and repair electrolysis type damage to parts that always sit in salt water. Calypso's next head may be a VacuFlush or something of a newer design than the old Wilcox / Thetford products.

We as sailors are always trying to find the generic version of the marine grade that we know is ripping us off. I have the Skipper, and noticed that the pump has been feeling like it is galling, and was worried I may have compromised the rubber in the pump. I found Thetford head oil can be found in RV stores, (Cheaper) and I bought some and have been using that instead. It definitely feels like it is more lubricated with that stuff, but the effects don't last long. Bill Coleman C&C 39 [animated_favicon1]
