[C320-list] Need advice--raw water anti-siphon valve

[Dave Ouimette]

I have a 1995 C320 with a Perkins engine. At some point in the past the raw water anti-siphon valve was removed. From the Catalina owner's manual it appears the valve was installed by the factory in the engine compartment on the port side. At that location it doesn't look like it would be much above the waterline, but I don't have an exact measurement. I am trying to find out if owner's of boats with Perkins engines have had problem with valve leakage or other issues and may have re-routed the valve to a new location, or perhaps abandoned it altogether. Please help...
Thanks. Dave
