Default Sea strainer location

Working on installing a strainer into my 24 outlaw. Will the location in the picture below work?

thinking of adding a 90 to the back for the outlet and looping behind the batteries so the loop is less severe and give me a straighter shot into the raw water pump. Adding a relief off of the strainer to dump excess pressure over the side.

I don’t think using the current outlet would be possible as I can not find a molded 90 that will be suitable and I think the 1 1/4 hose will add to much stress to the housing.

any better ideas?

If you were to put it closer to the transom you wouldn’t need to worry about the 90 degree fitting. Probably need to move the batteries forward.

that’s definitely an option, but is extra holes in the bilge better than adding a fitting? I guess I have to put some extra holes in regardless to mount the strainer.
the other side is pretty much wide open other than the trim pump. Would have been nice to put this in when the engine was out of the boat to get a drive guardian installed.

I tucked mine up on my transom for my outlaw 24. Then AN lines to raw pump and pop off pressure release.

In theory you can mount the sea strainer anywhere you want. The raw water pump will pull a vacuum and pull liquid into itself.
"Ideally" the best location would be as close to the through hull as possible and the strainer would be mounted low enough to be flooded with liquid all the time yet high enough that you could open the lid even when running and not start filling the boat......in-case you needed to do some maint or clean things out. I have also seen guys install a "T" fitting with two valves on the inlet side as well. In the worse case scenario where your boats taking on water and the bilge pumps cant keep up you could shut the main feed line valve off and open the side port valve that would have a line going to he bottom of the hull in the bilge and the motor could suck all the water out and help the bilge pump as well.....

whats the reasoning here? Most strainers have a port just for pressure relief, dont want your strainer lid to break or its going to be a bad day.

I would put the relief valve at the exit of the oil cooler. You want max flow through the cooler. If you set the valve at 20 PSI it will be 20 PSI through the system.

interesting, My thought was relief as close to the source of pressure which is my water pickup. Concern I would have with putting it at the cooler is the raw pump would shield the system and by the time cooler is seeing 20psi strainer would be much higher. I have water pressure sensor at engine, maybe ill put one pre raw water pump. Would be interesting to see if my theory …..holds any water .

Your pressure is coming from your sea pump.
