It is funny you say that about parts...we took the family out sailing this weekend and had a great time and the engine ran flawlessly. Now that the family event is over, I am getting ready to rip it all apart again to start the FWC install..I am making up my Moyer list for Ken right now!
Neil turned me onto a (relatively) cheap raw water strainer that is simple and plastic and easy to mount & clean.
It is available on ebay from the "boaterbits" store...$30-ish
edit - use this in the ebay search engine. "BOAT RAW WATER INTAKE STRAINER FILTER "
