I replaced the water inlet device mounted onto the boat’s hull several times. My general comment is that I found them unreliable so I made my own. I HIGHLY recommend two considerations to anyone who plans to make modifications to accommodate dock water.
First as others have mentioned a pressure reducer is a must unless your boat is plumbed for dock water pressures which can be very high. Next a reverse flow prevention valve should be used for two reasons. The first reason is that the plumbing code around here at least do not want your water pumped back into their system.
The second reason is you are away from the dock using tank water, the pump will pump the water out through your newly installed dock water hose connection. I guess you could install a check valve to prevent that if you want to deal with it.
