My floor had an extra piece of plywood under it near the stern. It was
almost full width and about 2 ft long - basically the size of the motor
well area. I assume that this was there for extra strength where weight
would always be present (battery and outboard fuel tank). I also wonder if
it is because the hull was the same for outboard and sterndrive models.
 The sterndrives must have stronger stringers though . . . Does anyone
know if their floor was similar - whether outboard or sterndrive?

I am at the same point and hull is "empty" I have some good photos as
well. I did it early this summer then well you know ....time flies....
 Anyway I am thinking 4 lb as well. I just want to be sure as my 14' has
no structural stringers only the foam and floor. It is an outboard so that
may make a difference in the original design and the need for floor
