I have a 22ft dynasty boat (was used for towing)<br />that wount plane unless i have atlest 150 to 200 lbs in the front.Could it be my prop and if so what prop do I need
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.
