Hi, I have a question for the volvo guys out there. I have a 1986 Searay 17'B rider that i want to transplant a 302V8 and aq200 outdrive in to. The boat HAD a 3L and alpha 1 drive in it. I know the transom mounts are different and need to know where i need to have the cavitation plate in relation to the bottom of the hull. In line or below the hull, if below how far? Thanks
