Raw water strainer size??

[Northeaster]

How big of a Perko or Groco strainer should I use with a Yanmar 2GM?
Have a cheap plastic one now, that may be leaking air.

I will check the water pump hose size tonight, but it's approx 1/2" - 3/4'.
Does the strainer model 3/4" or 1 1/2" mean the basket size, or the fitting / hose size?

Thanks!!

The inches you are referring to is the fitting - hose size. THe strainers are measured in ml as I recall.

Thus, a graco 3/4 npt 755 would be a 3/4 inch fitting 750 ml strainer.

As far as the size, I have always been of the opiniOn that the bigger the better. Still, I bet 750 ml would "work" for you, with larger being better. Check with Yanmar on that and do not quote me on the size. But get rid of that crappy plastic one!! THe bronze ones are sooo much easier to clean and a much better product in my opinion.

Simply match the hose (ID) size on the engine to the inlet/outlet size of the strainer ..... and all will be 'optimized'.
