Please, for your own sake, don't buy that strainer. It's barely worth the cost of the corrugated cardboard packaging it is shipped in. I had one on a Catalina and it was one of the first things to go!!
For what reason? Too small, so it filled-up/plugged too fast?
The reason I ask, and the reason I'm hesitant to spend $150, vs. less than $50, is all we're talking about here is a relatively crude strainer of which not all that much is demanded.
We're on a well at home. It's got a 1 HP pump capable of delivering 18 gpm. (And it does it, too. Trust me.) It pressurizes the system to over 60 psi peak. Between that pump and the water softener is a filter--all plastic from top-to-bottom. It has a 5 micron disposable filter cartridge in it. Now I figure if a piece of plastic can stand up to years and years of what our water pump can throw at it, at 5 microns, no less, certainly a well-built plastic strainer can do no less for significantly less volume, pressure and fineness.
As for bronze barb fittings Jamestown Distributors, Hamilton Marine or Defender all stock them..
Ok, I'll check those out. Thanks! (WM doesn't have all that good a selection, looked like.)
You want a real bronze, easy to clean strainer like this one made by Perko. It will hold LOTS of grass and sea weed before it reduces flow!!
I certainly want it easy-to-clean, which was one thing I liked about the Shurflo design: The bowl unscrews. So if you get it filled up with sediment, you simply unscrew the bowl and dump it out over the side. No muss no fuss. (Just like our home water system filter.)
want whatever I get to hold lots of grass, weeds, etc. before flow is significantly impacted.
Here are some ideas:
#1 You want the least amount elbows on your way to the strainer as possible.
I knew that, but thanks
#2 You want to use the biggest hose on the way to the strainer as possible. If your thru hull is a 1" full flow use 1" hose. If it's a 3/4" valve use 3/4" hose. I recommend ...
As I said: Looks like the current fittings are 1/2" NPT. I appreciate the recommendation, but I'm disinclined to replace a thru-hull that seems to be providing ample water to the engine. Besides: The current pump is only 1/2" NPT and the one I'm thinking of replacing it with is less, at 3/8" NPT. (Dunno why.)
#3 You want to use either bronze or Marelon for all fittings bellow the waterline!! No nylon or PVC!!!!
Yup, that was what I wanted.
#4 You want to use wire reinforced marine hose to keep the dia of the hose constant even with a radius bend.
I wondered what kind of hose I wanted. Thanks. I may have to replace all the hose.
P.S. Never mind you're on a rather sea weed free lake... I'll leave the info for others.. the advice about that strainer still stands though...
from anything resembling "seaweed-free," believe me. In fact: We're slipped at the end of a canal and sometimes the entire surface is a weed mat. One reason for the strainer, and one reason I want the screen area to be as large as I can fit in the available space.
You know, I wondered about those. Funny thing: When we were discussing fuel/water separators/filters last season, I used that same picture and I don't recall anybody saying anything about those copper lines. Maybe I just forgot. New-to-us boat, lots to remember
Thanks for your comments, halekai36. I may not follow (all of) your recommendations, but that doesn't mean I don't appreciate and respect your input.
