Prefer KISS methods.

Install thru hull & sea cock in conventional method, then install a
nipple and a tee with a plug rather than an elbow.

The hose gets connected to the side connection of tee.

If it plugs, remove pipe plug and rod open, then reclose sea cock and
replace plug with out any undue haste.
