Product Description
New exhaust manifold conversion kit for OMC Ford 302/351 marine gas engines. Replaces the old end rise (log style) manifolds and risers, part numbers 913682, 913683, 909218, 982680, or 909863, with new and more efficient center-rise manifolds and risers. Includes 3.5" exhaust hose to mate up to your original Y-pipe.

Note
  • This kit does not replace the older "Banana" style OMC Ford manifolds.
  • These manifolds utilize one bolt per port, instead of two like original OMC manifolds. This is normal and will not cause any problems.

Shipping Note: Due to the weight of these parts, this kit ships in multiple boxes. When you receive your tracking number, be sure to track it on the carrier's website and find the "Other Packages in this Shipment" section to track all of the individual boxes. For standard/ground shipments, they may arrive on different days.
