I am replacing the Bellows on my 87 OMC Cobra outdrive and the exhaust bellows my local dealer gave me does not match the one I took off. One section running the length of the bellows is cut such that on the high ribs they are "Ground" down to create holes into the bellows. My question: Is this a new style and can I use it in my Cobra application. My manual makes a reference to an exhaust relief for the U-Joint bellows on a King Cobra but I think it was a typo and they ment to reference the exhaust bellows. Does this also apply to the regular Cobra.<br />Thanks in advance for your help. This is a great forum.
