Have a 85 imperial 19fter, great moter. Anytime you start out with statement I guess its safe to safe the floor and transom are shot. I picked up the boat dirt cheap, tore out the floor to let it dry out and am now ready to start. The stringers are tolerable but I will probably replaceable seeings how the whole boat is already torn apart. here's my question...the foam, how do you remove it without destroying the hull? Any assistance here is helpful. Had a wood boat for years, this is a fiberglass hull.
