What kind of strainer to use?
 

My boat, for some reason, has no raw water strainer on it. Is this normal? I am always used to seeing them on the past boats I have owned. Also, has anyone used this type of strainer before?

Jabsco - ITT Corporation: Jabsco Pumpgard In-line Strainer Screen 36400-1110

This is much cheaper than the bronze ones that are $300!
