washdown thru hull strainer help

[bigeasy1]

This question has been asked by others,but can't find it.I am planning on placing the thru hull for my washdown on the outside starboard step closest to the chine,and only about six inches in front of the trim tab.

Will it affect the dynamics of the tab as far as lift?
I'm going to have a scoop strainer on the hull,so it will work to help push water to the pump while underway.

This is really the only easily accessible location for the seacock.I prefer to put it on the port side on the second step in from the chine,but my transducer is right there,and the second step on the starboard side leaves me extremely difficult access to the seacock.

The second step in also is where the trailers rollers are located,so thats also a problem.I also don't want issues with the kicker motor.

I'm attaching a picture showing the transom(not quite finished) with the kicker and tab showing.

Any comments or help would be appreciated.Thanks all.
