I have the 1100 bag in the front, 750 bag on pass side and 650 bag on the driver side. To get both sides of the wake even i have to fill the 750 full but can only fill 650 less than half way. I usually have me and a spotter sitting on opposite sides. We weigh about 20 lbs different. Can anybody tell me why this is? Could stock prop with some wear have anything to do with this?
