Re: PROP LOCATION NOT BELOW BOTTOM

cavitation plate, which is the plate that you would hook hydrofoils on, or the bigger looking wing above the prop needs to be level with the bottom of the transom, give or take an inch. Do you have the motor tilted at all. If tilted up to much, when you pick to boat up out of the water on plane, the prop will lose its bite. Good luck, let us know what you come up with
