Hey<br />On my 18 ft gemini bass boat i have a 125 rude long shaft... center of prop is about 3 inch's below the bottom of the boat. i went to a local prop shop and almost knocked the guy out beacuse he was tellin me that it wouldn't work. the boat just won't get on plane. I know many people with bass boats and i've gone and looked at theres. all there props are the same amount lower than the transom and theres works... do i have the wrong prop and the guy is full of it at my local prop shop?
