Aahhh the holy grail... Seriously, I would like to do this as well.
A fellow on the liveaboard list suggested contacting all the Spectra
dealers in the US and getting a price for a replacement. I recall the
price for the Clark pump alone was ~$3K.

The class of device is generally known as a hydraulic intensifier, but
all the commercial ones that I know of are suited for air or hydraulic
oil, not seawater
