Been working on the Epic all day- I don't think there is an easy way to change the oil in these boats but I am sure I made it harder then usual! haha- I have an x22 and after draining the oil and replacing the filter (mobil 1 for both) I filled it up with the 5.5 liters it should of taken. Nothing registered on the dip stick. Not one drop- So, with the oil cooler "How much oil should this boat take?" Don't want to over fill but I added and extra half quart already and still nothing... The dip stick isn't orginal so I am wondering if that has something to do with it.
