Went out this weekend. Boat ran good. But while trying pull the kids on a tube, the boat would begin to pull, start to incline. I began giving more throttle to level it out. The Rpms climbed, but was not going any fast.
Is this a prop issue? Air in the water? The area in which this happened was somewhat weedy. I have pulled people on a tube before much heavier then my young kids. Didn't really experiment to much. It happen a 2-3 times..but not every time. Thoughts?
