Product Description

New exhaust manifold for GM/Chevy 305 cu. in. and 350 cu. in. V8 marine gas engines. This is a direct replacement for many center-rise Barr, Indmar, Mastercraft, and Marine Power exhaust manifolds, and is compatible with any of my Indmar risers. Compare your casting numbers to the cross-reference below. This manifold comes with a full gasket and bolt kit. It will fit either side of the engine. Each purchase is for one manifold.

Riser mating bolt dimensions are 4" (101.6mm) by 2-5/8" (66.7mm) bolt center-to-center.

This part is new and high-quality cast iron construction. To determine if this is the correct replacement for you, look on your current part for casting numbers and match them to the cross reference below:

Cross ReferencePart Number

Indmar53-1027
Osco Motors994
Barr MarineCHV-1-83

GLM Products56230

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.
