Is it normal?

I have had a 270 for three years, my first boat. Next to no problems with it, but I don't do many hours. Yanmar 4LHA engine with a Bravo 2X outdrive. The engine is cooled via heat exchangers from water that is sucked through the outdrive by an engine mounted pump in the normal way.
The question I would like to ask is:- is it normal to not have a water strainer or filter of any description? In my boat a pipe runs straight from the outdrive, through some connectors and into the pump. I can see no evidence there ever was any sort of strainer.  Your comments would be appreciated.

    I have 2 Yans and I have 2 thru hull valves piped to each strainer then to the engine. Also the water sucks up from each drive.

    So you really need a strainer to keep larger items from blocking the small tubes inside the heat exchangers

     I am a diesel fan with a petrol engine  but then I from England..... not Europe anymore thank god!   Yesterday I filled up at my marina and was met with a puzzled look by the chic on the pumps. "I've never filled a boat up with petrol before" she said! "Everyones diesel!"  She gave me the stare my kids give me when I ask about computer games!

    That must have been a pretty penny.

    When I was in England years ago I saw pumps marked "DERV" and was curious what it was. I was told it means "Diesel Engine Road Vehicle" I assume so they can tax the heII out of it unlike heating fuel.

    Dalek,

    The answer to your question is that it's pretty normal to have no separate strainer for cooling water on a boat like yours.  If you run a lot in very shallow water kicking up sand and muck continuously you could think about adding such an accessory.

    In general, Rinker puts strainers on boats that have dual pickup (water from the outdrive, plus water from a thru-hull with a Y-pipe).  For engines that take water only from the outdrive, there usually is no strainer.
