Note:
This manifold does not replace Indmar 53-1051, which has longer exhaust ports that space the manifold out further from the head. This only replaces Indmar 53-1027. To determine what you have, measure from the top of an exhaust port to the inner side of the manifold. If it measures approximately 1 inch, you have the more common manifold that this replaces. If it measured approximately 1.5 inches, you have the manifold with longer ports that this does not replace.
