Depends on the 90HP motor... 4 cylinder?  3 cylinder?

Generally speaking, expect about 8-10"

I have a 170 with a Johnson 88 spl.  I believe the bottom of the skeg is more than 10" below the hull though, so I'm guessing that 'at rest' the total draft is going to be closer to 18".  Shallower on plane of course.

I'll measure for you.  The cavitation plate is in the correct location and my transom drains sit just above the waterline.

I think my boat draws 8" empty.  When I have a full load it gets closer to 12".  I have a jackplate on my boat so I can run with the prop center line about even with bottom of the hull.  On a good day I might be able to run in 9" of water for a short run.  I know I have crossed shallows near Pine Island that were 18" deep.  EZPZ.

akbridge - how far from c/l of your prop, to the bottom of your skeg?
