sea strainers

[Fishermanjm]

i have heard talk about sea strainers on this site, i know my classic doesn't have one installed on it now. Is it a good idea? Is it a preventative measure? also would a thru hull fitting be used with one?

i just got mine on last week.i re plumbed from the drive to the sea pump..basic thing is you are catching anything in the strainer before it gets to your motor.if you sit low in the water you may need a ball valve before the strainer to to allow you to open the strainer while in the water and not flood you out..some plumb in flush kits so there is no need to open.
when i was asking the questions you are asking well only one person said that they thought it was a bad idea to draw through the drive.everone else said it would be fine

Use a BRONZE strainer! Stainless looks pretty and yes more expensive but will let you down. I and others have first hand experience, me quite a bit more than others being i the working end of the boat biz. Check the posts below! I dug up one members post below! http://www.donzi.net/forums/showthre...=sea+strainers If you do insist on S/S bling do a very good job both bonding and zincing it!

While everything since the TRS has drawn cooling water through the drive,
it's not necessarily the best way to get the cooling water into the boat.
The drive MFGRS do it that way to make it easier to assemble the drive package into the boat.
If you're NOT a boat builder, there may be improvements you can make.
A through transom pickup will gaurantee a better route for the water to get to the engine.
Once inside, a shut off valve can be added to the inside
nipple of the pickup for safety's sake. Then the strainer
can be added enroute to the seawater pump.
Maybe some pictures of a couple of different boats will
help to illustrate installations;





A different boat, a Minx, the inlet check valve turned out to be unnecessary;





I have more if you need them.

My Sea ray has them all over. They are great to have, really help when water isnt the cleanest. Baltimore Harbor is famous for cloggin up strainers and usually wash them out when were on the hook

The strainers, or the pickup???
Due to the price of copper today, ya have to shop carefully for the bronze strainer.
Like MOP says, it's the only way to go. On eBay, you can get a 1", or 1-1/4" for a
minimum of $100.00. Maybe $150-$175.00.
The SM pickups go for $165.00, but I've bought a couple on eBay for $50.00.
But be prepaired to wait awhile for it.

Thanks for the info George, the thru hull inlet is mounted
to the stern,,, does it hang below the bottom? The raw water
is almost forced in when underway? Is that correct? The strainer
makes sence to me now, it will keep silt an muck from getting
inside the block. I got my classic just in time to winterize it. I did
notice some black dirt an mud was plugging up the block petcock.
Can I buy that type of pick-up or did u fabricate that? If u don't mind
please send a few more pics. I want to get it right first time. Thanks guys

The pickup is a Stainless Marine piece, 1" pipe through.
Here's the site;

I really prefer a Perko strainer in 1" or 1-1/4" size. There're others available but I don't think they do the job of the Perko.

Here's the pickup on my TR that I'm currently working on;



And don't forget to block off the hole through the gimbal. That's a stock Merc part along w/a gasket. Otherwise it sinks.

Got it,,, thanks agin George, if the snow around my boat would melt,,, i could get to work on it,,,

Not as pretty an instal as George's and a little different, but gives you an idea on a similar set-up, I also added a flush out line.

[Fishermanjm]

There is a factory part that closes off the gimble feed end,,, not just a plug for the hose end?

[fogducker III]

Not sure if this is the one or for the exhaust outlet but similar idea.....
