Mystery Fitting

[My Cyn]

Hi Folks,

I had an opportunity to spend some quality time in the bilge this past weekend. Attached is a photograph of a fitting on My Cyn that has me stumped. I am referring to the component held don by the metal strap, fastened with the two Phillips head screws. . It is part of the piping system that runs between the sea valve and the water pump on the VP MD11C.  I am trying to figure out its purpose. It may be a y-type strainer. Interested if anyone has any more or better information.

Cheers!

It is the raw water strainer. The opening is aft and at the bottom of the unit. The semi ring with the bolt is where it opens for cleaning. There is a screen mesh that pulls out.
BTW: It looks like you have another strainer attached to the clean outflow, good idea.

Bob,

Thanks for the info.

The last engine mechanic installed the second white basket strainer downstream of the wye strainer. I wouldn't be surprised if he removed the screen from the wye strainer during that job. The photograph show what appears to be a homemade gasket (red) at the opening, along with some caulking/sealant. 

Access to the basket on the wye strainer could be better. The photo shows the space constraints. I have tentative plans to remove the wye strainer and replace it with a larger Groco basket strainer, positioned so the basket could be lifted straight up and out.

Regards,

Bill

Sounds good. I clean mine once a year, we get a lot of eel grass in NE.
I use a rubber gasket from Lowes, works fine and never leaks
