Sea strainer plumbing
I am trying to figure out my sea strainer plumbing. Unclear about a few things.
I have transom mounted pickups to strainer Inlet with shutoff. Then comes something I don't get. I would be taking strainer out to the pump and pump to crossover, but for some reason, the strainers are set up with a Tee on the out side withe double 1 1/4" outlets. I don't get why two of them. I was thinking maybe they each go directly to the front engine ports but too big? This is a twin small block Chevy setup with 2 strainers. Also, with mercruiser pumps I suspect I need a pressure releif? I intend to run without thermostat until I find it won't work. Where should pressure relief be without and with thermostat? I'll have a dump from the trans coolers and hope to include releif dump together with it. Thanks for any help. |
Water enters strainers on top fitting and goes to engine from bottom fitting.
The T could be for a pressure bypass or for a fresh water flush connection. |
Strainer to crossover? Where is the sea pump in all this?

Seems a little odd for hose plumbing having the strainers mounted on the transom rather than the bulkhead. Regardless I'm assuming this is a barbed T or is it threaded. Either way aside from a pressure relief is it possible the T fed direct to both left and right side of block if running an open system with no stat. |
Griff had a good point also for flushing. Is there any garden hose connections near or around the bulkhead somewhere for flushing? |
There is a hose fitting in top of strainer.
I'm still a little confused for sure. |

Here are a few pics. As you can see in the pictures, the ends are threaded vs. barbed but I do know the hoses were actually clamped on the threads! I'm obviously changing to barbed fittings. Just trying to decide if and for what reason I need 2 on the output side. https://cimg3.ibsrv.net/gimg/www.off...deb8789058.jpg

Just looks like someone added to suit there needs for who knows what particular reason. I'd just remove the T and replace with a 90 or what ever works out best for routing etc. Not sure if your going to install pressure relief valves or not. Personally I wouldn't bother if your running stock mags or 330's. |
