Was out on the lake for the first time this season. Left the dock and was taking off slow. Was running about 19mph when I gave it full throttle and the rpm's went thru the roof but no more speed. I stopped the boat to see if something was stuck on the prop. but was clean. Put it in gear and started slow and all was fine. Tried to give it more throttle and it did the same. RPM's went up but the boat did not speed up. I limped the boat back to the launch and pulled it out of the water. Pulled the prop and the spline looks good. What could it be? Is there a bearing in the prop that could be bad causing it to slip under greater pressure. Please help.
