The '89 Freedom glass boat I just got has a heater setup useing the engine coolant running thru line up the side of the hull to under the passenger feet area. The lines along the side appear to be PVC type of tubing. They have a swollen look to them but I have never heard of PVC swelling but I could imagine the heat and antifreeze affecting them after 10+ years. Are these things PVC that are about to blow or are they fine and or should I replace them with new tubing or regular auto heater lines??? thanks
