I went the other way on the re-foaming. I have a 1966 17' OMC Dual Deluxe.
The foam was saturated and wouldn't dry so I removed everything down to the
hull. Then I built a new floor, resined the seams and edges, and drilled
holes to pour in 2 part foam. It filled the hull and raised the floor. Very
solid and firm. Just wanted you to know that either method can work and that
it can be very exciting working with 2 part foam.

I guess I didn't proof the text well enough! You need to make sure you don't
over foam the hull as you will have to sand a lot of foam to get the floor
back to the right level so the sides will fit back into place. You will
become aware of this as you take things apart. I pulled the floor out and
saved as much as I could to use as a template to cut the new plywood.
Measure everything. Look at everything like seams and where the T nuts are
placed - you need to measure their location so the seats will go back in
proper position or otherwise you can mount the seats with wood screws. Don't
screw them through the bottom! There will be a ghost edge at the floor and
you don't want to fill above that level. You can leave 2-3 inches of the
original foam at the edges to act as a ledge or level to know the height you
need to refill. I think the factory put the floor in first and then injected
the foam which expanded to fit the cavity. I did the reverse. I would pour a
small amount of foam and put plastic sheet and a board on top so the foam
would expand just to the height I wanted. Remove the sheet which will not
stick to the foam and do another section next to it.You figure it out as you
go. The foam is a 2 part mixture you mix and pour and it expands rapidly and
with some force. It is cured say in 5 minutes. I wanted my floor to be as
close to original so I didn't have to re-engineer things. The whole project
took months as I am slow but the end result is perfect. I used regular
plywood and common fiberglass materials. I used materials from a company
called Fibre Glast - they do a nice business on line and ship fast. You want
to use fresh materials. Let me know if this helps or if you need more info.
I could spend hours on this subject. TK
