I have read many postings regarding foam and replacement, flooring etc but my question is more in a troubleshooting line. I have an 88 boat which has spent most of its life stored outdoors. Winterizing includes covering etc but none the less over the years water has on accasoin gotten inside of the boat. Now I am concerned that the floatation foam has become saturated. What is the best and/or easiest way to asses the condition of the foam short of ripping up the floor?? My flooring, while haveing a slight soft spot or two, is in fairly good shape and I hate to rip all of it out without knowing it need to be. The reason I ask is I seem to have lost 5 MPH or so of top end and with all of the extensive engine work I have done and the fact that the engine is performing very well, I am suspecting I may be hauling some extra weight. Thanks for the inputs.
