Sea strainers mounted below water line still could not start a syphon of into the water because they are above lower gear case pick up, right?

This sounds like you want to get this right or you sink!
So u are saying that if your boat ,,sits in the water, the gimbal is above the waterline ????????????????????:rolleyes:

The water inlet connecter on the Bravo transom assembly is above crank line center about 3", but pretty damn close to the water line so the shut off valve is ok with me.

I assume with a Bravo install the Sea Strainer is put in the hose line coming from the Bravo, Then plumbed up to the input side of the sea water pump. I have considered putting them in as well but didn't have a great option for running the lines without a few 90 degree bends. Does that matter much for flow pulling the water through the strainer as well.
What about all those elbows?

Understandable to put a valve in before the strainer so you can close the line off when cleaning out the strainer. But question.?? You could always get a hole in the line in between the transom assembly and the shut off valve. I'm not trying to jinx myself but that would probably happen to me. I would be takin on water and have to drive her to the beach and beach it.!! Anyway how about the 90 degree bends to try and make the plumbng as clean as possible, no issue with water flow if you are only pulling from the Bravo. ??

Can sea strainers also be installed between the sea water pump discharge and the oil cooler to catch broken sea water pump impeller parts?

The object is to stop the sh!t from getting to the pump so it does not tear it apart. I think it would be cheaper to service the water pump on a regular bases rather than waiting for it to fly apart and running two strainers. But thats just me. :rolleyes:

I talked to a guy that ran a T and shutoff valve on the suction side to the bilge to use the engine as a emerg. back up bilge pump. I would think a 1" line and a V8 could move some water if you ever had the unthinkable happen.

Now that's a nifty idea! :ernaehrung004:
