My strainer was mounted below the waterline by the PO. Everything under the quarter berth is below the waterline. Anywhere in the engine compartment meant a lot more hose.
In my case it works out well. After pulling the hose off of the seacock to run a wire down the seacock to clean out the milfoil or eel grass, I then put the hose back on and take off the top of the strainer to see if I have flow. If not then it's time to take the hose off of the strainer and clean out the hose and input to the strainer.
I rarely have to clean out my strainer though. :-)
Maybe I should take out that elbow
on the input to the strainer, but then I still have to figure out how to get the milfoil and eel grass to get past the seacock.
