Good Morning,<br />The last time we went out I proceeded to apply full power, it started to shake/vibrate with no response to the outdrive.<br />The day before it ran great, noticed some oil on the water coming from under the swim platform, when we returned to the dock.<br />Does any body have any idea on the cause or symptoms on this? <br />It is a King Cobra/OMC 460-7.5 Ford <br /><br />Could use your help!<br />Thanks
