I have another newbie question for everyone. Yesterday we went for a trip down the sanitary and ship canal. There was quite a bit of debris floating and I was bobbing and weaving to avoid the junk. After about 8 miles I goosed the throttle a little to get the bow down and it stuck for a second and then it felt like it let go and the RPMs spiked. I repeated this test several times and had the same result each time. I thought for sure I hit something and spun the hub. I turned around and headed 2-3 miles back. For reassurance I tried the same throttle maneuver again and to my surprise it didn't slip but held strong and got me up on plane. After it held several more times I turned around again and headed for the city where we enjoyed our day. We decided to cruise the lake back to the calumet river which is 12 miles or so and we didn't notice the problem re-occurr. So my question is this: is it possible that I had a bag or other debris around the prop that was causing this issue. Or is it possible that a spun hub would only slip part of the time.
