Survey Found Raw Water Intake Valve Operational Deficiency

            In conducting a survey, of a 1995 30’ production express fisherman (built in USA), powered by twin 6 cylinder diesel engines installed new in 2009, a raw water intake valve with a restricted operation situation was encountered.




            The photograph shows how full operation to close the Raw Water Intake Valve is blocked by the recently installed “bilge step board”:  The step board needs a cut-out so that the valve handle can be rotated 90° and be closed.  Additional issues are:  A) single clamped hose (the barb was too short for double clamping).  B) bronze valve & through-hull are not bonded. 

C) the installed valve is in-line type and not the more preferred type flanged type sea valve.
