I have asked this question before, but got no response so I will ask again. I have a 1981 merc cruiser 4 cyl. 4.0 engine. When I look for a manual on the merc site I only find reference to 3.0. Are these the same or what.<br />Thanks<br /> :confused:

never heard of a 4.0. Where are you reading that it's a 4.0? On the engine somewhere?
