I own a 2K Ski Centurion with the Mercruiser 270 HP 5.7L Inboard Tow Motor. I want to change the oil.<br />I have removed the drain plug from the bottom of the hull and I have run the oil tube (?lack of better words) down through the hole. I have unscrewed the cap on the oil tube yet no oil is coming out. What gives? How do I get the oil out? I know this may sound ridiculous but this is my first time doing it. <br />Any help is appreciated.<br /><br />Jim
