I'd suspect either a dirty hull or a cavitating prop. When you get near redline does the motor sound as if it is under load or could the prop be spinning in the air.<br /><br />Also you need to check your trim position. Another possibility is that you are carrying excess weight in the form of waterlogged foam.

I dont know if an i/o has a rubber hub in the prop but if it does it may have a spun hub.<br />You can remove the prop and mark the hub,run it and check the mark.A prop shop can rehub the prop.

The fact is that maesj1 hasn't bothered to give enough information to begin to make an educated guess. :rolleyes:
