One of those things that has been learned the hard way is that the white foam fishing noodles deteriorate if left exposed to sunlight laying in the bottom of the boat. We normally contain them in a nylon mesh bag. After a few months they start to crumble on the outside. A fishing buddy of mine is discovering pin holes in the bottom of his boat which does not have a floor in it. Another acquaintance has the same problem and says that it is caused by the foam particles. The boat is a late 70s model that has more use than most. Does anyone know if the foam is the culprit? He is planning to remove the motor turn it upside down and have a rino liner finish applied to the outside. This is a wide 16 ft flat bottom he has a 75 hp Johnson so there is enough power to spare. What are your thoughts? Will it work? Will it stay on? How will the boat perform???
