While running my pontoon yesterday I encountered a loss of power problem. I was running at full throttle and suddenly had a loss of power, it slowly picked up speed and ran normal for a couple of minutes and then started to lose power again. RPM's drop from 5200 to 3000 and then pick up again. This morning the boat started up normally and ran normally for about 5 min and the problem started again. Any ideas where to start to remedy problem.

The prop hub could be wearing,causing slippage.
