For my 1998 25hp Yamaha it is to much pitch lugs the motor. 10 is not enough it cavitates. so maybe an 11 is my sweet spot. having to try all 3 is frustrating, but if it does get my boat out of the water quicker and down the water smooth smiles will be had. Have a great day boating and smile the bugs are great protein. LOL
