Anyone ever removed the floor from a 17' 2000 Express? I have cut all the visable welds from around my floor pan and I cant get it out. I have srcewed hooks in different spots around the floor and lifted it with my engine hoist and can lift the boat and trailer off the ground and it won't budge. All the welds are completely cut through. It appears that floor was put in after the rod box and sides because I can see the edge of the floor on all four sides. Any ideas? I need it out to replace water logged foam. This boat sat upside down all summer and the foam still has water in it. See Pics. Thanks
