Intake screen
Hi: I'm trying to replace engine water intake screen while in water on a 1975 Marine Trader. It appears to be 4x7 screen that slides into place. I am trying to find a replacement or make one...Anyone have any ideas/experience? Thanks

I'll check mine when I go to my shed. You can buy it as I took mine off.
I've seen them online but a quick search didn't reveal your type...I think West marine carriers them.
You might consider leaving it off if you have a decent internal strainer.
Through the years I have found the external ones clog just as much and cause the same issues...but you have to dive to clear them. Leave it off and you can just jamb something through the seacock and clear it. Plus nothing can grow on and clog a hole...just the screen.

GROCO MARINE PRODUCTS Try the Groco APHS series. Removable screens with a door that opens for cleaning.

That's why I opt for no exterior screen at all...
I think this guy wrote someplace too that he doesn't like them..

I know this isn't going to be a solution for everyone.I carry a small 3 gallon compressor for inflatables.My thoughts were to install a T in the line to the thru hull strainer.Then install a 1/4 turn bronze ball valve with an airline fitting.Then I could plug my compressor up to it, shut off the valve at the raw water strainer, and blow out the intake line and thru hull strainer.

Won't work with most seaweeds on the East Coast...the system isn't really airtight and the seaweed tangles up in the strainer...sometimes ou have to pull it out with pliers...even backflushing won't work much of the time.

Interesting idea. It could work if the lines and fittings are rated to hold up to the PSI of the compressd air if there is a total blockage or something that doesn't clear.
And then you have to worry what your dock neighbors will say when your boat "farts".

Thank you so much for the advice! I will keep looking for a replacement screen but in the meantime sounds as if I keep my strainer clean and maintained I might be ok for at least short periods of usage. The seacock has a short, straight shot to the strainer... thnaks again!
