Seacock, installing a new one

Hello, am about to install a Blake seacock for water to a water-on-deck pump.        It`s for flushing anchorchain and guess saltwater is also good for preserving the teak deck when exposed to high UV/temperatures. Well, the fine flush original mounting looks to have been done without any back-plate. And inside of hull, there is the cover of polyester and paint for topcoat.

Would such mounting be advisable for the mounting of a new valve, ie not using the back-plate?  Any advise on this would be appreciated.
