Hi Rob
Good to see you the other day in Noank. We have the Yanmar 3GM with Sendur fresh water conversion. Raw water inlet is ½ inch opening with no strainer using proper barrel type seacock, straight hose connection to a screw on plastic strainer then hose to engine. The strainer is forward of the engine with clear plastic barrel so easy to see each time we move the stairs. I make it a habit to unscrew and clean every few weeks as it does catch eel grass and gets crudded up. I also listen for healthy water flow from the exhaust every time I start the engine. No problems for 16 years now John and Maryann Legacy III 1982 C&C 34 Noank, CT From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Robert Gallagher via CnC-List Sent: Tuesday, August 18, 2015 10:16 PM To: cnc-list@cnc-list.com Cc: Robert Gallagher Subject: Stus-List Raw water intake fouling A4 I went from a 30-1 with an A-4 to a 30-2 with a Yanmar 2gm20F. My AF had no 90 elbow from the seacock. No internal strainer, just the little colander screwed to the outside of the hull. My Yanmar has the 90 degree elbow, internal strainer, no pasta strainer on the outside. Well, last week I started motoring and the Temp alarm went off. I shut it down and checked the internal strainer and it was clean enough. Started the engine, no temp alarm but I could see straight away no water coming through the exhaust. Pulled off the hose and opened the seacock...barely a dribble. Pulled off the elbow and I could see seaweed jammed up in there. The top of the 90 deg. elbow has a threaded plug so I removed that. Still had a job getting the jammed up weed out with needle nose and a screwdriver. Thinking of putting an external strainer on the intake this winter.... Good idea or NOT so good?????
