Thats right Brian, you may not have to replace the wood under the cap up front, easy enough to check that out, when you make the cut across the floor, leavung a couple inches from the step, you can check out the forward wood, when you cut out the floor, leave a couple inches "safe zone" on the side cut also. By leaving a couple inches away from the step, and the wood up front ain't wet, then you have something to "scab" onto, to relpace the rest of the floor, and like it's been said already, it's a good idea to put the floor in two sections, I do three.
