I am running Livorsi 5" cans on 600SCI (twins) with Merc XR low water pickup. They work very well but need to be cleaned out after 1 hour of running through Kelp patches and Turle Grass. I would like to change to something that has a "back flush" feature to dump the seaweed into the bilge. Anyone know of a product that has this? Or can I make up a systme with ball valves and hoses to create a back wash?

Oh yeah- I also like the fact that the the nut, lid, and strainer basket all come off as one piece ( you can separate them later if you want) but its a quick process with no small parts to lose.
Get an integrated flush out so you can screw the hose right into the boat, it will help dramatically with flushing and keep the impellers running longer-
Make damm sure you keep the length between the strainer and teh impeller as short as possible- too much length and youll lose impellers left and right.

Has anyone tried this type?

Not as pretty as the Marine Machine strainer, but it seems it would still function the same and cost is about 1/4 the price of the Marine Machine strainer

Any length more than the minimum necessary to make the run is one definition. Ive see then plumbed from right at the stern 8 inches from the sea pump to all the way to under a ski locker between seats- its common to mount them in front of the engines for convienence but the hose length gets long pretty quickly.
The longer the hose the harder and longer the water pump runs "dry" before getting wet.
Too much is any length too long to fill the strainer when completely dry before eating an impeller. I learned the hard way to ALWAYS prime up a strainer after the boat has sat and drained down completely.

Correct me if I'm wrong but my understanding on something that hasn't been addressed so far is if your boat comes out of the water, the sea strainer will hold some water so the impeller doesn't become dry, and the 10" would hold more water then the 5", which means it would better protect your engine.

Yes, and bigger strainers can buffer "air time" better than small ones and can fill back up quicker than teh suction load on them.
The issue with line length is the dry run time at start up and the amount of vacuum your pump must pull to prime the system first shot.

Those are Gil/CORSA units, which I have on my boat. The band clamp can be a bit tough, depending on where you have them mounted, but as long as you keep a little silicone grease on the lid o-ring, they work very well. No tools required and reasonably priced. Available in several different right- and left-hand layouts.

I have a couple Gil/CORSA units and they work fine. I agree with ActiveFun, they can be a pain to get sealed back up and the clamp can be hard to deal with also.
I have a question about mounting....Is the height of the strainer critical? I want to move mine up say 2" rite now they are flush with a floorboard in my motor compartment and that makes dealing with that clamp a bear. Can I safely move them up?
