I'm mounting a 70hp Yamaha on a 17' semi-v hull (6.5 degree deadrise@transom). There is a skeg that runs from amidships all the way back to the transom that is approx. 1"W x 1.25"H high. Should I have the a/v plate even with the bottom of where the hull would be without the skeg or even with the bottom of the skeg? <br />Thanks
